Waste Vegetable Oil (WVO) Diesel Conversion - How to and how it works!
HTML-код
- Опубликовано: 13 сен 2024
- This week’s video is all about waste vegetable oil (WVO) or, more accurately, how to install a duel fuel system that will allow a diesel engine to burn french-fry grease! About 7 years ago I installed an alternative fuel system in my 5.9 cummins and since that time I’ve saved thousands of dollars not having to buy diesel. I’ve run this truck in sub zero temps with no problems at all.
We’re going to walk through the fuel system and describe how it works. There’s no need to produce biodiesel. With this system you simply burn straight veg oil. The system has a lot of plumbing and can get a little confusing but it’s simple in the way it works.
We use the hot coolant to heat and thin the veg oil before it goes into the diesel injector pump. This is where all the plumbing comes in. I’ll show how to build a counter current heat exchange hose and an aluminum coil to heat the WVO filter.
As you can probably tell I've got a serious aversion to debt! Burning waste vegetable oil I can get for free is just one way we save money. We're also doing a major remodel of our farm house using salvaged lumber and rough cut timber we milled on our little homestead. Subscribe to follow along!

This build is absolutely incredible. The fact that you could get the parts for $500 and instead of using electric solenoids etc you just did it with regular valves is so simple and sensible. Bulletproof and saving a dime. If only more people thought this way. Do with less. Best of luck from your neighbor in Montana!
Thanks much
Mechnical Engineer here, very impressed. The counter flow heat exchanger and heat exchanger on the filter is a smart.
Up until now I've just watched your archery videos, I'd love to see more of how you live self sufficient 👏💖
Watched this video about 40 times over a month. Takes a while to get my head around this stuff. I made a similar heat exchanger instead and went with a 1-inch steel pipe instead of a rubber hose and 1/2-inch copper through it and used that as a Heat Exchange just near the Injection Pump. I didn't get as far as doing a "mobility moment" but i think might have spent a record amount of time in the hardware store peacing together fittings. And back again about 30 times. Thank you for explaining the system well.
I know I’m a bit late but I would like to endorse this video. There ARE slightly easier ways to do this but everything this guy says is basically valid and correct. I’ve Been doing this for 12 years at around 40-50,000 a year with ZERO problems. Diesel in Australia averages at around $1.50 a litre. You do the math(s).
1.If you store clean veg oil, try to store it in plastic.
2. Don’t use it just for short runs around town.
Please resume the easier ways you name to do this...thanks
@@danylman7 I use electric changeover valves on my trucks. I loop the fuel returns for both diesel and oil back to the inlet side of the filters(this keeps the oil filter warm with the returning oil and saves the diesel tank from being contaminated with oil at the changeover lag). I clean a thousand litres at a time and the 2-3 months it takes to burn that oil gives the oil I have collected time to settle out and saves my plant filters from being blocked too quickly, it also settles out most of the water. I actually have two stages of settling which takes 4-6 months for the oil, once collected, to get to the point of being filtered. I only have to change my vehicle filters at time of oil changes as a precaution, they never block as my fuel is clean. Warning! Cutting corners on oil cleaning will end in tears. Be diligent.
@@todaywefly4370 thanks, so you made 40-50k km a year X 12 years on biodiesel?.... You have any video footage of the process you describe for loop filters, etc?
@@danylman7 Sorry no video. I probably should because I think most of the videos on utube are bogus or are new plants that the posters are excited about making and post too early because almost all of them would result in a damaged engine and the rest would be so much work or so expensive they would stop doing it. Looping the returning fuels back to the inlet side of their respective filters is a simple enough process if you are mechanically minded. If you’re not, or you aren’t patient then stop now. There are huge pitfalls if you don’t know what you’re doing and diesel injection systems are expensive to repair if you can’t do it yourself. Also this is not suitable for electronic common rail diesels. Good luck. And no I won’t be doing a video, I’m a mechanic but I am old and have no patience for that.
@@todaywefly4370 What do you recommend for electric valves?
Absolutely admire your skill set , cool that your family is on board.
Thanks
That's a great idea. The problem is, here in Europe that would get you fined: food products are taxed way lower since they are first necessity stuff, if you use them as car fuel you are "evading" taxes, and you may have to pay quite a bit of money for that.
That sucks! One reason to get out of Europe...
That's why we became America 🇺🇸
You are using use fryer oil
So the restaurant all ready pay taxes on it.,
@@eagletrek3 Apparently in multiple European countries you still have to pay taxes on it even for used waste oil, gotta keep a logbook on how much you have used in your car.
Or just get a vehicle registered as farm equipment and never need to eu controll it, and yer in business
This might be one of my favorite videos! I’ve got a 1987 Ford diesel that I’ve been wanting to do this to that was my Grandads
Nice!
I thought I was already inspired by your bow-building and general outdoorsman content and then I heard about this on a podcast you were guesting on and now I have a new vehicle dream all the way over here in South Africa. Not sure if I'll find a Dodge Cummins (or more importantly any parts) but I might try something similar on an old Toyota Hilux or something we get more of down here... Thanks again Clay. You're an inspiration!
Ok, this is crazy. I’ve been watching your stuff about trad hunting for a while now, trying to teach myself about bow hunting off the land. While working on getting started with that during a weird prepper rabbit hole I started researching an apocolypse bug out vehicle, I’ve had dreams of setting up a 80’s suburban with a 12 valve to run on vegetable oil. And BAM you popped up. Thanks for the content brother!
There's no telling what you'll find here! Those 12 valves are bulletproof!
Your thinking may save people in this diesel shortage days ahead. Thank you so much.
Thanks for making the video! I'm actually considering buying an old Dodge with a 12 valve and started looking into the veggie oil conversion to see if it was doable, but I didnt plan on finding a tutorial using the exact same truck and engine that I'm looking at! Thanks for the help! I've got an old Dodge to go buy
They’re great engines!
That part exactly
This will work on a 24v too!
I had.a 5.9 4x4 dually .. I thought I loved that 5.9 more than any motor in the world but now I have a 6-7 that's all built . Supposedly a thousand horsepower and I believe it. . Purs like a kitten rors like a lion.. the thing is phenomenal . The other day I was pulling out this giant tree for my neighbors that had fallen on their I barely gave it any gas at all pull that monster tree out like nothing I'm talking I didn't even have to bring up the RPMs .I love Cummins
I just take 4 gallons of very well filtered waste veg oil and 1 gallon of gas, I actually mix it prior to my final filtration, and then I just pour it straight into my car fuel tank, no special filters, hoses or tanks, I have saved over $50,000 in the last 15 years
Seriously ? Teach me how haha … plz
Early 90s I work in junk yard in Nebraska, the Cummins had just come out we built a 4 door Reilly out of a wrecked one and and 1986, dodge didn't make a crew cab till it changed body styles. When people seen that one we made and sold 100s of them around the country as fast as we could get totaled cumimins.
Quite a journey you're on there Man. Thanks for sharing.
Thanks ya
I've done copper tubing by putting water in it and freezing it. . It worked freaking awesome it was actually better than the sand for me
Thanks so much for sharing!
Being three years ago, lets see the kitchen!

By all that is Holy, THIS IS GREAT! How could I not know about this delightfully affordable answer to the much touted ( to me, anyway ) electric option?!?
Our "bad crowd" acquired a 2006 flex fuel Silverado and, ironically enough, we moved to to Oregon later and found that there is no Ethanol AT ALL for retail sale in the state. We actually lost brownie points by not flexing our fuel properly!
Thanks for the excellent tutorial, I'll make sure to share this video with the guy who makes this magic happen to the sweet little red 1980-ish German Coupe I have both my eyes on. Cheers, Dudes! I'm so happy that I might let my husband watch the mechanic work on my new baby!
😆have fun!
You guys seem fun to hang out with! Thanks for making this!!
You can look into AN fittings like a bulkhead for in a tank etc. Drill hole insert the bulkhead fitting and attach desired AN fitting as needed on each side. In the tank heater one can just use a flare nut and flare the line then bolts right up. On outside there's any number of fittings available to adapt to pipe threads, 90's or hose barbs etc I believe 1/2" would be AN 10
18:11 you can prime it with compressed air in the tank too. I've done it on a Peterbilt 357 a few times. (It was with off road diesel tho)
THAT part exactly it works better
Yep. I had the fuel system apart on my new Holland 885 and the hand primer doesn't work. Took off the return line to the tank and pressurized the fuel tank with compressed air until fuel came out the return. did this by simply wrapping a rag around my air nozzle stuffed into the fuel filler on the tank.
Thanks for your good reply . I thought so but it's nice of you to take the time to reply. All the best.
Run my 7.3 off used transmission fluid now going to start doing a 50/50 mix but I’ve already got two tanks and I have ran the truck off strait transmission fluid for a couple weeks In the summer did just fine just another way to supplement fuel! But I plan to filter and mix so I can just put it in the one tank I use for “alternative” fuel
Hey! Nice one! Is the veg oil filter something special or just another one like the ordinary diesel filter? Whats the reason for having two different filters? :)
Love the truck!! What kind of vegetable oil are you running? I have a 2001 VW Jetta TDI that I ran straight canola oil in last summer but it leaked fuel when running it I’m guessing from the injection pump and was hard starting on straight canola but 30% diesel 70% canola seemed great. But never tried it in the winter, how does the cold weather effect your truck
Hey i would love to talk to you, I've got a VW tdi also ALH. I want to do that as well on
Thanks for all the tips friend.
Nice video and super nice pickup!
Thanks
Can you draw a simple diagram of how you have your coolant/ fuel hoses setup?
Dude that was awesome! It was good to see Benji a little bit!
Thanks
Great information. I may need to visit you before I convert my f350 6.7L.
could you also show or explain how you made the in tank fuel heater? thank you.
your a man of many talents very impressive
Thanks for sharing the details with us .
You’re welcome 😉
I just add filtered veg. (soybean) oil to the regular fuel tank in my 1990 12v Cummins. No problems.
Good job bro truck looks amazing
Thank ya
I'm curious on how this would work in canadian winters. The veg oil would be really thick and the diesel aswell.
Dude, you're awesome
THAT part exactly amen thankful goodness
Thanks for the video. Awesome truck and project! I think I understand everything except for the injector cooling and return.
How do you keep from contaminating the diesel tank with the change-over from veg to diesel? Especially since the injector return feeds back to the diesel tank. Would there not be some latent veggie oil in the system that would get pumped back to the diesel tank?
Also, with the veggie oil being heated, are the injectors able to stay cool enough? Seems like they would run hot since the veggie oil is heated.
Last question: what degree thermostat do you use?
Thanks again for the great video. I really hope to do this to my 93 W250 1st gen!
A little veg in the diesel is fine. Pretty sure you can run 3:1 diesel:veg just fine on a stock build anyway
I am curious if you can do a video on all the parts that you used to convert to biodiesel
I would add a pivot handle to connect all three cab valve control arms together since all three need to be in the same down or up position. This way no single valve is not is the wrong position.
Good video man, lots of detail, awesome.
5 bucks a gallon today. Guess in im gonna veg out too.
My friend came up with heating the oil to about 230F before the centrifuge, and adding a light vacuum to the centrifuge chamber. Takes a lot of the water out that just sitting static dosen't get out.
Passes the hot frying pan test for water with only one pass through it.
The only thing I'd change is the return fuel would go all the way to the tank.
.
Ever estimated the temp of your fuel tank after an hour drive or so??
Or any known min oil temp for warm up time.
I'm gessing its all related to amendment temp..
Someone I know just bought one and I may have more future vids on
Rudolph diesel is probably smiling from heaven! Lol. This is the way diesels should be fueled. Not with petroleum. His intention was for the end user to grow vegetables, make oil out of them, and use that oil as fuel. Unfortunately common rail, and high pressure systems has made this almost impossible with newer diesels, nevermind the def crap
I need to do this to my 96 7.3 powerstroke
Im thinking the same thing, my 97 F350 7.3 already has two tanks, its just figuring out the heating of the WVO thats gonna make me have to use my brain a bit lol
Wow you are a straight up prepper, your archery videos brought me to your channel originally
You should start a new channe lol prepping with clay hayes
Love your figuring stuff out!
Thanks for the video !
Would you recommend mixing non kerosene based white spirits with the vegetable oil? 97:3. Apparently is good for viscosity issues.
Brother thank you so much for posting this and sharing your knowledge it had inspired me!!! and also I'm not much of a Dodge guy but I love those old school cummins 12 valves and you sir have one gorgeously reliable Dodge truck. Phenomenal.
Thanks, it’s a great one!
I'm interested in the failure mode of the burst fuel line, what did you do to keep it from happening again?
So damn cool! Plus it’s a crew cab stick shift?
Dam good job bro. Can I bring my 99 Silverado down for conversion? I like your system. I’ll pay you good. Thanks
Nice cup! Oh nice truck too!
I thought you’d notice that!
Awesome video and truck. Thanks for the info.
You’re welcome
Does the vegge oil heater beside the batteries cause any problems? any chance of it heating up? Boxer dogs are the best.
I'd like to add that the best veg oil to use is soybean oil, because it has the lowest viscosity at room temp, which makes it easier on your engine.
Pretty sure all this isn’t needed. Thin out the veg oil with kerosene or diesel and just put it in your tank.
Soy is also terrible for you so it’s better off doing some good in the truck !
@@drsnooker1776 Soy always get a bad rap, I don't know why, it seems people associate it with paper thin vegans. It's a cheap source of protien, has healthy fats, fiber and nutrients.
@@bigballz4u It also mimics oestrogen in the blood. Eat a steak.
@@drsnooker1776 Cows emit a lot of methane, and use our fresh water, food and land that we could be using. Go vegan.
Few questions. I'm lookin into getting another first gen, had one when i was in college but was too broke to maintain it. Damn thing was a ranch truck with prolly 450k on it and everything besides the engine was just wore out
First question, how are you getting your veg oil? Are you just cruisin to restaurants and they give it to you, are you payin?
Second, is it going straight into your tank or do you fill up a separate tank, take it home and filter it? I've heard of a guy who has his own crank operated pump that has a series of filters in it, if I remember right he was able to suck it all into his tank and it would be clean by the time it got there and ready to go.
FIrst gens aint as cheap as they used to be, but I live close to Los Angeles and with the amount of restaurants around I figure I could get away with murder and fill up on the cheap regularly. This is a rad conversion, I like how aesthetically it looks way old school with all the plumbing fittings, super cool man!
Awesome truck! Love the crew cab, I have an 02 dodge cummins extended cab, but with 3 kids, the back seat gets a bit tight. On your roof addition, why did you choose to go cedar shakes?
I like the look of cedar shakes. We’re using them for siding. The roof is tin.
@@clayhayeshunter I never thought about cedar shakes for siding, that would look cool!
5 years later, how is this running mate? Any injector issues?
Awesome thanks
So basically the whole key to the operation is thinning the vegetable oil correct? Kind of like when I sprayed polyurethane foam we had heated tanks and heated line to thin the components to push them out the gun
Very cool! I'm curious why the veg oil return line doesn't go back to the tank though? I assume that's to prevent diesel from getting into the veg oil tank?
The veg oil in the return line is already hot so it helps conserve heat of it loops.
Genius.
Awesome video, great idea.
Judging from the ash tree behind you, what’s the coldest weather you’ve been in to start and run it? Thank you so much for the info. Greatly appreciated.
Low single digits F
I was on one of the first few run-in trips a few days ago Australia on 100% veg running really good, newly rebuilt engine and new VE Injector Pump 1HZ, I wondered why it broke down on side of the road. Just ran 130 kays on a full veg tank ( this is my first long drive) all very good and a full tank of veg with 20 ltr topping it up after the drive, the next day after 10 kays broke down on the highway would only then run if switched to diesel. After sitting roadside eventually deciding that it might be a blocked veg filter I got under and changed it to brand new but the old seemed still good the veg flowed out through it. Then tried to suck the veg up to fill the new filter, none nothing zero zilch, I tapped the tank and it sounded hollow, what, when how where? It is EMPTY?? the veg tank was empty. Can I conclude that when the dogs jumped up onto the driver's side of the bus the return line ONLY got moved over and all the veg went into the diesel tank while it was running go for 10 kays more and filled chock a block and must have went out onto the road through the tiny air breather hole in the diesel tank top, I could see the overflow diesel down the side bus? I opened the diesel cap and it was so full and pressurized diesel pushed out though it is a mix of diesel/veg. I intend to join the two manual three-way valves to one steel joiner so it can't happen again.
That frickin cool man well done
In very cold weather the veg tank have to warm up by first running a while on diesel fuel warming up the veg by heat water hoses running through the veg tank than switch to veg oil
Yes
Could you run a little bit of anti gel in the veg oil or is that a bad idea
Never tried it
That's awesome, beautiful truck! What are the usual winter temperatures you've used that in? Here in Fairbanks, unless we're having an odd winter, 15 below is a warm spell.
I’ve used in in -10 before. I bet it would still work fine way up north. You’d just need to insulate the hoses better.
I know it’s been a while but maybe using a system similar to def fluid would work. Using all electric heaters on a lift pump. A line heater. And a tank heater for extreme cold temperatures.
Very cool thanks for the info. Wondering if you’d be interested in converting my RV for me? Also do you recommend having a bio converter on the truck so you could pour Unfiltered oil directly in a holding tank and making your own bio desiel?
I might suggest you have a small shed or something to do the conversion for bio fuel separate from the truck. As far as filtering vegetable oil…I mean I suppose you could do that on board, but I would suggest the same, filter the oil down to 5 micron with plastic (or metal) 55gallon drums, de-watering filter, then put it in the aux tank on the truck. BAM!
How's the mpg on the biodiesel ?
When you talk waste vegetal oil. You means used cooking oil without transforming in Biodiesel?
If you have 2 tanks already I figure this would be a lot easier.
Ingenuity there. I wish it had been made law to convert all gas vehicles to natural gas long ago instead of flaring it. We ran a 82 valient 500,000 miles on natural gas. It had switch to run poorly on gasoline as range wasn't great.
Sweet video man
I've never seen this much heat applied to the veg oil going into the injectors but it has to help it.
It’s mainly for winter driving. I’m in Idaho and it can get pretty cold.
So you live in northern Idaho as well? I live near Moscow, on the Washington side. I want to get a Cummins so I can do this too
Have you ever had filter clogged ? I filtered my used vegy oil with 2 micron mix it up 20% gasoline because im from canada and its cold here and doesnt work my fuel filter get clog pretty fast the truck lose power and stall
What’s the tow capacity on something like this? Super cool project though. Dipping my feet into the diesel world with a tdi engine swap on my 4runner
Do you have plans?
This is bad ass. Does the veg oil heating system make it take longer to warm up your heater core?
Not that I’ve noticed.
P S love your truck.
great video
What is the fuel economy like on the veg side of that whole system
Mythbusters only showed -10% Fuel economy loss. Probably a little bit more irl situations.
What about performance do you notice a difference
I can’t tell any difference.
@@clayhayeshunter Maybe the only difference is that vegetable oil it's free.
What do you think about doing this with a 24v VP44?
Did you do a video on your WVO filtering system?
I haven't done that but there are plenty of examples online.
Any conversion kit for a 2012 Ram 3500 6.7 Cummins?
Maybe, you’d just have to look around.
How much does that heat exchanger cool the coolant before filter? Ima trying to do WMO system for my 93 IDI. Dsls getting expensive again. Get an electric fuel pump, that stock pump can’t rly do the oil stuff.
Nice, what do you use more and how did you learn this?
I use veg about 90% of the time.
Where do you live? I don't have a lot of tools or knowledge and would like to have help with a project like this on m 1988 F250.
Yo! Whats the filter setup?. Just a normal fuel oil filter?
Fuel Filter for a transfer pump.
How do you prepare the veg oil? Or do you pour it straight into the tank?
Let it sit for a couple weeks…..Filter down with filters ending with a 5 micron filter as the last one, de-watering filter after that, then it’s about ready.
Awsome, and a random question what foot wear do you prefer for hunting winter/summer besides your bare feet mate lol.
I’ve had good luck with Asolo hiking boots. Right now I’ve got the cabellas Alaskan guide boots and like them as well.
cool truck
Does your diesel truck new California emission
Could I run this engine on melted deer tallow ?
I don’t see why not.
