looking for cheap alternative diesel i was told vegetable oil could be used my?

I agree with the other guy who said you need more information before you convert. Go to this web site for information on conversion kits:

They also have much general information and links. You should also look on the net for more data on how and why and when to convert.

In simple terms, vegetable oil burns at a higher temperature than diesel. If I recall, diesel flashes at about 280 degrees and vege oil at about 500-600 degrees. The lower number can be reached by the compression of air in the engine, but the higher number cannot. This is why you have to start (and shut down your engine) in diesel and then, at highway operating temperatures, inject pre-heated vege oil into the engine to run on it. Even this is not perfect because some parts of the combustion chamber never get to a high enough temperature, so the vege oil carbonizes on these colder areas. Another problem is that new, electronically controlled engines try to change the timing of the engine to compensate for what it sees as poor quality fuel and further complicates the problem. Most conversions use older engines with mechanical control.

You should look into converting the oil you can get into biodiesel fuel which can be used without much of a problem. You still have to deal with biodiesel being a better solvent than regular diesel (which means you have to change seals and fuel lines) and biodiesel can go 'bad' the same way oil in you kitchen can go bad. This is why commercial biodiesel is a mix of roughly 80% regular diesel and only 20% bio.

Asking the question shows you are a long way from having enough knowledge to try this.

This is not a put down! You have to do a lot of research and know a lot about diesel engines and how they work and are fed.

For what it is worth I recently read that the guy, Herr Diesel(Herr is mister in German) who invented the diesel engine named after him intended it to be fueled with vegetable oil.

There are people who have tuned a diesel engine bus to run on waste french frying oil from McDonalds and run it cross country with the only problem that the exhaust smelled of french fries. The oil was free from grateful fast food managers.

there is a conversion kit that will allow you to run the car on vegetable oil. if you use a lot of vege oil and the state government finds out, they will require you to pay road tax on the amount of oil that you would've used
