Anybody out there tried running a diesel engine on straight vegetable oil and what kind of results have you had. I am thinking of trying to run my Fordson Major diesel on it.

Hi Huw,

You will need to watch running SVO at a greater than 25%SVO to #2d mix as it will foul the injectors and cause the top rings top stick according to two University studies, after about 500hrs. Do a google search for rapeseed oil.

Biodiesel is not SVO. BD has the glycerine (wax) removed and has approx the same viscosity as #2d. BD takes some VERY nastie chemicals to sepereate glycerine from SVO.

Check out the link below for a good read on BD and SVO.

I ran my "96 Dodge with Cummins Diesel on pure used cooking oil last summer. I wouldn"t try it if temperature is below 50 degrees F. Kept a spare filter on hand just in case....didn"t need it. I think the Fordson Major would probably handle it OK, I assume it has the Simms inline pump. One website I saw listed suitability of different injector pumps. Most of the inline type pumps were OK, but a lot of the "distributor" types were not. I had no trouble starting (it occasionally took just a hair more cranking to start..three or four revolutions of the crankshaft instead of the usual one) and no noticable loss of power. There was definitely less objectionable odor, unless you count the "County Fair" smell as undesirable.

I read an article the other night about a guy who took oil from local restaraunts, added lye and rubbing alchohal to it mixed it all up, let it seperate and then syphon off the oil from the top. This leaves a glycerin base, but he said that he used this in a kerosoen heater and the only smell he got was a little fishy smell, but it burned clean. He also told of a guy who grew peanuts and did the same thing with peanut oil, then fed the ground peanuts to his cattle.

There was a show on public TV the other night about a guy who ran his car on vegtable oil. Used diesel to start it till it got warm. Ran vegtable oil lines through the radiator first to warm it up. It ran fine. He switched back to diesel so it would be ready to start the next time. He got his oil from local eateries. He just pumped it through several oil filters before pouring it in the tank. A guy in Sucessfull Farming magazine sells kits for the conversion.

I believe it will run fine but you have to use a heater in the fuel tank. They claim the old John Deere D will run on crude oil straight off the pump head. I'd sure like to try it someday.

read a book about Rudolf Diesel once, he would try out different fuels and found his engine could be run on just about anything if he tweaked it enuf.

joke was he could run it on dirty water

Tried it.
Gained a little weight around the middle but otherwise worked good.
Then mechanic said arteries were plugged and hardened.

Oh, this was about engines right?

You must have seen the evening news about Willie Nelson running his tour bus on veg/diesel mixture
