Marvels the original Gangster of oil additives!
Thx 4 sharing. I bought mmo today
@@dannyrichards6233 have you used it yet? My 99 Isuzu Rodeo has been sitting for 10 months and I'm trying to figure out if I should just do a basic oil change or add a quart of MMO
@@williamperri3437 use it just as the bottle says, replace 20% of your oil with MMO (one quart of MMO if your car takes 5 quarts). I would go 1500 miles and change it again, MMO is a very good cleaner. Too good sometimes, it can knock loose sludge and clog your oil pickup screen. Change it early and you'll be golden.
I've been adding MMO to my coffee for years, really helps clear out sludge and buildup.
I use it in my bong. Great flavor and gets you where you need to be
lol
I've been using it for enemas and boy, let me tell you, talk about being regular
@@chrisward4576 a little too regular perhaps? LOL
Lol
I used MMO on a Chevette that I bought cheap because it had a misfire once warmed up. Th engine would idle and pick up the cylinders that were misfiring. I put a can of MMO in the crankcase and drove the car as much as I dared. It was after a few drives around town that the misfires stopped. The valves were sticking when the engine warmed up and the MMO cleaned the valves to where there was no more misfire. I changed the oil and it was black. Refilled with the proper amount but substituted a can of MMO for the last quart. It desludged the engine quite nicely. My dad was a firm believer and after that, I am too...
@Sam Lester on that car, I put it in just before the oil change on 2 occasions. After that point, I put in 1/2 qt in at each oil change.
Never used it in any of my cars/trucks, but my Auto Body teacher back in 1977 told us to use it in our air tools. I've been using MMO since I graduated from Tech School in 1979. I used at least 3 of my air tools for 35 years on an almost daily basis with no problems and never needed rebuilding. Retired now and still use those 3 air tools in my garage for projects. Good stuff!
My 99 Isuzu Rodeo has been sitting for 10 months. What do you think I should do? Do you think I should do a oil change and add one quart of MMO? Any other suggestions?
@@williamperri3437
As I stated I've never used MMO in a car/truck, so I'm not positive about the results.
First, make sure the engine isn't locked-up. Socket or wrench on crank pully (bottom pully.) and see if it turns. If it turns, you're good to go. Check battery, oil change and check air filter.
This is up to you, pump out old gas or just try to run it. 10 months isn't that old......
Get rid of old gas, disconnect fuel line at engine and turn key to pump out old fuel. Add new gas and continue to pump gas through until new gas is coming out. Reconnect fuel line.
Good luck.
@@Mark-lq3sb they make MMO air tool oil now
@@williamperri3437 what did you end up doing? I'd give advice but, it's 2 late now. I've only used it for maintenance myself. But, I had some speculative ideas. For the future MMO does act as a gas stabilizer so, I'd say add it to the gas and even oil if you suspect you aren't using a car much. And use as tthin synthetic oil as your allowed. Just so it flows better. Assuming you have winter. If not than just use whatever the car asks for (upgrade to synthetic) my car seems to like Valvoline, and warren distributions which is the same brand Amazon and many other generics use. Their 0w20 works very well in winter. Actually this winter I mixed 0w16 with the 0w20 and the car started way better in the cold. Also, MMO ahas a synthetic version now. But it's not for the gas. I won't use the. Synthetic version since my car doesn't need synthetic anyway. I use use regular synthetic oil (cheapest stuff) bec it's so cheap. These days.
@@Sublimer79 I've been using MMO as a fuel additive but did not drain the old fuel. When I checked the oil it wasn't that dirty and I was going to drain a quart of oil and add the MMO but my mechanic agreed with me that I should add a half a quart or a quart to my next Oil Change which is about to happen on Tuesday. The rodeo has been running great! No valve tap and I'm getting average mpg. I added Berryman chemtool to my last 2000 passport which is basically the same vehicle and actually got just over 20 MPG. Right now I'm stuck just below 15 after about my my 10th fuel up so I'm going to try to figure that out. Ideally I would like to be getting around town at least 15 to 17. 12 to 14.6 isn't that bad! For a rodeo!
OLD mechanic here 50 years ago I found out about marvel oil from a old farmer when I purchased a Farmall tractor that had been sitting in his field for years. I asked him if he thought it would turn over.He said "no problem I have Marvel in the gas." WE pulled the plugs dumped some Marvel down the holes and it set for a couple of days till I could get back out with my trailer and battery. Turned it over with the plugs out a couple of times drained the marvel loaded gas added new and fired it up. So for 50+ years I have used marvel in the gas in most everything even my Harley. Don't own anything newer then 1998 but don't need to they all still run.

If ur car burns oil, clean the combustion chamber every once and a while ( ever 1000 miles) with MMO added in the gas. It does make a lasting difference in term of smoothness and power! I use it in everything from work vans to my own high mileage cars. Ps- I'm not promoting the use of MMO, I just want to tell someone that it works. That's it.
I use it everywhere and for over 30 years. You can even polish chrome using 0000 steel wool and MMO.
Thank you!
Noticed sludge in a friends Chevy 350 engine. Told him to add some MMO to his oil change and run it awhile. He called me a week later and was freaked out at all the sludge suspended in his engine oil. He changed and really freaked out. Tons of chunks and grime! Cleaned the engine up nicely. Sold him on it for good…. 👍
How long he run it before changing
@@handsfree3221 bout a week but he was driving quite a bit every day. I use some occasionally in my vehicles to this day, I’ll just add a quart bout 500 miles before oil change and run it. 👍
MMO is not for lowering viscosity or resisting wear. MMO cleans. I bought a car that blew smoke at every startup. I changed the oil and added half a bottle of MMO. 1000 miles later, the oil was black, the filter was heavy, and no more blow by. I used a quarter in each of the following two oil changes. After that, just regular oil changes. Car never blew smoke again. I have a spray bottle with a quart of used motor oil, half a quart of MMO, and a shot of Acetone. Amazing penetrating oil / rust remover.
I can relate this with certainty. Have a Scotts mower with a 16hp engine that started knocking really badly, didn't sound like a main bearing, more like an issue with the valves. While I started looking for another mower I thought what the heck, I'll throw some MMO in with the gas and see what happens. In around 15 minutes the noise went away. Like totally. This happened 3 more times, normally after long periods of non use. I can only guess whatever the issue was with the valves, the MMO took care of it.
Possibly carbon bouncing on a piston?Watched a mechanic diagnose the noise (sounded like a rod knock) he said it didn’t sound right. Used water, pouring it into the carburetor and the noise disappeared. He said the steam generated by the combustion in the cylinder broke down the piece of carbon soy it could pass the valve. That was one happy customer and a very wise honest mechanic.
A half a pint of MMO to every other full tank of gas works great. Been doing so since the 1980’s. Helps prevent any neoprene/rubber gas lines from drying out too.
I can't believe I saw that!! I always wondered if MMO caused more sheer, but it helps flow and sheer, and not to mention I've had a lot of success with lifter tick due to it's cleaning ability.
For the noise to the lifts must be added to the engine oil ?
@@r.s.1381 yes, to the oil.
My grandfather taught me to use MMO on my first car in 1967. MMO down the carb while its running. When the car started really smoking shut it down over night and then run it on the highway. It removed a lot of carbon in the combustion chambers. MMO in the gas and with time it cleaned the combustion chamber, valves, pistons, and piston rings. This gave the engine more power and reduced smoking. For small engines it does the same things and reduces corrosion in the fuel system over winter. I used to buy it by the case but it does't go on sale anymore.
will try this on my 87 ElCo... used to do it with seafoam $$$$
@@bigglefty75 I've never tried seafoam. I've been happy with MMO and its a lot cheaper. Good Luck, Rick
When I took over the small engine maintenance at work I started using MMO in the fuel and oil of all of our equipment. They guys all call me the "machine whisperer" now, cause things are always running right.
Lmao
How do compare to seafoam
@@henrywal completely different use case between Seafoam and MMO. MMO isn’t as good a carbon solvent, that however means you can run it every gas tank and not worry about it causing issues with gaskets. MMO is primarily a fuel based lubricant with solvent qualities.
I started using MMO in my 2012 Ford Focus (manual transmission) and with the first use my fuel mileage increased significantly. In the summer, it went from 32 - 36 mpg to 36 - 41 mpg, both in mixed driving. In the winter it went from 28 - 34 mpg to 32 - 36 mpg. I am a believer. My car today has 150,000 miles on it. I started using it around 120,000 miles. I've always changed the oil on schedule, and the engine still runs like new.
I worked in a Woodshop that had over 65 woodworkers & specialty cabinet builders from 1991 - 1996. We built women's clothing stores and sent them all over the world. Some of our stores were Lord & Taylor, The Body Shop, The Dress Barn, Macy's, The Saint Louis Science Center and many more. The ONLY oil we would use on our high speed router bearings was, Marvel Mystery Oil. That stuff is fantastic!
I personally mix a little motorkote with it. The two together, I believe is some of the best anti-friction oil that you can have for high speed bearings. I use this mixture in my vintage fans that I rebuild.
I also use a little in my car.
Ive used MMO for about 20 or so years now with no issues in all of my vehicles. My oldest being a 88 toyota is still running well with the original motor and has nearly 450k miles..
Only 20% of the longevity credit goes to MMO the rest is cause its a toyota
I believe it. I use it on the Toyota we have. Has 186k now. Been using it its whole life. Not one issue.
What engine family is that Toyota? 4 or 6 ? Cubic Inches?
@@tinamcgarrah7794 it would be the 22R-E 2.4 liter 4 cylinder engine with a 5 speed transmission. She is still running strong
@@Mr.SparkleOG oh that's the really good one, I always see on the rebuild and customize shows, they want a 22-R engine. Probably outlast some of the bodies thier in...Long Live Internal Combustion Engines!
I had lifters sticking in my Sierra, tried a couple things, changed the oil a couple times in a month, nothing helped.. Changed oil with 4 quarts oil and 1 quart MMO and within a couple days sticking lifters were gone and never had another problem.
You be the judge.
It works just note it thins oil out some. Instead of using whatever your vehicle requires go up to next viscosity 5w20 id use 5w30. You use 5w30 what my vehicle requires i stepped it up to 10w40 sense all i use is conventional oil.
Nothing in a can will repair a engine component fault..and if you think the problem was resolved with a can of cooking oil the problem will be back...fix it right the first time!! Don't let the placebo affect brain wash you!?
@@mikesecondo2254 false
@@mikesecondo2254 if a lifter is stuck, it's not broken, simply clogged up. I agree, alot of people here are just using it as a bandaid. But this sierra story, that is not the case
@@Maroco918 who said anything about being broke??!!!!!!!
Had a 350 in my Camaro, had it rebuilt, used mmo oil in crankcase only one Quart plus 4 quarts regular and put it in fuel tank regularly, when builder pulled it apart to stroke it , he said it was the cleanest internals he ever saw. The engine had 60 k on it and ran it hard. I’m sold.
Thanks for another great video, Nate. Very convincing results on the flow test and the wear test. I'm a believer now!
I have a 1948 b model John Deere tractor. It’s 74 years old and is in use now.
I dismantled the engine for its first rebuild ever in 2005.
The bearings were plasti-gauged to check wear after 57 years of service.
Rod bearings measured .006 and .005 of clearance
When New was clearance close to .004
Mains were close to same , these are shimmed bearings , one or 2 bearing shims were removed to tighten clearance to .004
This old engine must have had over 10,000 hours or more on it .
The engine as rebored , and required a unbelievable 090 overbore to get the grooves out . Guys that is so loose I’m amazed that it still started and ran ,much less run reliably.
Pa always put , Shell 30# non-detergent and Marvel in the oil
It is found in many big retailers by the gallon that knocks down a bit over the plastic bottles.
The JD was fully restored and motor restored to better than new horsepower.
Great grand kids have taken a shine to it who knows , maybe we will shoot for a 100 year service record.
Wow that's a really incredible story. I appreciate you taking time to share your experience.
I use it in my gas and synthetic 5w30 oil in my 2013 modded mustang gt 5.0 94 k and the engine is spotless .
Your comment was right on time. Changing oil tomorrow on my 2013 base and wanted to go back to using it. I did use it in previous cars, but never on this one. This was right on time!
Been using MMO for 20+ years. Every other oil change I'll use it as a replacement for 20% of motor oil and it has always seemed to do a great job. Even to the point when I do my 5k mile oil change the oil is still fairly new looking. I also add 4oz everytime I fill up with gas.
Both my cars are 23 years old and both run like new. 2K Corolla w/ 285,443mi
and a 2K Buick LeSabre w/188,502mi.
The Rola burns about a half quart of oil every 800 miles or so but this is a common issue with the 1ZZ engines Id be willing to bet it would burn much more if not for the MMO I use.
MMO reduces the viscosity of the oil and the reason it "wins" the pour test.
Yes but it was also at freezing so this is a good alternative vs using a thinner oil in winter.
Check out new oil testing never seen before ruclips.net/video/8GMw6p6-UTI/видео.html
We ran it in light aircraft engines for years. Repairs and prevents sticking valves.
One rebuilder used STP for valve guide lube and had lots of sticking valves MMO fixed every one.
Because that's the difference between Peanut Butter and sewing machine oil. STP, as I can see, is only for an old rattling worn out engine or maybe as a lighter than regular EP assembly lube! MMO is very thin but strong in film strength and really gets into all the little crevices and nooks and crannies.
@@tinamcgarrah7794 Ya, STP is like Lucas.
There are 3 additives that I use in all of my vehicles oil and manual transmissions. This combination has kept my 1999 Toyota running sludge free for 280,000 miles and even my Chinese scooter has over 30,000 miles on it. My absolute favorite additive- Engine restorer, I use the recommended amount depending on applications. Small engines get a good soaking in it, I use so much engine restorer in my lawnmower the in side of the block looks Golden. XD That poor thing is older than the car. Second in line is Marvel, I substitute 8% of the oil for every oil change, and toss a few ounces into the fuel tank from time to time. , I also use a bit of Transmission fluid, usually 2% or so. This combo cleans the engines internal surfaces, protects bearings, fills in small scores, and scratches in the cylinders, rings, Valve seats and cam lobes as well as keeping seals and gaskets soft and pliable. Marvel is some wonderful stuff. Its not just for oil and fuel, It works great for Mosquito fogger, penetration lubricant, rubber conditioner and tire shine, Its good for removing tar, bugs and sticker residue from paint, and takes 10 years off of those old grey plastic bumpers too. . Im not sure what else is out there that can be used in so many ways. XP
It is a great product. I have been using MMO for more than 50 years on all kinds of engines for many different problems.
One of my uncles informed me about MMO back in the late 1970s and how he would periodically add some MMO to his gas tank to help the engine run more smoothly and clean out any deposits. I've been using MMO in my gasoline vehicles ever since.
I'm not sure if you want MMO in the fuel of cars with Catalytic converters. I still use it on my lawn equipment though
I've always added it to the fuel. I think it helps the injectors and might add some lubricity to the upper cylinder.
It's used by old time aviators/private pilots, mixing into the fuel for recip engines such as a Continental O-200, etc, for top cylinder lubrication. At overhaul time, shows less signs of wear than an untreated engine.
With modern fuel, you don’t need it in your fuel. All you are doing is pushing oil through your Catalytic converter… I wouldn’t recommend that.
i bet its great for rotary engines.
@@frigglebiscuit7484 As in Brrrrrpppp Dorito Rotary Mazda engine, or an airplane rotary engine?
@@Prosecute-fauci FALSE
Exactly the test of MMO I was looking for. Impressive results and not really what I expected. Nice job with this test!
Long time ago I used to drive a lot on the Pacific coast of Mexico and the gasoline there was terrible, almost constant preignition but we'd dump a bottle of MMO in the gas tank and it 'cured' it right up and as long I didn't run the tank dry it worked for a very long time.
I just bought some of this oil and poured a splash in the tank but now that winter is coming I'm definitely going to add some to the oil. Wow what a performance. The cold flow test is very important for me
MMO is great. I use it in a squirt bottle like WD40. It penetrates rusted bolts etc. really good. I've also had really good results with it on stuck rings and problematic lash adjusters. I add half a quart to all my automotive oil changes.
I have direct injection motors. FB25 N/A, LTG 2.0T
I use marvel in the fuel and in the oil every other oil change and tank. It keeps the oil much much cleaner after I have done it for years. On a scope I have very little carbon on my intake valves
I had a used 1999 Toyota Camry years ago that I would normally fill the tank and keep track of how many miles I got out of it (usually around 300 miles per tank). After i used MMO in the fuel tank and added it in with the engine oil, I got an extra 50 miles out of the tank! This stuff is amazing!
I’m a 52 year old manager of a fleet of vehicles and I can care less of anyone’s test results marvel mystery oil works and it works super good is almost a miracle what it can do in the famous untraceable nock of the 140 2.3 Ford series engines found in the rangers My experience with this product have been positive added both in the oil and the gas highly recommended
I'm glad you told that Joe Biden loving gun banning clown off zombie! I've used it in transmissions also.
I never add anything to my oil, but Redline is the best fuel additive I've ever used
@@toddlesiak3837 I use Mobil one synthetic and motorcraft filters I used redline oil in circuit racing engines in the Caribbean and my experience with it was very positive
@@zombie18d I use Amsoil Signature Series 5W30 & Ford Racing oil filters on my 600 hp 2004 Mustang Cobra, & I seem to have very good results. I've never tried Redline oil yet... just their fuel additive
@@toddlesiak3837 the red line oil was superb after a 30 lap race the main bearings and connecting rod bearing were like new and the oil pressure never came below 75 psi at average of 7400 to 8100 rpm in the little Toyota’s 1.8 3tc engines that oil is awesome, I never used the mystery oil in any racing aplicación I will be afraid of preignition if use on gas ( I used strictly 107 octane) and will not see the need in the oil as we change oil every race but I have great respect for mystery oil in fleet use even to flush engines with sludge it work pretty good 👍
I've added MMO to my 69 Ford truck since 82. It's got well over a million miles on it. In 2012 I opened up the 300 ci. Straight 6 cyl. motor on top and took the oil pan off. I wanted to see if it needed an overhaul. The insides were so clean l was very surprised. It had a yellowish gold shine on all the insides. The oil pan was also very clean, not the slightest sign of sludge. I also add MMO to fuel every time l fill up. The motor still runs silky smooth and has lots of power, enough to pull a 16' trailer loaded with 2,000 + lbs. of scrap metal 40 miles away with no problem. I still have the scale weight receipts.
Since then l now add MMO to my riding mower too.
I've been using it for 40 years was Major success I also use it when I lubricate rifle brass when I run it through my resizing die and it works fabulous
This was cool. I squirt a little in each cylinder before I start a car that’s been sitting for a long time. MMO also works as a penetrating oil. Used this stuff since the 70’s.
i grew up with mmo, i use it in my lawn tractor, can-am atv, all y small engines , add some to my 2016 5.3 v8 silverado in gas and at each oil change and in my wife's 2017 2.4 kia sportage, they both run great, get excellent gas mileage and oil pressure/temp is perfect, i also use sea foam in my gas cans for long term fuel storage, sea foam is better than stabil with ethanol mixed gas
I use it in gas for a upper cylinder lubricant, would never put it in crankcase.
@@bertcochran1770 i mix it with my oil at oil change time, been doing it for many, many years, not one single issue with harm or anything to worry about in my oil,, it cleans inside the engine too, like sludge etc, i love mmo
Me too. MMO has been around for so long. It won't hurt anything. I do the same. I run it with the gas at fill ups. I use in the gas esp when I do an oil change. I do notice a much better response. Cars def quieter. I notice it much quieter in my 200k mile plus Accord. And that was just putting it in the gas. I use it every 2 weeks in all my cars. And weekly during the winter as it gets super cold here.
@@bertcochran1770
Why wouldn't u put it in your oil? It's made to be used that way?
@@sheldonm3535
I go through a tank of fuel a night, how much do u put in your fuel if you're filling up from say a quarter tank?
MMO is a good fuel additive . I use it in my 24v . And my engine drive welder . They both run long hours .
I always thought the claim to fame with MMO was its cleaning ability. It has a reputation for quieting down lifter ticks because it cleans sludge out. In my own, subjective, non scientific experience, it does seem to help quite a bit to clean gunk out of old engines.
Modern auto engines for the most part instruct the user not to use any additives. If the correct oil is used and it's serviced often enough, then additives should not be needed in my opinion.
Clean oil removes dirty oil
New oil has more detergents in it than old oil, so it doesn't gunk up nearly as much. But new oil has almost no anti-wear additives in it at all. But for new engines with roller valvetrains and different metallurgy that is fine because they aren't prone to wear as bad. With old engines it is a huge problem. So like you said, MMO in oil for an old engine go ahead. But in a new engine it's not needed. I'd also not put any new oil in an old engine without adding extra zinc.
Old or new doesn't matter, as long as you use gas with 10% ethanol in it, it will eventually build up carbon inside the chamber and reduce efficiency. It can easily be seen by a probe inserting through the spark plug location. So, often times an additive is good to use. Some pump like Shell that has additive to their oil in it already for the higher priced one.
@@aminulsiddiqui my 1999 Isuzu Rodeo has been sitting for 10 months without moving. What do you think I should do?
Ur right. But some people idle alot more. And we all know even with oil bad gas or when u miss a oil change or two there could be an issue pretty quickly that could be helped with additives. Especially leak fix additives. Most every gasket after 30 yrs will need replaced if it's actually driven
I add MMO every time I refuel and I feel like it makes the engine feel more responsive. Maybe just in my head but it's cheap and isn't going to hurt anything so why not. I have also used it in the oil of neglected cars to help clean the engine out. I see no need to add it to the oil on a regular basis as maintenance though, if the oil is changed regularly and good quality oil is used there won't be any sludge buildup to clean. Of course MMO improved the oil's cold flow since it thins it out, Marvel has said this themselves. The downside to thinning the oil out is that it's high temperature stability and wear protection will be adversely affected. MMO only has a flash point of 128 degrees F, so it isn't going to take a whole lot of heat.
All very good information this is useful thank you.
If it burns off so fast at low temps is it going to last for an 8k oil change cars call for these days?
@@ConquerCollin you use it to clean not protection
@@ConquerCollin Hi Collin, as far as adding it to oil, you're supposed to add it 300 miles before you change your oil, not for 8000 miles.
The flash point is for MMO on its own. When mixed in the oil and run through heat cycles the characteristics change. Personally I use a slightly thicker oil when using MMO to account for the change in viscosity.
Ive been using MMO for years in my 2 stroke boat motor good stuff👍
It's also good for valve guides to stop start up smoking I used it in a Lot of older engines
Based on my years of using Marvel Mystery Oil, I can whole-heartedly say that it can probably cure whatever ails you, your engine, or your transmission.
Transmission? Haven't heard about that yet. You mix it with your ATF?
@@davidquinn9676 You put it in the lines for your hi/low range selector and splitter.
Great product! Been using it in all my vehicles for decades. I'd recommend it for anyone who operates any type of engine.
How many miles would be recommended to run with MMO in oil replacing 20% of oil at the begging of an OCI??? I’d say 3k is fine but maybe up to 4k
The stuff works. And it's all you need. It does it all. And does it better than anything else. 30+ years of putting it in my gas and oil, cars and motorcycles. Noticeable difference in engine performance and improved gas mileage. Follow directions. You don't have to to use as often as they recommend, unless you're trying to clean up a really gunked up engine or have a tank full of bad gas. Try it.
👍✌
How much are you supposed to add to your gas tank? Please...
The MMO has measurements on the side of the bottle that can be used to add the correct amount. I believe it is 4 ounces of MMO to 10 gallons of fuel. So for every 5 gallons of gas in the tank add 2 ounces of MMO.
Also MMO says add the MMO at every fill up. I would say this helps to properly mix the MMO with fuel.
Always follow manufacturer's instructions.
I use it in my suburban 5.3 LS1 and 2 police crown vic's and no issues I have noticed that my oil stays cleaner for longer now
my buddy swears by it for his 72 mustang.
My Chrysler 2.7 L V-6 engine was burning 1 qt of oil for each 500 miles traveled. One month ago I topped up the oil reservoir with 12 oz of MMO. After 300 miles of commuting, I topped up the oil again with 12 oz of synthetic oil. After another 300 miles of commuting, the oil burning is ended. The engine is clean. The rings seal properly. I'm happy with MMO and my world's worst engine.
I have a 2001 2.7 that's been eating oil lately. I don't see any on the ground, and no smoke. Going to give it a go. I already bought a bigger bottle of it (32 oz) I believe.

How did u use the MMO to clean your engine?
Did u use it as a flush by pouring in about a qt. for like 15 mins then change the oil or did u use a qt. and drive around for a few thousand miles?
@@motorcitymanman7711 Bought a car with neglected motor. Ran valvoline 5w-30 and 8oz marvel mystery oil. Ran for 1000 miles and saw little bits of sediment at the bottom of oil pan when changing oil. Not sure if it made the difference, but this time I’m going with a higher detergent oil like rotella t6 and using half a quart. Gauging from last oil change I could run it like this for 2k miles at least before changing oil again. Not everyone has the money to change oil every 500 miles so this might be the happy medium. Also consider running thicker oil especially if you take short trips because not only is Marvel mystery oil very thin but gas will collect in oil if you take short trips like I do. Hope that helps!
@@mikeypotts4732 I used mmo in a neglected 2006 prius. I used 1/2 a quart in a 4 quart oil change, so about 12.5%. On the first oil change with mmo the oil turned black in about 100 miles. Over the course of 8k miles and 7 oil changes with mmo, my prius runs noticeably better. now, the mmo-spiked oil doesn't get dark as fast. The oil-actuated variable valve timing system now functions like it should and it went from 40mpg to 48mpg.
It has also gone from burning 1qt of oil every 1k miles to 1qt every 3k miles. I'm normally not a fan of oil additives, but mmo actually works.
I have been using this stuff for years as an oil additive in my cars. It's a nice affordable well kept secret.
About 15 years ago, had a 1987 ford ranger with a v6, started running rough grandad said pour mmo in the intake till the truck dies and let it sit for about 2 months, so hesitantly I listened, and 2 months later fired it up and it was running just fine, dont know what really went on there but it worked.
I appreciate you sharing your story with the NIA community.
Amazing...
I was surprised.
I put 4 oz in a 2009 Chrysler town and country with the 4.0 v6 to get rid of a cold tick 400 miles between an oil change and it works! The vehicle is whisper quiet at cold idle now
Great story MMO is used for many purposes.
Next test should be 2 oils of the same brand but a 0w20 vs 10w30, heat both oils up to around 200F, then the bearing test while the oil is hot... What would have been a nice bit of info would have been an oil analysis of both oils.
I've used it for years, my grandfather used it at his shop. A friend had an old Chevy pickup with a quarter mil on it, so bad it couldn't get out of its own way. He was going to replace the motor, I told him to put a quart of MMO in his engine and one in a full tank. He showed up with the truck a month later, still ugly as sin. Lifter noise was gone, engine ran smoother, and a fraction of the smoke.
For the noise in the elevators do I have to mix it with the engine oil?
I’ve seen it used as a cleaner. Add one bottle to a oil change, run 15 minutes, then drain. It eats a lot of carbon deposits out of the engine. But I would not leave it in there more than 15 minutes
I had a leak with the main seal... my Dodge ran on 2 quarts of oil! Thank God I put Marvel Mystery oil...
It seems to stop my KIA turbo 2.0l from consuming so much oil during each fuel up, and decreased the ticking noise in my hemi charger. It really works for some reason!
Hey Nate,
Can you try Full Synthetic 0w20 with Lucas Low Viscosity Stabilizer vs Regular Full Synthetic 0w20?
Would love to see how much wear does Lucas prevent.
This is basically a light machine oil with some wintergreen scent. I don't know about the detergent package, but it is well known to stop sticking lifters, and an oil change after 3000 miles of 20% Marvel Mystery Oil shows a lot of dirt in the filter. This product probably removes grime, but it thins the oil so watch your oil pressure if you use it. I've used it for 40 years to preserve RC model airplane engines.
@Baldspot It's mineral oil and mineral spirits.
Is only thins out/drops points on the operating number by like 3 or 4 points so a 5w30 would be a 5w26 but that’s fine it’s not a big difference and you engine will be lubricated
Nate , on your next video could you consider a house brand farm one of the big box " farm" stores . Traveller brand motor oil if possible from tractor supply . We keep it in bulk around here . Never heard of anyone testing it . Not even on " Bob the oil guy "
Good suggestion thanks
I just added this to my oil change yesterday lol
If you have a collapsed hydraulic lifter, run this stuff for a week, drain oil and put in regular oil after it has stopped, works great.
How much should I put in the oil? Whole bottle? Mine takes about 6 quarts of oil.
@@plutosforest just replace a quart of oil with the marvel mystery. So 5 quarts of your desired oil brand and type and a quart of MMO
Been using it for decades! Buy by the gallon, great long term furl stabilizer for generators, off roading vehicles, lawn equipment etc. No more plugged up carb jets from ethanol laced gas.
Any chance you could do this with other weights like 5w 30
I have question for u guys. Will MMO added in the crankcase or fuel cause smoke like seafoam? It burns out carbon right?
Bump question
Just did my first oil change in my 2023 GMC canyon and replaced a quart of oil with MMO and WoW! What a difference it has made. Acceleration is more responsive, truck feels even lighter and 3 more MPG. I love MMO!
I use this in my oil every winter, if I don't my engine ticks, I live in north Idaho and I can tell you it works
I add this right before I'm about to do an oil change and run the engine until it's up to temperature and let it cool back down but I never really hammer the engine down when I have this in the oil I just act like a grandma on a Sunday cruise and then I change the oil. Doing this has really seemed to clean the black soot out of the oil in my Cummins swapped f250 and I add a little to fuel in it from time to time but I've mostly went to hot shots secret for my diesel fuel treatment but I try to add quite a lot to the older gasoline carburetor cars that don't get drove very often, I believe it helps break down the carbon build up on the Pistons a little but I still have troubles with the rings no sealing on the one so I'm going to try soaking them GM top cleaner and see what happens
I remember my dad talked highly of mmo since the 60’s. I have used it a few times.
So would you recommend MMO for winter in Michigan? I always thought this was more of a cleaner than a lubricant.
Thanks for doing a cold pour and wear test of Marvel Mystery Oil Nate. I have been using MMO in the gas of my 2002 Lincoln Town Car and 2002 Chevy truck for 4 years with great results. The idle is smoother, and both vehicles seem to have more power. I have always kept records of the highway mpg in my car, and since using MMO, it has increased at least 1.5 to 2 extra mpg.
I have always bought the quart (32 oz) of MMO at Walmart for $3.88, and at that price, I am actually saving money using it with the savings in using fewer gallons of gas.
I really appreciate you helping the NIA community by sharing your experience.
I recently started putting MMO inside of my 2017 Ford Focus engine 100 miles before each oil change, and the amount of gunk that comes out is incredible! I’ve noticed the engine is stronger, the idling is smoother, and I’m getting better gas mileage after the first oil change! I can’t wait to keep this car going for a while because there is nothing more satisfying than taking a shitty vehicle and making it last 200-300k miles.
@ Andrew Salazar My 2002 Chevy truck with 144k miles uses about 1 quart of oil per month. When it is within 500 miles of needing an oil change and is a quart low, I put in a quart of MMO. It is amazing how much sludge comes out when doing a oil change, especially the first time.
frank new - You're lucky you can get MMO for $3.88USD! Here in The Great White North(Canada} it's around $6.00CDN if you can find it.
@ Roger Tycholiz--- For more than five years, Walmart has sold the quart (32 oz) size of Marvel Mystery Oil for $3.88 in the USA. Yesterday I went to Walmart and bought three quart bottles of MMO and they have raised the price 10 cents. It is now $3.98.
With inflation, I am surprised that the price has only gone up a dime in more than five years. Many auto parts stores sell the quart size of MMO for a much higher price, usually about $6.99. I checked Amazon recently, and their price was extremely high.
Please share your experiences with MMO good or bad.
Try metal lube pleaseeeee
it cleans and lubricates
I have used marvel mystery oil for 50 years in all my vehicles and never had any problems with my engine and now I have a 2011 Chevy Silverado 1500 4.8litre 247,000 miles on it and no problem
Do you add it before the oil change or leave it in after oil change
I run marvel in all my vehicles. 4 cylinder nissan altima runs like new after about a year of running it in gas and engine. Used it as power steering fluid because winter kept freezing the fluid. Ps is like butter. My other hondas enjoy it and seem to have no bad effects. I also got some videos on what I've done. Gotta love the updates you put out showing what this mystery oil does
@Joby Fluorine no, it does not. But it makes it very thick. So thick that hoses blow up, or the pump cant make the flow fast enough to keep up. This also causes stiff steering until it warms up. Try a -50 winter.
An ad for MMO. It has solvents similar to WD40 so it thins the oil you add it to. Of course it will flow easier. The coffee pot only gats to about 140F, engine oil can be 250F plus. The wear test difference is trivial. Good for air tools though.
Great reviews bro!!! Awesome 💪
The mmo has been around since 1923... used in WW2 in fighter planes upper cylinder lubricant and many civilian uses there was a kit
To use as cylinder lubricant for many engines using spacer plate under carburetor and glass jar on firewall .. I have 2 older Cadillac cars
And flathead power vehicles with this kit .... I use MMO in many engines that have been sitting for years by filling cylinders and soaking engines
And I add to fuel and oil to run engines that have been dormant for years .. or as lead substitute on some engines... and I use in my newer
Cars and trucks... it really works ... especially in fuel injection systems.
Hey thanks for.the comment. The more I've looked into this , the more good things I hear people saying about it. However after this video and some others , I've started to become serious about using this. What my main concern is: puting something like this , being so think into my gas tank and clogging the fuel filter....
@@lifepresent3183 i use in my 2017 ram
Just filled up my 56 nomad 6 oz per 10 gallons gas
No clog issues
Now like my diesel trucks use mmo and power service fuel treat winter mix
For 35 and colder I use this mix warmer I use mmo every 3rd or 4th tank
Never filter clog issues
@ quagmiredavis4117-- I agree with everything that you said except that Marvel Mystery Oil came out in 1923, not 1929. In fact, I have a quart bottle of MMO that I bought in 2023 that says "Celebrating 100 Years."
It's good to see that you have a 1956 Chevrolet Nomad. I recently saw a beautiful red and white '56 Nomad at a car show in Daytona Beach, Florida. There were at least ten 1955, 1956, and 1957 Chevrolets at this show.
Some people say to add MMO a few hundred miles before an oil change, but others say to add 1 quart less at an oil change and substitute with 1 quart MMO. So then they would run MMO all the time. Is there any special problem of the MMO breaking down faster than regular engine oil?
These oil additive test are the best. Need to try BG MOA.
Much love thanks 😊 as always.
Yes, test BG MOA 110 and 115

after emptying the fuel tank of my small yard engines and running the engine out of gas, i add a few ounces to the empty tank, crank it a bit 5o fill the carb and engine with mmo.
You're talking about winterizing your small engines with this process I assume?
@@TheLaidbackBiker it really has nothing to do with cold winter, but more to do with the gas evaporating and turning to varnish. it will cause the needle and float on a carb to stick. i have a portable generator i purchased in 1997 at Costco. I used it 10 times over the years for superstorm sandy, 2003 NYC blackout, etc. for a few days or a few weeks. the rest of the time it sits in my outdoor shed with a tank filled with 4 ounces of marvel in the carb bowl, cylinder, and tank. i believe it is more useful in hot weather where the gas evaporates quicker and leaves behind deposits tho. yes, i also use it in my snow blower for winter storage.
I've used MMO long as I can remember. Like someone else here said, Could just be in my head, But it seems to help....
Great test , I run ancient 350 chevrolets I run it in fuel and oil . They do not get daily use and I am glad I'm not wasting money . They sit for weeks and then are forced to run 4000 + rpms and then idle for hours . A little extreme for 30 -50 year old engines . Never had a failure yet
Great, this helps others to know how MMO can or cant perform.
I use MMO in my 2 stroke motors. I just ad a couple cap fulls.
I drive a 2005 honda crv with 318k miles. I did an oil change at 315k, 4qt 5w20 and 1 qt mmo. Normally I add 1qt of oil between oil changes. I have added 2 qts in the last 3k miles. Not sure about the mmo yet? hopefully it will go back to burning 1 qt between oil changes.
I have to note "MMO contains 0-1% chlorinated hydrocarbons" That is a small amount and is some of the stuff that makes it work. Does work in the fuel cleans up the sparkplugs well. And even sucked it in my engine through a vacuum line before, like a gal of it letting the car sit there for a week blowing it out on the highway. That was a 2000 car not a new one! It's use in oil could cleanup the piston rings if used for a time in the oil. You might have to use a thicker oil with MMO to not be watered down too much!
MMO is great for fuel injector cleaning when added to gas👍🏻
How much are you supposed to add?
I replied the answer in the previous comment you asked. Check it out.
Do Rotella t 15-40 v some other diesel oil
I put mmo in my oil about 500miles before a oil change, and some in the gas tank sometimes although ive switched to lucas upper cyclinder in the fuel tank.
Recently I've added MMO to my oil because of my shorter trips back in forth to work (noticed some moisture on oil cap)
Checked cap recently after a few hundred miles and noticeably less moisture in oil cap.
On older vehicles u can take out the spark plug and dunp right ontop of the cylinder to help unstick them old rings
I put a bit in each cylinder when I set an engine up to store
There is a lot more to oil performance than just a viscosity test and a test of film strength.
That was a great test. Could you do a similar test with BG MOA?
Old harleys love it mixed in the gas....i put it in my lawnmowers gas,its been running for over 20 years
An it’s probably kept better than some that are 2 years old
I used it to clean model bout fuel engines.
It's also very good to keep mosquitos away. Just wipe a bit on your exposed skin and the mosquitos will not bother you.
haha
I added it to my windshield wiper fluid and they haven't squeaked since. 😎👌
The Marvel Mystery Oil is probably keeping your windshield wipers clean and lubricated.
😊😊
LOL
