Hi i was wondering if a petrol car would run on veggie oil, not grease stuff, clear oil,lets say new veggie oil u buy in store, would it run mixed with petrol,,i,m sure there is certain amount you could add, i mean if i had 20 litres of petrol and added cup full of veggie oil i,m sure it would not matter, mean i,v had petrol car that burnt a lot of engine oil, isn,t that same, so what amount do you think you could get away with adding, 5 gallons petrol, 1 gallon oil ? would it run?

I know some people in Germany who tested VO as 2-stroke oil in gasoline for chain saws. They concluded that it works fine, and the results indicated that they could reduce the oil concentration to 1% instead of 2%. Nevertheless, they would not say that the tests were completed, and would thereby only recommend people to try it as an experiment (no guaranty).
I don't know how >2% oil the gasoline will work in a 4-stroke gasoline engine, but with a 2-strokes it gives a terrible smoke which, hardly is good for the engine - and definitely bad for the environment.
I'm running my 50 years old Massey Ferguson 31 tractor with some % VO in the gasoline, to lubricate the valves because I use un-lead gasoline.

Even if you plan on replacing the engine in your Gas car, I would still say that you would be a fool to add vegetable oil to your fuel. Teh engine will be toast in very short order. Veggie only works in a diesel engine because of the high compression AND injector spray. In a Spark Ignition engine, the injectors are not designed to atomise the fuel as thoroughly as a diesel injector does. The compression ratio of around 9:1 is way too low when compared to a diesel engine compression of around 22:1 You will have unburned vegie oil leaking past the rings and into the sump, where it will accumulate and rapidly polymerise. It is possible that this could occur in the time it takes to use one tank of fuel.
Add veggie to gas at your own risk!

A 10% mixture works fine in my lawnmover, but I would not put it in a car with a working catalyst.

It seems like a *really* bad idea ! My other project is a turbo-MX5, and some make efforts to *exclude* oil as much as possible from being combusted (via the crankcase ventilation ports), and for good reason (detonation, engine failure ...) In your case I'd question the ability of injectors to flow relatively thick VO.
Swap your car for a diesel and then go SVO/WVO crazy :)

VO is an excellent additive to gasoline for upper cylinder/valve lubricant. I also use it for bar oil in my chain saw.
