Diesel Truck Conversion to Vegetable Oil

Has anyone looked into converting their diesel engine to vegetable oil? I know there are a number of converson kits out there. The source of vegetable oil would be local restaurants, who, as I understand it, must pay to have the used oil removed. If that's the case, they would welcome having someone take it off their hands for free. Any info would be appreciated!

I researched this about 2 years ago and think it has merit if you're willing to invest the time and money to get it started and keep it going. I think that the main obstacle is finding a consistent source of good (relatively uncontaminated) vegetable oil from a local restaurant or two and then building the necessary equipment to filter water and contaminants and then preheat the oil before injection.

You also need to carefully evaluate your source(s) of oil. In most cases (at least that's what I've been led to believe), restaurants actually contract to have the used oil periodically removed. While they may be happy to have to have someone remove it for no charge, the oil may actually be owned by a salvage firm and you may be liable for stealing their property. Needs thorough research.....

Still, the idea of almost free fuel is appealing and let us know how you make out.

I have a 100k/5 year warranty on my Duramax...I would not even consider burning anything except what GM says is okay.

I can't imagine giving up 5 yr warranty to run a "French Fry Diesel". On other web sites there have been problems with running vegetable oil in that it clogs up the fuel filters at first.

Rudi,

My brother has six restaurants in Florida. He runs almost all of his trucks on his vegetable oil that he recycles. If you PM me your phone number I will have him call you.

Even in Florida he has to run some diesel in with the oil because of the thickness of the oil. He filters all of the oil himself at one of his restaurants.

He is very happy with his system, and I think he told me that it costs him 80 cents a gallon. That might not be correct so don't jump up and down about the low figure as it might be higher. Just remember he already paid for the oil since it was used in one of the restaurants.

www.greasecar.com these folk's make the conversion kits for trucks and cars. The older diesel cars are easier to convert to veggie oil that the newer vehicles. However the newer vehicles handle BIO-DIESEL very well. That is veggie oil that is converted to diesel. it just takes two additives. From the Cummins folk's they have OKed the Cummins diesel for B20 meaning 20% bio diesel with 80% regular diesel. MUDCHIEF has relation running 100% bio and have been for years. I know of two folk's that are running 100% bio in there trucks and have been for three years. WHEN YOU GET THEM TALKING THEY JUST SMILE....ACTUALLY if you check several of the bio diesel site's you will find that the lub qualities of the bio is much much better for your engine then regular diesel. If you get on e bay there are several bio diesel systems up for sale. The one guy in Missouri always has some, I contacted him and he said I was welcome to come down and he would give me all the instructions and make enough for my tank to drive back on.. It's getting the that point, I might take him up on that. Actually someone should start doing instruction and demo's of bio-diesel at the rallys...............safe travels John

Is it reasonable to think that if there becomes a "demand" for used resturant oil..it will be free???

My brother in law has a friend that makes all of his own bio-diesel from used fryer oil. He runs a 2005 Dodge and a VW rabbit diesel. Brother in law made a batch and mixed it with regular diesel. He is trying to find enough fryer oil to support this habit but many others have the same idea. All the places that I asked have it promised.

The businesses around here that contract for removing the oil from restaurants, are complaining that it is stolen from their containers before they can collect it. A very high demand, in all respects.

I ran across this site while doing some research some time ago. Don't know anything about it, other than what you can read. Some sort of additive for running veggie oil.

A local college(Oberlin) did that experiment some time ago and ran the unit cross country.It was very expensive at the time but I am sure the technology has improved.

I'd try it but with the warranty as it is now and I only have about 22,000 miles into it! Another reason I won't use the veggie oil is I don't want to have all the dogs in the neighborhood chasing me down the road wanting to bite my exhaust pipe! The idea of wanting to have a hamburger everytime I start up my Duramax is a little un-nerving also!!

Same here.

A diesel engine, although a beast when working, is sensitive when it comes to fuel. The diesel fuel needs to be clean, fresh, no water in it, no crud in it, etc. I'll let somebody else test this stuff out...if it works, fine, but I'll not be putting in my engine.

Thank you all again for your input. I think the best thing to do is to talk with people who are using veggie oil in their tanks and see how it is working out for them.
