Driving on Vegetable Oil

[@ballardstowingandoffroadre2367]

I understand your video 100% !! Everyone is getting stuck on the return lines, But to help everyone understand a little better, You could actually just block off the return lines !! I have 3 diesels with the return lines blocked off !! It hasn't changed or hurt anything in over 10 years !! Stop sweating to small stuff ! This is about as simple a system as can be built !! And it's RELIABLE !!!!!! Many other systems fail only after a few months !! This one will last forever !!

[@gerrys6265]

Great explanation. I have been using Veg oil in my vehicles and boat for about 12 years. I settle it for 6 weeks or so, then gravity feed it through a 10 micron bag filter (they are cheap and last a long time), then do pretty much the same thing as described here. The only thing I would caution is to make sure your vehicle hoses and seals are compatible with Veggie oil. Rubber is eaten in no time by the stuff. If you have rubber seals internal to the injection pump or elsewhere, you will do major damage after 6 months or so....I already did that without knowing ...the manufacturer couldn't tell me so I took a chance!). Most engines after the mid 90s apparently do have veggie compatible seals (Viton is one name for them) . Go for it!

[@Lifeless11111]

i dont see how vegetable oil can eat through rubber more than diesel .. diesel is much more chemically dangerous than vegetable oil

[@artofnoly9754]

That was the cleanest clearest explanation of this subject I have ever seen!!! MEGGG-R!!! Many thanks for that. You have endorsed what I believed was totally possible. Thunderbirds are GO! It is my passion to follow in these great footsteps, with a Toyota Coaster commuter bus, and journey around Australia (my homeland... a very big space it is, lots of kilometers between towns, especially in the wild West... but, with plenty of deep friers too... we love our junk food as much as the next supposedly first world civilized nation). I want to be able to drive anywhere I like here in the land down under, becoming a seasonal grey nomad... doing the hot north in the winter and the cooler south in summer... including Tasmania... and all for free... (well almost for free), expending only the effort of gathering and filtering the used cotton seed oil*. * Very good type of oil for use in Diesel engines, by the way for those who did not know that. Very low in trans fats, which makes it thinner. That's why it is so good for deep frying fish and chips. Easier on the human heart in a longer term sense as well. Again I say, many thanks for sharing. Love your work!!

[@artofnoly9754]

Great info about the micron size of the fuel filters. Something I hadn't really considered before. I heard that 50 microns (which my filter bag is rated at) would be enough to produce oil thin enough to go through the injector pump of a standard Diesel engine. But I see your reasoning to be cost efficient and also reduce the risk of hassles/breakdowns... especially when you are in remote places... which is where I fully intend to be, as much as possible!!! Yeee-Haw!!! See ya on the road, Kids!!

You are a very well mannered hippie. I subscribed.

[@mitchflanigan1546]

you are doing good things. thanks for the video

[@off-gridhomesteading7269]

I appreciate that!

[@alsdjfknbo]

Really good video! Thanks. No one has ever gone into the depth that you have. You answered a lot of little questions that I had. Thanks again

The major issue with the return line being routed back to the pump feed line is that if any air is introduced into the system it will cause the pump to cavitate and render it useless for moving fuel through the lines. Routing the return line back to the tank will not only help eliminate air from the system but aid in heating the tank oil and help circulate the tank.

[@off-gridhomesteading7269]

Never had a problem with the way the return line is and it is now about 15 years that I have been driving it.

[@theaussienurseflipper.8113]

Here in Australia, they lock the old oil up. Most places will not give it to U

[@Hobby_Electric]

Present this car to german Tüv please :D

I recently sold my used cooking oil recycling company, but my videos from the last few years may benefit your viewers. Be advised the channel contains common vulgar language from time to time.

[@khaleelseivwright2224]

Hey, thank you for this video, it has been the clearest to me trying to understand wvo for myself. I was curious about your diagram and why the diesel switch valve comes after the fuel pump and not not before. Is there any problems with the diesel getting to the end when you start and flush?

[@off-gridhomesteading7269]

The extra fuel pump is only needed for veg oil and not for diesel. Therefor it is on the tank side of the switching valve. It is off when running diesel and I only turn on that extra pump when running veg oil.

[@jozsefienciu2325]

In Hungary you can not make it because the excise tax

[@koushiksinha8447]

Wow.. U r great

[@ehimapa-s8171]

Hi good afternoon, I have a school bus and I want to convert it to utilize waste vegetable oil and I was wondering if you be able to help me out

[@off-gridhomesteading7269]

No, sorry

[@stefankaiter-snyder6821]

With the return line connecting before the switching valve, would the diesel circuit return to the veg oil tank? It would need to be after the switching valve yeah? Building this system myself and running into this as a design issue. Would love input.

[@off-gridhomesteading7269]

Mine is still working great. No issues the way it is.

[@shanesmaineshop]

your diagram is not showing where the diesel fuel return goes there is something missing from your diagram because if you send diesel back the way you have the diagram it has no place to go. Am I missing something?

[@off-gridhomesteading7269]

You did miss it. The return line goes back into the feed line on the tank side of the switching valve.

[@shanesmaineshop]

I mean no disrespect I am just not seeing how it works in your set up. There is still no way for the diesel to get back to the tank when in diesel mode. At least according to your diagram at Min. 21:34

[@asc556]

@@off-gridhomesteading7269 The return line goes back into the feed line and that work fine with veg oil. But what happend when is on diesel? the return goes back to the veg oil tank?

[@off-gridhomesteading7269]

Sorry if the diagram is not perfect. The person who made the video for me/us did it for free to get the info out there. The return line does not go back to either tank. Like the video clearly states, the warmed fuel goes back to the feed line and is sucked back into the engine.

[@off-gridhomesteading7269]

Both the diesel and the veg oil go back into the fuel feed line and then to the engine. Never back to either tank.

[@stitches4897]

Is this a 12v Cummins or a 24v Cummins with a vp44? Curious because my truck is a vp44 truck and I would like to know if this can be done with my type of injection pump

[@off-gridhomesteading7269]

12, I do not suggest that you try this with a 24 valve. The 12 valve works fine, but the 24 valve motor might get damaged.

[@freedomdove]

I'm confused about the return line for the veggie oil. If the purpose of the line is to rid the engine of excess oil (presumably when you flush the engine before turning it off, right?), and your return line is making the oil go to the system (the engine), then how is the engine going to flush the oil? Is it just such a small amount that it doesn't matter?

[@off-gridhomesteading7269]

I am not a professional diesel mechanic but I understand that the fuel pump usually pumps more fuel than needed. So the return line just sends the extra fuel back.

[@johnbrakingground]

What I did and is recommended is to run 2 pollack valves so when you switch one valve from diesel to veggie you just wait another 20 seconds or so and switch the pollack valve on the return line so that the veggie oil is returned to the veggie tank and the diesel returns to the diesel with very little of either being put into the opposite tank.

[@off-gridhomesteading7269]

The return line does not go back to either tank. Like the video states, the warmed fuel goes back to the feed line and is sucked back into the engine.

[@alixsnyder3423]

how much total would you say it cost for the entire system?

[@off-gridhomesteading7269]

About one thousand back in 2007.

[@off-gridhomesteading7269]

Back in 2008 it cost me about $1,000.00 doing most of the work myself.
