Running a diesel on vegetable oil

[Chris71]

Can someone give me an idiots guide to this?

Is there a rule of thumb for which cars are suitable. Is it basically that any car with the old mechanical 'unit injectors' can do it and the more recent electromechanical ones can't?

What's the process - do you just need to premix the vegetable oil with a given quantity of something to thin it down, then into the tank?

Finally, can someone give me an idea of the benefits - a rough comparison to petrol costs for a given MPG, for example? The car I'm quite tempted to try it with is a 306 D-Turbo.

The price of veg oil is now much the same as the price of diesel. Run it 50/50 and it should run smoother and cleaner. Always carry a spare fuel filter as they clog up twice as quick with veg oil use.

What car do you intend running it on?

Just something I was mulling over. The most likely candidate would be an early (pre-Lucas) 306 D-Turbo though.

Are you talking pre-tax or something with the above? Surely if the 'forecourt' price of the two was the same you'd be better of with diesel?

The question is.... does it actually save you that much? I've heard people saying that veg oil is now almost up to pump diesel prices? Surely this would defeat the option?
