You can not run a car on vegetable oil. The oil needs to be converted to Biodisel first. This link gives the basic details.

But be warned using this WILL invalidate your warrenty and the chemicals needed are toxic/ corrosive.
I would only risk it in an old banger.

I have just read the whole article 'veggiepower' and I have to say DO NOT EVEN THINK ABOUT IT. !!!!
I am a Chemist (39years in the lab) the procedure in the link is VERY dangerous, there is a very strong chance of accidents , chemical burns or fire. Methanol is highly flammable and very toxic by inhalation ,skin absorbtion or injestion, it causes permenent blindness. Lye (Sodium Hydroxide) causes severe chemical burns. Iso Propanol is also toxic and highly flammable.
On a practical level you would be very unlikedly to be able to buy the chemicals, some of them are allso used for bomb making, you risk having the anti terrorist squad on your doorstep.

Not rue about the bomb squad Eddie51. You bhave to register with customs and excise to pay your duty on it and the paperwork should allow you to obtain such chemicals and prove what you are up to. Having said that, there are some nasties involved to get the Glycerin & Water out.
As a producer you may use up to 2500 litres od Biofuel a year duty free, which is about my annual consumption of diesel. I wish I had somewhere to make Biodiesel.

Ok, the issue with using oils is they clog up the injector intakes.
There are some car companies that recognise this and build cars with better injectors (Ford and Saab I know for sure).
The point of using oil is you need to heat it so it is more fluid and not thick and gooey.
The fuel pump needs to be replaced with a stronger one, the injectors need adapting and a very very fine filter is needed to catch debris.
The car also needs to have a small diesel tank to start the engine, heat up the oil tank (where it then switches over to oil) and then when you are about to turn the engine off... or are a mile from home it reverts back to diesel to clear the oil from the engine and pipelines.
In essence, yes older than 04 diesel engines can cope. But don't bother using "used" vegetable oil as it is such a low performance dirty debris filled fluid that it isn't worth the hassle.
Convert it to rapeseed instead.
