Apparently in the North of England people are running their diesel cars on vegetable cooking oil. Nothing would surprise me about people up there. They’re still pointing at aeroplanes, but…
There was a BBC demonstration of how this is done. (I am not recommending this – it may well be very stupid)
On the programme (top gear) they showed it was done as follows: Get and filter some used cooking oil (it has to be used apparently) and add turpentine at a ratio of 997/3. Drain the engine of diesel oil, add the vegetable oil and drive away. Appears to run perfectly.
Cost of running car on chip fat about 5p a litre. Cost of running car on proper, taxed diesel about 60p a litre.
Can this realty be true? Is it possible to run a diesel car on cooking oil? If it is, why aren’t we doing so, surely vegetable oil is a cheap renewable fuel?
