@Random Stuffs maybe I haven't seen one of the other "best" channels out there, but project farm is awesome. Not only does he test products that I use in my life, but does it in a trustworthy manner. And he's from Missouri, which is where all the cool guys live. 😎
@@mattschmitt9924 true there might be others, but PF is a huge channel by now but he still remains down to earth, reads comments and interacts and takes project feedback without gating it to "only patreons" that a lot of channel do(if you're a patron you can get to vote on teh next video, F U), his methods are also thorough and interesting
For non-catalytic engines it's been a practice of some - ever since leaded fuel went away from normal pumps I'd guess - to put a little diesel in with the gasoline fill-up as an upper-cylinder / valve lubricant. I've done this with motorcycles, older carburetor vehicles, and a fuel-injected Jeep Wrangler (inline six) that someone took the catalytic off of. They all ran great with that little bit of lube in there.
I remember when I was a kid my dad experimented with adding diesel to the gasoline in his f350 with a carbed 460. He came up with 1gallon of diesel to 10 gallons of gasoline and it actually increased the fuel economy a little and left a white coating in the pipes. Any more than that he got soot. All bets are off on a fuel injected vehicle though.
I don't even measure what I mix. Oil, diesel, gas, lamp oil, charcoal lighter fluid, moonshine, I just throw it all in the tank and my truck keeps on running like a champ. Multi-fuels are great.
All bets are NOT off with a fuel injected vehicle! I've used it several times in several engines inluding a modified Corvette LS1. I used a far smaller ratio, like 1cup diesel to 10 gallons of gas, and had only benefits, no cat issues, soot or anything. It essentially raised the octane level and stopped some minor pinging I'd been having even with high-octane gas. High compression engine was tuned for more HP and had the timing a bit too far advanced, hence the need for more than 'premium'. Essentially high-octane is harder to ignite (or in my Corvette's case 'preignite' due to pressing the limits of timing to compression ratio). Diesel is also harder to ignite, so the effects are much the same as higher octane. It's also an upper-cylinder lubricant, similar to Lucas gas treatment. It likely won't benefit lower performance engines that are running well, just like higher octane fuel doesn't. It's a misconception that higher-octane is more 'premium', other than sometimes have more cleaning additives than 'regular'. High octane is only harder to ignite (therefore reducing preignition in vehicles that require it- typically performance engines.) Like you said, you don't want to run the ratios you mentioned in a fuel injected car, too hard to burn completely (cleanly). But in the right ratios depending on your engines tune, works great as an octane booster!
Diesel fuel as well as gasoline are both great solvents. I've noticed at my shop when we do a diesel oil change and then do fuel filters the pan will clean itself out using the diesel fuel.
Honda enthusiast here..right or wrong on occasion i put .5 l of diesel in a full tank in my 20yr oldl RSX and it runs like high test..pulls strong..been doing it for 10 yrs and over 150,000 k- inspection camera on intakes- clean asa whistle-zero emission issues-runs like a top-and drive the shit out of it..260k+ and i figure shes just gittin broke in..LMFAO Eric,love your content,been subed for years,keep up the good work!
Hey Eric. I'm a Chrysler tech in Canada. Our Diesel nozzles are yellow or green, it depends in which gas station you go to. Back to the Chrysler tech thing.. we have both diesel and gasoline powered vehicles as you would know. So we do get both sides of the equation a lot more frequently than we probably should. Gas in Diesel vehicles doesn't seem to bother them much. We have been very lucky and only ever had to flush the fuel system out. Diesel in gas vehicles usually goes the same way but on 2 instances.. we have actually seen 2 engines that began to Crack the crown of the pistons as a result of trying to burn the Diesel fuel. Keep up the good work pal
My 6-year old son wanted to "help" my wife pump gas into our '95 Mazda Millennia. The car ran for 150 miles until reaching their destination. Next day, the car would not start. It was eventually diagnosed with bad fuel, tank drained, and refilled with gas. Car ran a little rough until the rest of the bad gas was out of the system. I contacted the out-of-town station about the bad gas, and after looking at the receipt, was told diesel had been pumped, maybe 1/3 to 1/2 tank. Unfortunately, the diesel nozle was the same size as gas.
Years ago a Trucker told me he would add a gallon or 2 of gas to his Diesel Tanks when going into subzero temperatures, He said it would prevent diesel from gelling up because of the cold. I once worked fueling Diesel Locomotives in Montana, We would add a couple gallons of Alcohol during winter months, I thought that was to help the water move thru the fuel system during the winter months
Yep the diesel treatments like Hot Shot and Cetane booster...is actually a volotile fuel like gasoline. He is absolutely correct. Unlike octane booster which makes gas ignite SLOWER, the cetane booster helps diesel ignite FASTER. Gasoline is the most economical common sense way to do so. There have been many cars through history which had diesel and gas tanks and used gasoline mixed in at startup then switched to full diesel.
I know a guy who adds a little diesel to the tank when he fuels up his GTO. He says it raises the octant enough to stop his high compression engine from pinging. I don't remember how much he puts in (per gallon), but I know he's being doing it since he rebuilt the engine back in 2012. YMMV!
I commented earlier, but I ran it in several modern day gas cars, including a modified (and ohh so fast) C5 Corvette (likely the same engine as your friend's, depending on his year) for the same reason. I ran about a cup per 15 gallons of premium gas. Because it was tuned, I could see on the computer that it allowed me to add more timing before any potential preignition. It also cleans and lubricates things better. I don't think it does much good for cars that don't need high octane, though.
The reason diesel is bad in gas, is that eventually the gas will separate out and sit on top of the diesel. leaving the pump sucking up a majority of diesel and a little bit of gas, so if it does run (poorly) it will do major damage with detonation. we had a Technician rev up an older engine after flushing the system out, but forgot to flush the rail so there was still diesel in the system, and it threw a piston through the block.
Great video. Very informative. One interesting thing I found out is even before refined peanut oil, Rudolf Diesel's very first attempt used coal dust as a fuel. It nearly killed him several times when the engine block exploded.
Few years back, a co worker put gasoline in a diesel vehicle of the company, and the result was - as Eric tells us - really bad. The car was "repaired" and ran a few hundred kilometeres, but soon enough, the car was declared dead, because is costed too much too repair it, given the mileage it had (190 thousand miles approximately)
Great video man! I've seen this happen a few times at my job both ways around - gas in a diesel and diesel in a gas. It's always a pain when they put gas in a diesel because in addition to removing all the bad fuel we need to change all the filters. And they take forever to get started again. I've never seen engine damage result from this, but that's not to say it can't happen. I have seen catalytic converters go bad on gas vehicles not long after something like this though.
The smaller gas filler neck was actually done to prevent you from putting leaded gas into your tank and killing your cat. It's just that Diesel-fillers are still the old size bc Diesel never really changed that much. The switch to LSD in the 2000s was gradual and did not include a change in filler size.
not it will not. it is like mixing milk in coffee. the only process that can separate them is the distillation process as they do for crude oil. So petrol and diesel will mix together and form a blend.
i have a 70s engine the hoses at the station were mixed up so i put diesel in it, it ran rough but still went once you got it going you could keep it going as long as the revs were up when i turned the ignition off the engine did keep running because the compression was igniting the diesel
Just siphon out as much as possible, change the fuel filter and then fill it up with gasoline. Top off the tank as often as possible. Drive it until the gas washes the diesel out. Problem solved.
In Europe Diesel pumps are marked black and Gasoline is always green - at least for the last 20+ years since we switched to unleaded. Gasoline pumps also have a much smaller spigot, so Diesel pump will not fit into the tank opening. Putting Gasoline in a Diesel is a common thing though. Modern Diesel cars seem to stop soon enough not to cause damage and the mistake costs about 4x what it costs to pump a tank of gas (1x for the gas you've put in there, 1x for the filters, 1x for service and of course you still have to fill the tank with Diesel in the end)
Decades ago I regularly added @ 10% gasoline & 90% diesel to my 1st gen Diesel Rabbit to give it a little ZIP...made it feel like it had a turbo which it didn’t. I ran it that way esp in the winter for 5 years
Back in the 70's granit haulers use to stop at a dinner in Vermont and put some gas in there trucks to lesson the fuel from gelling. That was when the temp would be well below freezing.
@@wallaceeverett3927 That is some trick I still know, and actually the only exception that allows putting gasoline into a Diesel. As you mentioned the Diesel starts gelling below certain temperatures, after a time it really gets some kind of nasty waxy substance. Adding at most 10 % of gasoline would actually change lower the gelling temperature and kind of disssolve the wax. At least here in Europe, they change between what they calll summer Diesel and winter Diesel in time. Winter Diesel has additives in it that prevent Gelling down to temperatures around either -20 °C or -30 °C, can´t remember actually. I guess its the same in any part of the world that may reach critical temperatures these days. By the way, you still can use this trick today, if you have a Diesel that gets only low miles and you put in fresh Diesel last time during the summer, just put in some Gasoline, depending on how much Diesel you have left in the tank. Alternative method: Use a torch or make a fire beneath the engine to preheat... Lets call it the "russian way". Not sure if anything not beeing an Ural or whatever will live through or not burst into flames. With modern cars you might get a heap of burning plastic way before the engine heats up...
Welp now I can see how someone foreign is going to mix those up. In Portugal at least, gasoline is labeled in shades of green (for the several octane ratings in RON) and diesel is labeled in black
That is the same as here in Australia. When they have them alongside regular fuel pumps there is often an extra lever that needs to be pushed down to unlock the the diesel filler.
@@AndreasKoepkeAU I guess the lever is somewhat of a fool proof method. Here you have to read to be sure (aside from the labels).Gasoline usually is 95/Premium 95(Both E5 - 5% Ethanol) both in dark green or 98/Premium 98(Both E10 - 10% Ethanol) in light green. Some brands also have "premium" diesel in yellow (Both B15 - Biodiesel 15%)
NoobGamerPT americans have allways everting in reverse. Remember they use miles, gallons, inches...etc Also, they only use diesel in SUVs and 4x4 trucks, the rest are gasoline. Not like in europe, more than 50% of cars are diesel, even small city cars. Or at least it was before diesel gate and eletric cars start to rise.
@@sjogosPT the same team which reported on VW diesels found after that BMW's, gasoline type, also over polluted than reported. No wonder Germany is getting in trouble with the EU for emissions in some of their cities.
I have run lawnmowers on 50/50 gas and diesel. I once ran 2 at the same time with the same fuel, one ran better than ever, and the other ran the last time ever. Both engines were healthy.
The issue is that diesels use diesel as a lubricant and gas goes not offer the lubricity that diesel does. So the components run without lubrication, frag out, and fill the engine with metal shavings. A modern diesel fuel pump is 5000 pounds of pressure, you need that lubrication.
My X-Wife put Diesel in my compressor when I was 3 stories up oon a roof it choked out and smoked like crazy ! After I drained the Diesel and put gas back in I WAS JAW DROPPED AT HOW GOOD IT RAN!!! I apologized for the choice words and insults involuntarily released in anger ( NOT INVOLUNTARY ) and told her this was the best mistake she had made that I had witnessed.
Just bought M-B CLK 320 for very cheap, because it would not start. It had missfire codes, thick gray smoke coming from exhaust etc. Then i realized that previous owner must have put diesel in it by mistake. Drained the old fuel mixture out and put 30 litres of gas in it. It started, idled roughly for few minutes and then it started running with no problems. Cheap fix.
Some BP stations have green handles on the gasoline side so be careful. I had a family member accidentally fill a diesel with the green handle and it turned out to be unleaded.
Yes, Damn BP! and there are lots of places with small fill nozzels on the diesel pumps. Some years of Chevy trucks have small fuel fills like a gasoline pump, so you have to find the small nozzels.
Duuuuude, Glad to see the vids and knowledge keep coming. Thanks for keeping me up to date on Hondas, Acuras, and cars in general. I do still refer to your videos from time to time for side work. Hope all is well in your world!!
A much easier way is to add some type of Upper Cylinder Lubricant. I cover a few products which I've ran for years with good results. Full testing and results of multiple products can be found on my channel.
Eric, I delivered fuels for many years, both gasoline and diesel. The tanks were never washed out. However, we did load gas into the container that had diesel to cut the diesel. But then you may be talking about 3 gallons leftover mixed with 3600 gallons of gasoline. Now deliver was extremely important. You had to be sure you loaded diesel only in a diesel tank at the stations, and the same with gasoline. 500 gallons of diesel into a 50,000 gallon tank wouldn't hurt anything much, except the driver's paycheck (which he no longer got from our company). Now going the other direction, if gasoline was delivered into a diesel storage tank and then pumped into a diesel vehicle: NEW ENGINE. Gasoline is too volatile for use in a diesel engine. It will wreck the injectors, preheat chambers, and the fuel pump. Rings tend to crack or break off. And then the oil gets diluted seriously. Moe
A colleague of mine went to refuel a Saab 9-5 petrol. He filled diesel in it and drove roughly 3-4 kilometers before the 2.3T suddenly stopped. Inspections showed there was a crack in the piston and the inspection camera went right into the oil sump. The engine ran fine before this, so we suspect it was caused by the mixing of diesel into the tank where the liquid wouldn't ignite.
Thanks for the video. My granddaughter managed to put 9.5 gallons of diesel in her car with an 18.5 gallon tank (gasoline car). Needless to say, once the mixture in the tank reached the engine it quit running. Once I figured out what happened, I siphoned out all the fuel I could get and filled the tank up with gasoline. After several tries and spraying ether in the intake manifold, we finally got the engine running fine. The check engine light is on now but I won’t be able to read the error code for a couple of days. Hopefully it will just be an error that needs to be reset with an obd2 reader.
You're obviously referring to an older carburetted vehicle. because any new vehicle has a small neck and won't allow the diesel fuel. nozzle. into the tank, In that case, yes, in a carburetted engine, it would not run well at that mixture., in a few injected engine. However, it has no choice but to get injected and burned. and it will end of story. Injectors don't care
It’s extra awesome when your delivery guy puts a couple hundred gallons of diesel in one of your tanks (ended up being around 30% diesel) and doesn’t tell you. We’re a fleet station and chased this problem for 2 weeks before I discovered what happened. I imagine there will be a lot of o2 and catalyst problems in our future. Changed a TON of plugs so far. Also can’t wait to see what possible side effects the diesel has had on any of the rubber or synthetic rubber components.
So I'm heavy equipment diesel mechanic and for about 4 years I ran a 50-50 mix premium gasoline and pump grade on road diesel in my 1993 Isuzu rodeo 3.2 l V6 did not notice any lack of power never had issues with injectors filters pumps etc like I said I done this for years The one downside was my vehicle smell like a diesel and older diesel it wouldn't roll call but you definitely had some unburned diesel smell on the exhaust this engine is still running today The rig is now a play toy 360 plus thousand miles and doesn't hiccup runs flawlessly
I was a mechanic in the 60's, to 80's, where I worked, there was a 5,000 gallon diesel tank that would get filled on the weekend, to use all week, we had 12 diesel trucks, Monday morning, I would be there as the drivers started their trucks, about 5 minutes after I heard some knocking and sounded like pre-ignition, I yelled "shut it down", then while I was checking the truck another truck started, banging and knocking, I had all the trucks shut down, as I was checking things I smelled gasoline!!!, 5 of the trucks had gasoline in the tanks, I red tagged those 5, the others I let go to work. What happened, the tanker driver put approximately 1,400 gallons gasoline, in the diesel tank, all 5 trucks were completely drained, and the fuel system's flushed, refilled with diesel, I found No Damage, But it was caught quickly, them the 5,000 gallon diesel tank had to be completely drained and refilled. Then when I was 18 years old, I took 5 gallons of diesel fuel and poured it in my 1962 Mercury Comet inline 6cyl. Carburated engine, it smoked like Hell but it ran !!!, But when I shut it off and let it cool down, it wouldn't start but it puffed out blue smoke !!! So I had to drain the tank, blow out the line and carburetor then it started again and ran fine after the cylinders cleared of diesel fuel, "Dumb Kid Stuff" 😆😆😆😆😆😆😆😆😆😆😆 Great Video nice tutorial Long Beach, California
We normally put a small amount of premium gas into our older tractors keeps it thawed at a cheaper price obviously not a 50:50 like a cup of gas for 34 gallons of diesel.
Just happened in my son's pt cruiser. The car ran like shit, it knocked and smoked and it hesitated. The car had a 1/4 of diesel fuel left in the tank. I topped the rest of it off with gasoline now the car runs fine now.
Yep. It was done in Oregon as well. I just got new injecters, filter, and line for my Civic. I thought it was the marvel mystery I would use in each tank, until I could barely keep the motor running after one fill up at the same Fred Meyer gas station I had gone to for years. White smoke all the time, chugging and missing like no tomorrow. I dumped a can of sea foam and it slightly helped, but main symptoms of misfiring and white smoke engine chugging out still happening. And this, right after a tune up !!!!
I've actually accidently put it in my Camaro before. It smoked for a while, used a little more oil. but it did run. I just drove it all out then put more gas in. It didn't hurt it. your crazy!!!
if you make a fuel mistake, Don't turn the ignition on at all. You don't want the fuel pump to run, keep the mix contained in the tank. Diesoline or Gassel anyone?.
Had that incident in Ottawa, Canada where the delivery driver put diesel in the regular gad holding tanks...quite a few cars got damaged in the process..
I know I’m commenting on a 3 year old video, but I was recently traveling for work and stopped at a BP in Virginia and the gas nozzles for regular unleaded were green and the diesel was black. So be careful if you’re stopping at a BP in Fairfield, Virginia.
I currently have a 2018 Hyundai Tucson and when I first got it a friend of mine accidentally dumped 3 gallons of diesel into the fuel tank we just topped off the tank with gasoline and drove the car and then when the tank was empty we filled it back up with gasoline never had any issues actually the car seem to run better and I got 8 more miles per gallon than normal.
Lol I just watched a video about this on project farm. Gasoline in diesel interests me more. Neither is good, but diesel in gas is easier to recover from (depending on the ratio).
I've seen gasoline engines run ok on diesel. On more than 50/50... I think it was a carburetor engine but it didn't clog any filters. It just smoked a little from the oil
When I use to work at an Infiniti dealer, we had a customer have their brand new Q50 towed into the shop because they filled their car with diesel fuel. Car was practically still new. Probably had just under 1k miles. The tech that worked on it just drained the fuel tank and changed the spark plugs and filled it with gasoline. Surprisingly it started up after several cranks. Yeah that was some crap seeing that.
My brother-in-law‘s wife did that one time to their Ford fusion put $20 worth of diesel fuel in it and quit running on her. I filled the rest of the tank with gas and got the engine started back up on brake cleans and told him don’t shut it off. Driving around for a bit and top off the tank with some more gas it was fine didn’t cause any problems with the fuel system. The car had over 450,000 km on it before it went to the junk still ran fine. On my own car I mix up a half litre transmission fluid and a half litre of diesel fuel I’ll throw it in the gas tank to clean out the fuel system and remove carbon. Never had any problems with doing that Car now has 400,000 km on it still runs fine.
I've run a car on tank drain fuel from a dealership dump tank. We called it PERV. A mix of Petrol and DERV. Ran ok, occasionally misfired then just carried on regardless. It was a small, low output engine so relatively safe, just dirty sparkplugs until you have it a good hammering
my 1.9 tdi 1z audi 80 has had 2l of petrol with every full tank of diesel for now going 400k on the same engine and fuel pump! my father has owned the car from new and i now own the 1991 aged car that is 28 years old! it has also been run on a mixture of veg oil and petrol too
but any new car with the extremely high pressure pumps would get absolutely destroyed doing this! i dont know but i think the little bit of petrol has kept the system clean over the years as the car still has most of its 90bhp from the factory and to be honest it feels like more,TO BE CLEAR HERE THE CAR HAS NEVER BEEN RUN ON JUST PETROL
In the UK we put a little gasoline in diesel tanks to stop the diesel waxing in cold weather. Now modern diesel has additives (silicone) added at the refinery in the winter to stop waxing.
We had the same exact thing happen at a gas station near me. I also work at a Toyota dealership, and we have had a couple cars come in with diesel fuel in them.
@Sean M Yes, different sizes. Almost impossible to put diesel into a petrol car because the nozzle is too big. But, all too easy to put petrol in to a diesel. A shame it is that way around because the later does so much more damage.
Gasoline in a diesel car is much, much worse :P Edit: He does address this later on in the video so my post is kinda useless. Jumped the gun too early lol. Fun trivia: Older gassers couldn't care less, they'll laugh at you and run normally on diesel as long as the engine is warm. (You'll probably damage the cat tho).
Eric already mentioned that diesel is sort of a very lightweight oil and there's the catch: modern diesel pumps or pump injectors on the engine are lubricated by the fuel they're pumping up to pressures well over 1500 bar or 20000 psi. replace that lubricant with a solvent and i guess you can imagine what'll happen, right?
@@ivokraaier9740 The fuel system is the least of your concerns if you run a diesel car on gas to give some perspective on how bad it truly is. You'll cook everything :)
Older diesel cars did recommend using petrol in the tank on occasions of deep cold when fuel gelled. Solvent properties made for great flow. Best to use kerosene, but gas, in reason, won’t destroy a real diesel. The new eco-friendly diesels fail to function well in real cold
Back in the 1940's my dad had a Plymouth pickup which he only ever ran on diesel. Because of the very limited supply of gasoline die to the depression it was severely rationed. He figured why not give it a go. It worked. He rant it daily until he died in 1972. Also he had disabled some of the cylinders by removing the exhaust valves. You could tell by how rough it ran and the lack of HT leads to the disabled cylinders. From 1967 I did the same with my old Ford Jailbar V8. Never once had a problem except it was hard to start, especially on a frosty morning. 18 years I used it daily and did many long trips too. Got 15 miles per gallon.
Back in the day when I was working in a motorcycle shop, someone filled up a bike with diesel. What a mess. Even after cleaning the tank, carburetors, and fuel lines, the bike still smoked like a chimney for about 10 minutes LOL. Years before that when I was working for a roofing company, somebody put gasoline in the brand new diesel truck they just bought. It idled at three grand for a few seconds and then that was it. Tow truck time, ha ha ha!
My friend gets gas and diesel for free from blowing tanker trailers down to weld them and he mixes 50/50 gas and diesel and puts it in his 2008 Dodge Ram hemi...he’s been doing it for more than a decade, no issues at all.
back in the 80's when gas was $.87/gallon there was a gas station in town that was putting water in the gas then cars would drive away & stall down the highway. gas station owners brother owned a towing service down the street
Ran a diesel fuel mix in my 1981 Honda accord ex (carburetted) at about a 10% mix it was fine yes it was Smokey no it wasn't ideal but no damage at least in my case one time I did run to high a mix the car stalled out and wouldn't start but once that diesel was diluted back down all was fine
For the most part....The local shell in my neighborhood actually has a separate fully black pump for diesel. This could just be a shell thing because of their corporate colors, but I don't think I've ever seen a yellow diesel pump.
One time, dad put gas in his diesel jeep when diesel was over $4/gallon... At least it wasn't a big tank. If your injectors don't get gummed up... If your sparkers still spark it... It might not be too bad. After I got gas one time, I had an OBD error the catalytic converter was bad for a while. I won't go back to that station. Just don't put DEF in your fuel.
Have had a renault kangoo here in europe (1.3 diesel) and accidently put 35 liters of gasoline in the 55 liter tank, finally noticed and topped of with diesel........drove fine, every few miles put some more diesel back in and really never had an issue because of it.......................drove fine the next 3 or 4 years
I’ve been a heavy truck tech for 15 going on 16 years and I have seen it all gas in diesel engines, diesel in gas engines and the new big this is def in the fuel tank and that is the worse of the worse.
I've been told about people mixing Diesel and petrol together for their diesel cars. Some sort of performance gain is what they did it for. I never thought it was a good idea and now I know why.
Citizen of a country where it sometimes gets stupid cold in winter (-30C what you could expect at worst). Sometimes we put a liter or two in a full tank of diesel. Why you ask? Diesel gets very viscous at those temps, so in result it does not freeze as bad and makes your morning commute not suck as bad :) . To be fair, new cars are more sensitive, so people don't really do that anymore.
Hello Eric the car guy there was an incident here in PEI Canada where a delivery guy put furnace oil in the storage tank of gasoline cause a lot of damage to a lot of vehicles about a mouth ago be well be safe
Alternative recommendation for if you're in a situtation where you can't get towed, can't drain the tank, or for any other reason are incapable of doing the correct thing to do (drain your tank and put the proper fuel back in your car). I'm talking dire straights here, out of options. If you've put diesel in a gas engine, it will not start on diesel, but if started on gasoline, the heat from gasoline combustion will help burn the diesel. If the compression ratio of the engine is low enough it will not ignite the diesel until the gasoline is burning. It is not good for your catalytic converter, O2 sensors, EGR, turbo (if equipped), fuel pump, filters, or injectors (there is more wax and contaminant in diesel than gasoline, and the unburned byproducts will find it's way to other things). That is to say, if you absolutely can not properly service the situation, if you've started your gasoline car and its running on a diesel gas mix, keep the engine running drive around gently at lower RPMs(if you hear knocking sounds its bad, reduce engine speed and load). Knocking sounds mean the diesel is combusting before the spark plug is commanding fuel ignition. Return to a fuel station, leave your engine running otherwise it will not start again on the diesel mix, keep adding gasoline to the tank until you've gotten more than half the capacity of the tank back in. This is not considered a safe practice either. When you get back to a location where you can service the vehicle, inspect and replace components.
no. It works just fine. Many use it during the winter. If you add too much I'd suggest adding some oil too to lubricate fuel pump. What's the new cetane number? I'd like this vid to be much better in explaining that
People putting petrol in their diesels is a somewhat common occurrence in the UK. Kinda worse than the diesel in petrol, tends to cause more damage due to the lack of lubricant
AliasSLH each pump in the uk has a nozzle for each type of fuel (usually) so we get basic gasoline called "unleaded" (95 RON), then we have "superunleaded" (98 RON) and if you go to shell then you also get two choices of diesel standard "low sulfur" and then v power if you want the better lubricants, higher cetane and better detergents. Having worked in the motorsport industry for 10 years using a chassis dyno and have compared many a different fuel... I would never use anything other than shells v- power.
Chemist here, some things i want to point out. Diesel and petrol have quite different physical properties, but the chemical properties are quite similar. The viscocity in diesel stems from the longer hydrocarbon chains, which also results in a higher boiling point than petrol. They are perfectly miscible because they are both very non-polar. They also have very little way of reacting with one-another because they should (in theory) have little to no reactive functional groups. According to a video of Project Farm, washing through a petrol system that was first added diesel with petrol should dilute the diesel enough to get the engine running (lower viscocity). Probably as you said because the clogging of the fuel filter and possibly injector? Other way around (adding petrol to diesel engine) should be a fun experiment though. Wonder what would happen.
My stepdad put gas in a diesel truck luckily he noticed before he started it so they got it towed from the gas station cost them around 1,200 to get it fixed
Here because I had a dream last night that I was down to 20% and accidentally topped off with diesel. In the dream my car ran just a few seconds then died. There was a service station across the street that drained the fuel completely and replaced the fuel filter and I was good. Neat that a dream would be so accurate to life.
My grandfather had an old tractor from the 30's or so, No exhaust manifolds so it was super loud, sounded like 6 shotguns firing. He would take all of the families used motor oil from oil changes, run it through a simple strainer to get out any solids or sludge, then pour it right into the tractor and ran the tractor off of the motor oil.
My buddy was using a riding lawnmower and put Diesel in the mower and started it up. The mower smoked and ran for about 5 minutes before I saw the cloud of smoke. Luckily being a small engine we cleaned the carburetor drained it put gas back in and it fired up. We nicknamed our buddy Diesel from that day on.
the Project Farm channel has gone into this subject a bit. He did testing using a carburated push mower. The engine would not run an strait diesel, but ran ok on a mix. Unfortunaltly, he did not test gas in a diesel or fuel injected engine
Diesel is a lubricant. So if you run gasoline in a modern diesel system it will trash everything. Especially the high pressure pump will grenade. Gas engine can run on diesel since diesel is about 76 octane rated...but it will run like poo.
I'm adding 5% gasoline to my diesels every time. It is even recommended by manual for winter sezon (old engines: 2.5 TDI v6 and 1.9 TDI 1Z). They have little bit more power on this mixture:)
in most tanker companies that deliver gasoline they also deliver diesel fuel and diesel fuel and gasoline are commonly mixed within the tank even though it's only a very small amount that is left in the tanker after each delivery.
Back in the day when they drove carburetor engines the old timers would actually put a gallon of diesel in with the gas on a fill up. They said it cleaned out the system and carburetor. Don't know if that's true or not
Miami Dade County Fleet had 350 vehicles damaged from diesel in gas. They even needed a bunch of engines. West Palm Beach Fleet needed 185 engines from the damage done by by diesel put in they gasoline supply. There is no safe amount of diesel in gasoline. If you put diesel in your gasoline don't drive it and have the fuel tank and lines flushed.
actually many older cars and tractors were converted to run on kerosene which is more similar to diesel than gasoline. you would start on gas, let it heat up, and then switch over to kerosene which was cheaper.
In Australia we dont have a color code for fuel. Each brand of station has their colors so if you go from shell to caltex to mobil the colors for the pumps are not the same. We have E10, 91, 95, 98, LNG/Autogas, Diesel and some places have E85 Each has its own color
Okay, this is retro as hell, but..... We use to add a gallon of diesel to the tank on a fill up occasionally. Word was that it cleaned the combustion chamber and lubricated the valves. We would also top up the oil with a quart of diesel just before an oil change run the engine to full temp at low load to remove more impurities from the crank case. I did it because my dad did it. It may have worked. I did it with a used 1964 Chevy pick-up with the 235 6 cylinder. I put 400,000 miles on it. I then sold it to a friend who drove it for 10 years, or so, and continued the diesel thing. He sold it just before he went on to the other plane. It had sat for 10 years at that point. The guy who bought brought a used battery, a fuel pump, and a rebuilt carb. It started on the third crank, ran rough for a few seconds and settled down. Then he took all four wheels off, came back with new rubber and drove away. I don't know whether it was the diesel or just how tough and forgiving those old trucks are.
My former manager would put our waste non-conductive, non-flammable silicon transformer oil in our diesel truck. I think it ran a couple of months before the engine blew up.
They put in new pumps at a local station. Kerosene was now on the same side as diesel. Tired, no coffee, didn't pay attention. Filled up one of my tanks with Kerosene before I noticed. Filled other with diesel, called ford. And they said it wasn't that big of a deal, but it was best to siphon it or drain it.
I disagree, from my experience, with gasoline in a Diesel engine. However, depends on the ratio. A couple of gallons in a 100-200 gallon tank and it’s a great injector cleaner…..even gives you a little extra short term torque. However, large diesel tanks often vent to atmosphere and the unused gas will evaporate within a few hours. The blue 2 stroke oil also works great in a modern Diesel engine
I pumped it out the old diesel. I have sludge left in my diesel truck tank. A guy said to put enough gas in to cover the sludge & it would dissolve the sludge & then drain the stuff out. Would this work?
Lol 😂 injector cleaner ! No , I suggest you pull an injector from your car and have a look at how tiny the holes are , if you have clogged injectors you need to replace them ,… no such thing as refurbishing injectors either … manufacturers recommend replacing injectors every two years ! No one does and everyone believes they can be cleaned ! All lies
Yes. In fact, in a 57 hemi Many many times i have experienced just that, I put in. As much as 1.5 gallons to 30. gallon tank of unleaded. and there is extra torque easily felt when you step in the throttle and the engine idles as smooth as it ever has, if not more. The other added benefit was. doing this. when I was going to be traveling down the highway, I gained 1.2 actual miles per gallon. which offset the expense of that gallon of diesel. I generally only use it in gasoline when it's cheaper. than it is at the pump now, but Diesel is a lubricant. These clowns don't even understand the difference. They think it's like mixing oil and water. I. never met so many clues. People. So afraid with zero understanding I'm glad I was born 55 years ago.
Gas in a diesel engine will wreck the fuel pump first which operates at extremely high pressures. The pump actually relies on the lubricity of diesel fuel to function properly. With insufficient lubrication, you can guess what happens. Quite common here in the Philippines since there are several popular utility vehicles and pick-ups that come with both diesel and gas engine variants with the only distinction being a sticker on the filler cap.
Diesel is actually a form of oil. Oil fired furnaces/boilers actually burn diesel - it's just labeled differently and has no road tax added. They dye it red so that if you are ever caught with it in a vehicle, they know it was not meant to be used on the road and you get a pretty hefty fine.
How long would a gasoline engine run if diesel was added? Sounds like a suggestion for Project Farm.
@Random Stuffs maybe I haven't seen one of the other "best" channels out there, but project farm is awesome. Not only does he test products that I use in my life, but does it in a trustworthy manner. And he's from Missouri, which is where all the cool guys live. 😎
I think Project Farm already tried this, in a lawnmower engine.
@@mattschmitt9924
Agreed, I've always appreciated PF's objectiveness and consistency in his testing methods.
i was thinking the exact same thing, time to send the suggestion!
@@mattschmitt9924 true there might be others, but PF is a huge channel by now but he still remains down to earth, reads comments and interacts and takes project feedback without gating it to "only patreons" that a lot of channel do(if you're a patron you can get to vote on teh next video, F U), his methods are also thorough and interesting
For non-catalytic engines it's been a practice of some - ever since leaded fuel went away from normal pumps I'd guess - to put a little diesel in with the gasoline fill-up as an upper-cylinder / valve lubricant. I've done this with motorcycles, older carburetor vehicles, and a fuel-injected Jeep Wrangler (inline six) that someone took the catalytic off of. They all ran great with that little bit of lube in there.
I remember when I was a kid my dad experimented with adding diesel to the gasoline in his f350 with a carbed 460. He came up with 1gallon of diesel to 10 gallons of gasoline and it actually increased the fuel economy a little and left a white coating in the pipes. Any more than that he got soot. All bets are off on a fuel injected vehicle though.
How long did that 10 gallons last?
60 miles lol?
exactly right. Now that you gave me the ratio...Im gonna use it. THANK YOU Love naturally asperated vehiclles
I'm pretty sure the carbed 460 didn't have a cat converter, FWIW.
I don't even measure what I mix. Oil, diesel, gas, lamp oil, charcoal lighter fluid, moonshine, I just throw it all in the tank and my truck keeps on running like a champ. Multi-fuels are great.
All bets are NOT off with a fuel injected vehicle! I've used it several times in several engines inluding a modified Corvette LS1. I used a far smaller ratio, like 1cup diesel to 10 gallons of gas, and had only benefits, no cat issues, soot or anything. It essentially raised the octane level and stopped some minor pinging I'd been having even with high-octane gas. High compression engine was tuned for more HP and had the timing a bit too far advanced, hence the need for more than 'premium'. Essentially high-octane is harder to ignite (or in my Corvette's case 'preignite' due to pressing the limits of timing to compression ratio). Diesel is also harder to ignite, so the effects are much the same as higher octane. It's also an upper-cylinder lubricant, similar to Lucas gas treatment. It likely won't benefit lower performance engines that are running well, just like higher octane fuel doesn't. It's a misconception that higher-octane is more 'premium', other than sometimes have more cleaning additives than 'regular'. High octane is only harder to ignite (therefore reducing preignition in vehicles that require it- typically performance engines.) Like you said, you don't want to run the ratios you mentioned in a fuel injected car, too hard to burn completely (cleanly). But in the right ratios depending on your engines tune, works great as an octane booster!
Diesel fuel as well as gasoline are both great solvents. I've noticed at my shop when we do a diesel oil change and then do fuel filters the pan will clean itself out using the diesel fuel.
Europe pumps: black pump is diesel and green pump gasoline
Honda enthusiast here..right or wrong on occasion i put .5 l of diesel in a full tank in my 20yr oldl RSX
and it runs like high test..pulls strong..been doing it for 10 yrs and over 150,000 k-
inspection camera on intakes- clean asa whistle-zero emission issues-runs like a top-and
drive the shit out of it..260k+ and i figure shes just gittin broke in..LMFAO
Eric,love your content,been subed for years,keep up the good work!
Hey Eric. I'm a Chrysler tech in Canada. Our Diesel nozzles are yellow or green, it depends in which gas station you go to.
Back to the Chrysler tech thing.. we have both diesel and gasoline powered vehicles as you would know. So we do get both sides of the equation a lot more frequently than we probably should.
Gas in Diesel vehicles doesn't seem to bother them much. We have been very lucky and only ever had to flush the fuel system out.
Diesel in gas vehicles usually goes the same way but on 2 instances.. we have actually seen 2 engines that began to Crack the crown of the pistons as a result of trying to burn the Diesel fuel.
Keep up the good work pal
My 6-year old son wanted to "help" my wife pump gas into our '95 Mazda Millennia. The car ran for 150 miles until reaching their destination. Next day, the car would not start. It was eventually diagnosed with bad fuel, tank drained, and refilled with gas. Car ran a little rough until the rest of the bad gas was out of the system. I contacted the out-of-town station about the bad gas, and after looking at the receipt, was told diesel had been pumped, maybe 1/3 to 1/2 tank.
Unfortunately, the diesel nozle was the same size as gas.
This is wat I accidentally put desiel in my dad truck and it was bad I made the same mistake
Years ago a Trucker told me he would add a gallon or 2 of gas to his Diesel Tanks when going into subzero temperatures, He said it would prevent diesel from gelling up because of the cold. I once worked fueling Diesel Locomotives in Montana, We would add a couple gallons of Alcohol during winter months, I thought that was to help the water move thru the fuel system during the winter months
Yep the diesel treatments like Hot Shot and Cetane booster...is actually a volotile fuel like gasoline.
He is absolutely correct. Unlike octane booster which makes gas ignite SLOWER, the cetane booster helps diesel ignite FASTER. Gasoline is the most economical common sense way to do so.
There have been many cars through history which had diesel and gas tanks and used gasoline mixed in at startup then switched to full diesel.
I know a guy who adds a little diesel to the tank when he fuels up his GTO. He says it raises the octant enough to stop his high compression engine from pinging. I don't remember how much he puts in (per gallon), but I know he's being doing it since he rebuilt the engine back in 2012.
YMMV!
I commented earlier, but I ran it in several modern day gas cars, including a modified (and ohh so fast) C5 Corvette (likely the same engine as your friend's, depending on his year) for the same reason. I ran about a cup per 15 gallons of premium gas. Because it was tuned, I could see on the computer that it allowed me to add more timing before any potential preignition. It also cleans and lubricates things better. I don't think it does much good for cars that don't need high octane, though.
The octane rating of diesel averages 20-30 so it would definitely lower the octane of the premium higher octane fuel it's mixed with.
I'm a heavy equipment and farm equipment mechanic and I like your videos, keep Up The good work 👍
The reason diesel is bad in gas, is that eventually the gas will separate out and sit on top of the diesel. leaving the pump sucking up a majority of diesel and a little bit of gas, so if it does run (poorly) it will do major damage with detonation. we had a Technician rev up an older engine after flushing the system out, but forgot to flush the rail so there was still diesel in the system, and it threw a piston through the block.
Great video. Very informative. One interesting thing I found out is even before refined peanut oil, Rudolf Diesel's very first attempt used coal dust as a fuel. It nearly killed him several times when the engine block exploded.
Oh wow! I remember that!
Damn. I appreciate all that. Great knowledge !
But what Im really wondering is what happens when you put decaf in regular???
Half-caff?
Depends on who you do it to. In my case , that would result in a punch in the face and a trip to the dentist. 😂
Nothing much. Lol
Total melt downs occur
Do you really want to walk through that door?
What would happen if I put Diesel in my electric car? Asking for a friend... Lol
Yeah, it's for a "friend". What'd he do to you? LOL
Small electrical short
You dont got a car is what happend!!
What, how? You know what I don't know if you should have a car at all.
How? Electric cars don’t have a gas tank or filler hole.
Few years back, a co worker put gasoline in a diesel vehicle of the company, and the result was - as Eric tells us - really bad. The car was "repaired" and ran a few hundred kilometeres, but soon enough, the car was declared dead, because is costed too much too repair it, given the mileage it had (190 thousand miles approximately)
Great video man! I've seen this happen a few times at my job both ways around - gas in a diesel and diesel in a gas. It's always a pain when they put gas in a diesel because in addition to removing all the bad fuel we need to change all the filters. And they take forever to get started again. I've never seen engine damage result from this, but that's not to say it can't happen. I have seen catalytic converters go bad on gas vehicles not long after something like this though.
Would 400 gallons of ulsd into a 17k full reg tank mess it up?
I'm wondering if you're pre-filling the new diesel filters before fitting?
In Norway Diesel filler necks are black and gasoline is green. I looked like an idiot trying to fill up the rental car first time I was in the US.
Oh my gosh! I can see it! Thanks for sharing!
The smaller gas filler neck was actually done to prevent you from putting leaded gas into your tank and killing your cat.
It's just that Diesel-fillers are still the old size bc Diesel never really changed that much. The switch to LSD in the 2000s was gradual and did not include a change in filler size.
If you let your mixture sit for a few hours, the gasoline will be the top layer and diesel on the bottom due to specific gravity.
Good or bad
not it will not. it is like mixing milk in coffee. the only process that can separate them is the distillation process as they do for crude oil. So petrol and diesel will mix together and form a blend.
Diesel into a petrol vehicle will run as you stated for a period of time but will also blow out excessive smoke out of the exhaust.
i have a 70s engine the hoses at the station were mixed up so i put diesel in it, it ran rough but still went once you got it going you could keep it going as long as the revs were up when i turned the ignition off the engine did keep running because the compression was igniting the diesel
Just siphon out as much as possible, change the fuel filter and then fill it up with gasoline. Top off the tank as often as possible. Drive it until the gas washes the diesel out. Problem solved.
In Europe Diesel pumps are marked black and Gasoline is always green - at least for the last 20+ years since we switched to unleaded. Gasoline pumps also have a much smaller spigot, so Diesel pump will not fit into the tank opening. Putting Gasoline in a Diesel is a common thing though. Modern Diesel cars seem to stop soon enough not to cause damage and the mistake costs about 4x what it costs to pump a tank of gas (1x for the gas you've put in there, 1x for the filters, 1x for service and of course you still have to fill the tank with Diesel in the end)
Decades ago I regularly added @ 10% gasoline & 90% diesel to my 1st gen Diesel Rabbit to give it a little ZIP...made it feel like it had a turbo which it didn’t. I ran it that way esp in the winter for 5 years
Back in the 70's granit haulers use to stop at a dinner in Vermont and put some gas in there trucks to lesson the fuel from gelling. That was when the temp would be well below freezing.
@@wallaceeverett3927 That is some trick I still know, and actually the only exception that allows putting gasoline into a Diesel.
As you mentioned the Diesel starts gelling below certain temperatures, after a time it really gets some kind of nasty waxy substance.
Adding at most 10 % of gasoline would actually change lower the gelling temperature and kind of disssolve the wax.
At least here in Europe, they change between what they calll summer Diesel and winter Diesel in time. Winter Diesel has additives in it that prevent Gelling down to temperatures around either -20 °C or -30 °C, can´t remember actually. I guess its the same in any part of the world that may reach critical temperatures these days.
By the way, you still can use this trick today, if you have a Diesel that gets only low miles and you put in fresh Diesel last time during the summer, just put in some Gasoline, depending on how much Diesel you have left in the tank.
Alternative method: Use a torch or make a fire beneath the engine to preheat... Lets call it the "russian way". Not sure if anything not beeing an Ural or whatever will live through or not burst into flames. With modern cars you might get a heap of burning plastic way before the engine heats up...
Welp now I can see how someone foreign is going to mix those up. In Portugal at least, gasoline is labeled in shades of green (for the several octane ratings in RON) and diesel is labeled in black
That is the same as here in Australia. When they have them alongside regular fuel pumps there is often an extra lever that needs to be pushed down to unlock the the diesel filler.
@@AndreasKoepkeAU I guess the lever is somewhat of a fool proof method. Here you have to read to be sure (aside from the labels).Gasoline usually is 95/Premium 95(Both E5 - 5% Ethanol) both in dark green or 98/Premium 98(Both E10 - 10% Ethanol) in light green. Some brands also have "premium" diesel in yellow (Both B15 - Biodiesel 15%)
NoobGamerPT americans have allways everting in reverse. Remember they use miles, gallons, inches...etc
Also, they only use diesel in SUVs and 4x4 trucks, the rest are gasoline.
Not like in europe, more than 50% of cars are diesel, even small city cars. Or at least it was before diesel gate and eletric cars start to rise.
@@sjogosPT the same team which reported on VW diesels found after that BMW's, gasoline type, also over polluted than reported. No wonder Germany is getting in trouble with the EU for emissions in some of their cities.
The very first time putting gas in my car after moving back to the states from Mexico, i do exactly that 😅 diesel in a gas car 🤦🏻♀️
I have run lawnmowers on 50/50 gas and diesel. I once ran 2 at the same time with the same fuel, one ran better than ever, and the other ran the last time ever. Both engines were healthy.
If you put petrol in a modern diesel with common rail injection and drive off, you can easily total your car.
I think the car would be fine - fuel supply line would be the issue.
That is absolutely true. Gasoline has high compression and will blow the heads off
@@mds2465 I'm sure diesel has higher compression compared to petrol.
The issue is that diesels use diesel as a lubricant and gas goes not offer the lubricity that diesel does. So the components run without lubrication, frag out, and fill the engine with metal shavings. A modern diesel fuel pump is 5000 pounds of pressure, you need that lubrication.
@@adriansrealm And usually the metal particles coming from the destroyed pump clog up the injectors...
My X-Wife put Diesel in my compressor when I was 3 stories up oon a roof it choked out and smoked like crazy ! After I drained the Diesel and put gas back in I WAS JAW DROPPED AT HOW GOOD IT RAN!!! I apologized for the choice words and insults involuntarily released in anger ( NOT INVOLUNTARY ) and told her this was the best mistake she had made that I had witnessed.
Just bought M-B CLK 320 for very cheap, because it would not start. It had missfire codes, thick gray smoke coming from exhaust etc. Then i realized that previous owner must have put diesel in it by mistake. Drained the old fuel mixture out and put 30 litres of gas in it. It started, idled roughly for few minutes and then it started running with no problems. Cheap fix.
Some BP stations have green handles on the gasoline side so be careful. I had a family member accidentally fill a diesel with the green handle and it turned out to be unleaded.
That explains why I am nervous to gas up at BP in North Carolina. The coloring is weird. I said to my friend, are you sure this is okay?
Yes, Damn BP! and there are lots of places with small fill nozzels on the diesel pumps. Some years of Chevy trucks have small fuel fills like a gasoline pump, so you have to find the small nozzels.
Duuuuude, Glad to see the vids and knowledge keep coming. Thanks for keeping me up to date on Hondas, Acuras, and cars in general. I do still refer to your videos from time to time for side work. Hope all is well in your world!!
A tiny bit of biodiesel in gas helps lubricate everything and makes engine last longer.
A much easier way is to add some type of Upper Cylinder Lubricant. I cover a few products which I've ran for years with good results. Full testing and results of multiple products can be found on my channel.
Eric, I delivered fuels for many years, both gasoline and diesel. The tanks were never washed out. However, we did load gas into the container that had diesel to cut the diesel. But then you may be talking about 3 gallons leftover mixed with 3600 gallons of gasoline.
Now deliver was extremely important. You had to be sure you loaded diesel only in a diesel tank at the stations, and the same with gasoline. 500 gallons of diesel into a 50,000 gallon tank wouldn't hurt anything much, except the driver's paycheck (which he no longer got from our company).
Now going the other direction, if gasoline was delivered into a diesel storage tank and then pumped into a diesel vehicle: NEW ENGINE. Gasoline is too volatile for use in a diesel engine. It will wreck the injectors, preheat chambers, and the fuel pump. Rings tend to crack or break off. And then the oil gets diluted seriously.

What about 400 ulsd in 17k regular tank
A colleague of mine went to refuel a Saab 9-5 petrol. He filled diesel in it and drove roughly 3-4 kilometers before the 2.3T suddenly stopped. Inspections showed there was a crack in the piston and the inspection camera went right into the oil sump. The engine ran fine before this, so we suspect it was caused by the mixing of diesel into the tank where the liquid wouldn't ignite.
Maybe due to low octane number of Diesel it was preigniting, breaking everything inside the engine
Thanks for the video. My granddaughter managed to put 9.5 gallons of diesel in her car with an 18.5 gallon tank (gasoline car). Needless to say, once the mixture in the tank reached the engine it quit running. Once I figured out what happened, I siphoned out all the fuel I could get and filled the tank up with gasoline. After several tries and spraying ether in the intake manifold, we finally got the engine running fine. The check engine light is on now but I won’t be able to read the error code for a couple of days. Hopefully it will just be an error that needs to be reset with an obd2 reader.
Error code was a misfire in cylinder #3. It cleared and everything is aok now.
You're obviously referring to an older carburetted vehicle. because any new vehicle has a small neck and won't allow the diesel fuel. nozzle. into the tank, In that case, yes, in a carburetted engine, it would not run well at that mixture., in a few injected engine. However, it has no choice but to get injected and burned. and it will end of story. Injectors don't care
It’s extra awesome when your delivery guy puts a couple hundred gallons of diesel in one of your tanks (ended up being around 30% diesel) and doesn’t tell you. We’re a fleet station and chased this problem for 2 weeks before I discovered what happened. I imagine there will be a lot of o2 and catalyst problems in our future. Changed a TON of plugs so far. Also can’t wait to see what possible side effects the diesel has had on any of the rubber or synthetic rubber components.
I mixed 400 ulsd in regular tank at full capacity of 17k. My company fired me they said they had to pump all 17k gallons out?
So I'm heavy equipment diesel mechanic and for about 4 years I ran a 50-50 mix premium gasoline and pump grade on road diesel in my 1993 Isuzu rodeo 3.2 l V6 did not notice any lack of power never had issues with injectors filters pumps etc like I said I done this for years The one downside was my vehicle smell like a diesel and older diesel it wouldn't roll call but you definitely had some unburned diesel smell on the exhaust this engine is still running today The rig is now a play toy 360 plus thousand miles and doesn't hiccup runs flawlessly
I was a mechanic in the 60's, to 80's, where I worked, there was a 5,000 gallon diesel tank that would get filled on the weekend, to use all week, we had 12 diesel trucks, Monday morning, I would be there as the drivers started their trucks, about 5 minutes after I heard some knocking and sounded like pre-ignition, I yelled "shut it down", then while I was checking the truck another truck started, banging and knocking, I had all the trucks shut down, as I was checking things I smelled gasoline!!!, 5 of the trucks had gasoline in the tanks, I red tagged those 5, the others I let go to work. What happened, the tanker driver put approximately 1,400 gallons gasoline, in the diesel tank, all 5 trucks were completely drained, and the fuel system's flushed, refilled with diesel, I found No Damage, But it was caught quickly, them the 5,000 gallon diesel tank had to be completely drained and refilled. Then when I was 18 years old, I took 5 gallons of diesel fuel and poured it in my 1962 Mercury Comet inline 6cyl. Carburated engine, it smoked like Hell
but it ran !!!, But when I shut it off and let it cool down, it wouldn't start but it puffed out blue smoke !!!
So I had to drain the tank, blow out the line and carburetor then it started again and ran fine after the cylinders cleared of diesel fuel, "Dumb Kid Stuff" 😆😆😆😆😆😆😆😆😆😆😆
Great Video nice tutorial
Long Beach, California
We normally put a small amount of premium gas into our older tractors keeps it thawed at a cheaper price obviously not a 50:50 like a cup of gas for 34 gallons of diesel.
Just happened in my son's pt cruiser. The car ran like shit, it knocked and smoked and it hesitated. The car had a 1/4 of diesel fuel left in the tank. I topped the rest of it off with gasoline now the car runs fine now.
Yep. It was done in Oregon as well. I just got new injecters, filter, and line for my Civic. I thought it was the marvel mystery I would use in each tank, until I could barely keep the motor running after one fill up at the same Fred Meyer gas station I had gone to for years. White smoke all the time, chugging and missing like no tomorrow. I dumped a can of sea foam and it slightly helped, but main symptoms of misfiring and white smoke engine chugging out still happening. And this, right after a tune up !!!!
I've actually accidently put it in my Camaro before. It smoked for a while, used a little more oil. but it did run. I just drove it all out then put more gas in. It didn't hurt it. your crazy!!!
if you make a fuel mistake, Don't turn the ignition on at all.
You don't want the fuel pump to run, keep the mix contained in the tank.
Diesoline or Gassel anyone?.
Probably the best advice. Thanks for the comment.
odd, in the UK we have the pump colours reversed, petrol (gas) is always green and diesel is black, and that applies to fuel cans as well
Had that incident in Ottawa, Canada where the delivery driver put diesel in the regular gad holding tanks...quite a few cars got damaged in the process..
I know I’m commenting on a 3 year old video, but I was recently traveling for work and stopped at a BP in Virginia and the gas nozzles for regular unleaded were green and the diesel was black.
So be careful if you’re stopping at a BP in Fairfield, Virginia.
I currently have a 2018 Hyundai Tucson and when I first got it a friend of mine accidentally dumped 3 gallons of diesel into the fuel tank we just topped off the tank with gasoline and drove the car and then when the tank was empty we filled it back up with gasoline never had any issues actually the car seem to run better and I got 8 more miles per gallon than normal.
good for yoú
Lol I just watched a video about this on project farm. Gasoline in diesel interests me more.
Neither is good, but diesel in gas is easier to recover from (depending on the ratio).
I've seen gasoline engines run ok on diesel. On more than 50/50... I think it was a carburetor engine but it didn't clog any filters. It just smoked a little from the oil
@@KLMALLENDER
It probably was much worse than I thought it was.
When I use to work at an Infiniti dealer, we had a customer have their brand new Q50 towed into the shop because they filled their car with diesel fuel. Car was practically still new. Probably had just under 1k miles. The tech that worked on it just drained the fuel tank and changed the spark plugs and filled it with gasoline. Surprisingly it started up after several cranks. Yeah that was some crap seeing that.
Non car people don't deserve nice cars
Gustavo Castillo not even that. How can you be so ignorant and not be able to distinguish gasoline from diesel?
Random Stuffs that is the world we live in unfortunately
My brother-in-law‘s wife did that one time to their Ford fusion put $20 worth of diesel fuel in it and quit running on her. I filled the rest of the tank with gas and got the engine started back up on brake cleans and told him don’t shut it off. Driving around for a bit and top off the tank with some more gas it was fine didn’t cause any problems with the fuel system. The car had over 450,000 km on it before it went to the junk still ran fine. On my own car I mix up a half litre transmission fluid and a half litre of diesel fuel I’ll throw it in the gas tank to clean out the fuel system and remove carbon. Never had any problems with doing that Car now has 400,000 km on it still runs fine.
I've run a car on tank drain fuel from a dealership dump tank. We called it PERV. A mix of Petrol and DERV.
Ran ok, occasionally misfired then just carried on regardless. It was a small, low output engine so relatively safe, just dirty sparkplugs until you have it a good hammering
my 1.9 tdi 1z audi 80 has had 2l of petrol with every full tank of diesel for now going 400k on the same engine and fuel pump! my father has owned the car from new and i now own the 1991 aged car that is 28 years old! it has also been run on a mixture of veg oil and petrol too
but any new car with the extremely high pressure pumps would get absolutely destroyed doing this! i dont know but i think the little bit of petrol has kept the system clean over the years as the car still has most of its 90bhp from the factory and to be honest it feels like more,TO BE CLEAR HERE THE CAR HAS NEVER BEEN RUN ON JUST PETROL
In the UK we put a little gasoline in diesel tanks to stop the diesel waxing in cold weather. Now modern diesel has additives (silicone) added at the refinery in the winter to stop waxing.
As a technician I've ran into that some after draining the diesel and adding gas it took a while to start but when it did it smoked like crazy
We had the same exact thing happen at a gas station near me. I also work at a Toyota dealership, and we have had a couple cars come in with diesel fuel in them.
In the UK the unleaded is green..and diesel is black!
Random
Yep, one for us Brit's to take note of if we go to the states, or visa-versa!
Diesel is yellow in Canada.
@Sean M Yes, different sizes. Almost impossible to put diesel into a petrol car because the nozzle is too big. But, all too easy to put petrol in to a diesel. A shame it is that way around because the later does so much more damage.
4*/LRP was red.
@Sean M Diesel and petrol pumps have different size nozzles to prevent misfuelling. But you can't fix stupid people who will try to FORCE it
Gasoline in a diesel car is much, much worse :P
Edit: He does address this later on in the video so my post is kinda useless. Jumped the gun too early lol.
Fun trivia: Older gassers couldn't care less, they'll laugh at you and run normally on diesel as long as the engine is warm. (You'll probably damage the cat tho).
Random Stuffs 😂😂😂
Eric already mentioned that diesel is sort of a very lightweight oil and there's the catch: modern diesel pumps or pump injectors on the engine are lubricated by the fuel they're pumping up to pressures well over 1500 bar or 20000 psi. replace that lubricant with a solvent and i guess you can imagine what'll happen, right?
@@ivokraaier9740 The fuel system is the least of your concerns if you run a diesel car on gas to give some perspective on how bad it truly is. You'll cook everything :)
@@Chriva bearings don't like to be spun degreased huh. I'll have plenty of time to sort the commonrail while I'm rebuilding the donk.
@@Chriva experience?
Older diesel cars did recommend using petrol in the tank on occasions of deep cold when fuel gelled. Solvent properties made for great flow. Best to use kerosene, but gas, in reason, won’t destroy a real diesel. The new eco-friendly diesels fail to function well in real cold
Pilot injection helps cold starts
Sea Foam works great for anti gel
Engine will run just smoke a lot you keep putting gas in and it cleans up. Did it in a durango magnum 5.2 no issues after it burned out the diesel.
Back in the 1940's my dad had a Plymouth pickup which he only ever ran on diesel. Because of the very limited supply of gasoline die to the depression it was severely rationed. He figured why not give it a go. It worked. He rant it daily until he died in 1972. Also he had disabled some of the cylinders by removing the exhaust valves. You could tell by how rough it ran and the lack of HT leads to the disabled cylinders. From 1967 I did the same with my old Ford Jailbar V8. Never once had a problem except it was hard to start, especially on a frosty morning. 18 years I used it daily and did many long trips too. Got 15 miles per gallon.
Wonderful and informative video Eric, Also Your Work bench! Looks so Clean! :)
Back in the day when I was working in a motorcycle shop, someone filled up a bike with diesel. What a mess. Even after cleaning the tank, carburetors, and fuel lines, the bike still smoked like a chimney for about 10 minutes LOL. Years before that when I was working for a roofing company, somebody put gasoline in the brand new diesel truck they just bought. It idled at three grand for a few seconds and then that was it. Tow truck time, ha ha ha!
My friend gets gas and diesel for free from blowing tanker trailers down to weld them and he mixes 50/50 gas and diesel and puts it in his 2008 Dodge Ram hemi...he’s been doing it for more than a decade, no issues at all.
back in the 80's when gas was $.87/gallon there was a gas station in town that was putting water in the gas then cars would drive away & stall down the highway. gas station owners brother owned a towing service down the street
Ran a diesel fuel mix in my 1981 Honda accord ex (carburetted) at about a 10% mix it was fine yes it was Smokey no it wasn't ideal but no damage at least in my case one time I did run to high a mix the car stalled out and wouldn't start but once that diesel was diluted back down all was fine
In Ontario (maybe the rest of Canada as well) diesel dispensers are yellow and gasoline colour depends on the brand (if my memory serves me correctly)
For the most part....The local shell in my neighborhood actually has a separate fully black pump for diesel. This could just be a shell thing because of their corporate colors, but I don't think I've ever seen a yellow diesel pump.
@@skifree0 I usually get my gas at Pioneer or Mobil. I might have a look around at other stations just out of curiosity.
One time, dad put gas in his diesel jeep when diesel was over $4/gallon... At least it wasn't a big tank.
If your injectors don't get gummed up... If your sparkers still spark it... It might not be too bad.
After I got gas one time, I had an OBD error the catalytic converter was bad for a while. I won't go back to that station.
Just don't put DEF in your fuel.
Have had a renault kangoo here in europe (1.3 diesel) and accidently put 35 liters of gasoline in the 55 liter tank, finally noticed and topped of with diesel........drove fine, every few miles put some more diesel back in and really never had an issue because of it.......................drove fine the next 3 or 4 years
I’ve been a heavy truck tech for 15 going on 16 years and I have seen it all gas in diesel engines, diesel in gas engines and the new big this is def in the fuel tank and that is the worse of the worse.
DEF is Diesel Exhaust Fluid. For those of us that don't do diesels.
Yikes. DEF in the diesel tank?
I've been told about people mixing Diesel and petrol together for their diesel cars. Some sort of performance gain is what they did it for.
I never thought it was a good idea and now I know why.

Citizen of a country where it sometimes gets stupid cold in winter (-30C what you could expect at worst). Sometimes we put a liter or two in a full tank of diesel. Why you ask? Diesel gets very viscous at those temps, so in result it does not freeze as bad and makes your morning commute not suck as bad :) . To be fair, new cars are more sensitive, so people don't really do that anymore.
Thanks for getting to the point and telling us what we came to hear. Other RUclipsrs could take a lesson from you.
Hello Eric the car guy there was an incident here in PEI Canada where a delivery guy put furnace oil in the storage tank of gasoline cause a lot of damage to a lot of vehicles about a mouth ago be well be safe
Alternative recommendation for if you're in a situtation where you can't get towed, can't drain the tank, or for any other reason are incapable of doing the correct thing to do (drain your tank and put the proper fuel back in your car). I'm talking dire straights here, out of options. If you've put diesel in a gas engine, it will not start on diesel, but if started on gasoline, the heat from gasoline combustion will help burn the diesel. If the compression ratio of the engine is low enough it will not ignite the diesel until the gasoline is burning. It is not good for your catalytic converter, O2 sensors, EGR, turbo (if equipped), fuel pump, filters, or injectors (there is more wax and contaminant in diesel than gasoline, and the unburned byproducts will find it's way to other things). That is to say, if you absolutely can not properly service the situation, if you've started your gasoline car and its running on a diesel gas mix, keep the engine running drive around gently at lower RPMs(if you hear knocking sounds its bad, reduce engine speed and load). Knocking sounds mean the diesel is combusting before the spark plug is commanding fuel ignition. Return to a fuel station, leave your engine running otherwise it will not start again on the diesel mix, keep adding gasoline to the tank until you've gotten more than half the capacity of the tank back in. This is not considered a safe practice either. When you get back to a location where you can service the vehicle, inspect and replace components.
I'd rather end up with diesel in a gas engine than gas in a diesel, especially the newer ones, you'll ruin some EXPENSIVE parts!
no. It works just fine. Many use it during the winter. If you add too much I'd suggest adding some oil too to lubricate fuel pump. What's the new cetane number? I'd like this vid to be much better in explaining that
People putting petrol in their diesels is a somewhat common occurrence in the UK.
Kinda worse than the diesel in petrol, tends to cause more damage due to the lack of lubricant
Not only lack, but also breaks apart all kinds of materials in your engine. Gasket included (if it's not metal or old school carbon).
AliasSLH each pump in the uk has a nozzle for each type of fuel (usually) so we get basic gasoline called "unleaded" (95 RON), then we have "superunleaded" (98 RON) and if you go to shell then you also get two choices of diesel standard "low sulfur" and then v power if you want the better lubricants, higher cetane and better detergents.
Having worked in the motorsport industry for 10 years using a chassis dyno and have compared many a different fuel... I would never use anything other than shells v- power.
Think you got that wrong why around pal , petrol in a diesel vehicle is much much worse than the other way round.
@@andynaylor3392Literally what I said
I always knew not to mix them but never why. Thanks for the explanation
Chemist here, some things i want to point out.
Diesel and petrol have quite different physical properties, but the chemical properties are quite similar. The viscocity in diesel stems from the longer hydrocarbon chains, which also results in a higher boiling point than petrol. They are perfectly miscible because they are both very non-polar. They also have very little way of reacting with one-another because they should (in theory) have little to no reactive functional groups.
According to a video of Project Farm, washing through a petrol system that was first added diesel with petrol should dilute the diesel enough to get the engine running (lower viscocity). Probably as you said because the clogging of the fuel filter and possibly injector?
Other way around (adding petrol to diesel engine) should be a fun experiment though. Wonder what would happen.
My stepdad put gas in a diesel truck luckily he noticed before he started it so they got it towed from the gas station cost them around 1,200 to get it fixed
Here because I had a dream last night that I was down to 20% and accidentally topped off with diesel. In the dream my car ran just a few seconds then died. There was a service station across the street that drained the fuel completely and replaced the fuel filter and I was good. Neat that a dream would be so accurate to life.
My grandfather had an old tractor from the 30's or so, No exhaust manifolds so it was super loud, sounded like 6 shotguns firing. He would take all of the families used motor oil from oil changes, run it through a simple strainer to get out any solids or sludge, then pour it right into the tractor and ran the tractor off of the motor oil.
My buddy was using a riding lawnmower and put Diesel in the mower and started it up. The mower smoked and ran for about 5 minutes before I saw the cloud of smoke. Luckily being a small engine we cleaned the carburetor drained it put gas back in and it fired up. We nicknamed our buddy Diesel from that day on.
the Project Farm channel has gone into this subject a bit. He did testing using a carburated push mower. The engine would not run an strait diesel, but ran ok on a mix. Unfortunaltly, he did not test gas in a diesel or fuel injected engine
There are some places here in Canada were the diesel nozzle is yellow.
Diesel is a lubricant. So if you run gasoline in a modern diesel system it will trash everything. Especially the high pressure pump will grenade.
Gas engine can run on diesel since diesel is about 76 octane rated...but it will run like poo.
I'm adding 5% gasoline to my diesels every time. It is even recommended by manual for winter sezon (old engines: 2.5 TDI v6 and 1.9 TDI 1Z). They have little bit more power on this mixture:)
in most tanker companies that deliver gasoline they also deliver diesel fuel and diesel fuel and gasoline are commonly mixed within the tank even though it's only a very small amount that is left in the tanker after each delivery.
Back in the day when they drove carburetor engines the old timers would actually put a gallon of diesel in with the gas on a fill up. They said it cleaned out the system and carburetor. Don't know if that's true or not
Miami Dade County Fleet had 350 vehicles damaged from diesel in gas. They even needed a bunch of engines. West Palm Beach Fleet needed 185 engines from the damage done by by diesel put in they gasoline supply. There is no safe amount of diesel in gasoline. If you put diesel in your gasoline don't drive it and have the fuel tank and lines flushed.
actually many older cars and tractors were converted to run on kerosene which is more similar to diesel than gasoline. you would start on gas, let it heat up, and then switch over to kerosene which was cheaper.
In Australia we dont have a color code for fuel.
Each brand of station has their colors so if you go from shell to caltex to mobil the colors for the pumps are not the same.
We have E10, 91, 95, 98, LNG/Autogas, Diesel and some places have E85
Each has its own color
That's sounds better.
People learn to actually pay attention to what they're doing instead of just assuming.
@@HocchanFan I guess but if you go to a station brand you dont go to(say on a trip) having a set color for 95octane is a good thing.
@@IIGrayfoxII Or you could just look for the one that says 95 and use that.
@@HocchanFan That means you have to pull right up and if it is E10 trash and 98 you have to then back out and go to the drive to the next pump
Okay, this is retro as hell, but..... We use to add a gallon of diesel to the tank on a fill up occasionally. Word was that it cleaned the combustion chamber and lubricated the valves. We would also top up the oil with a quart of diesel just before an oil change run the engine to full temp at low load to remove more impurities from the crank case.
I did it because my dad did it. It may have worked. I did it with a used 1964 Chevy pick-up with the 235 6 cylinder. I put 400,000 miles on it. I then sold it to a friend who drove it for 10 years, or so, and continued the diesel thing. He sold it just before he went on to the other plane. It had sat for 10 years at that point. The guy who bought brought a used battery, a fuel pump, and a rebuilt carb. It started on the third crank, ran rough for a few seconds and settled down. Then he took all four wheels off, came back with new rubber and drove away. I don't know whether it was the diesel or just how tough and forgiving those old trucks are.
My former manager would put our waste non-conductive, non-flammable silicon transformer oil in our diesel truck. I think it ran a couple of months before the engine blew up.
They put in new pumps at a local station. Kerosene was now on the same side as diesel. Tired, no coffee, didn't pay attention. Filled up one of my tanks with Kerosene before I noticed. Filled other with diesel, called ford. And they said it wasn't that big of a deal, but it was best to siphon it or drain it.
I disagree, from my experience, with gasoline in a Diesel engine. However, depends on the ratio.
A couple of gallons in a 100-200 gallon tank and it’s a great injector cleaner…..even gives you a little extra short term torque. However, large diesel tanks often vent to atmosphere and the unused gas will evaporate within a few hours.
The blue 2 stroke oil also works great in a modern Diesel engine
I pumped it out the old diesel. I have sludge left in my diesel truck tank. A guy said to put enough gas in to cover the sludge & it would dissolve the sludge & then drain the stuff out. Would this work?
Lol 😂 injector cleaner ! No , I suggest you pull an injector from your car and have a look at how tiny the holes are , if you have clogged injectors you need to replace them ,… no such thing as refurbishing injectors either … manufacturers recommend replacing injectors every two years ! No one does and everyone believes they can be cleaned ! All lies
Yes. In fact, in a 57 hemi Many many times i have experienced just that, I put in. As much as 1.5 gallons to 30. gallon tank of unleaded. and there is extra torque easily felt when you step in the throttle and the engine idles as smooth as it ever has, if not more. The other added benefit was. doing this. when I was going to be traveling down the highway, I gained 1.2 actual miles per gallon. which offset the expense of that gallon of diesel. I generally only use it in gasoline when it's cheaper. than it is at the pump now, but Diesel is a lubricant. These clowns don't even understand the difference. They think it's like mixing oil and water. I. never met so many clues. People. So afraid with zero understanding I'm glad I was born 55 years ago.
Gas in a diesel engine will wreck the fuel pump first which operates at extremely high pressures. The pump actually relies on the lubricity of diesel fuel to function properly. With insufficient lubrication, you can guess what happens. Quite common here in the Philippines since there are several popular utility vehicles and pick-ups that come with both diesel and gas engine variants with the only distinction being a sticker on the filler cap.
Diesel is actually a form of oil. Oil fired furnaces/boilers actually burn diesel - it's just labeled differently and has no road tax added. They dye it red so that if you are ever caught with it in a vehicle, they know it was not meant to be used on the road and you get a pretty hefty fine.
Respect the beard.
