Hi All. As fuel prices are becoming a joke, a mate of mine suggested using Vegetable Oil in my Diesel car. Initially i thought he was joking untill i did some research on google and there are plenty of various forums about it. For the last few months i have been using a mix of 50/50 oil to Diesel. I buy the oil at a rate of 89p a Litre (through bulk buy 10L drums) and the car runs perfectly, some people use a mix of 90/10 oil to Diesel but i have not yet been so brave. You are legally allowed to buy and use 2500L a year for using it as fuel since 2007. Any one else with experience of this? or use any other different types of fuels in a Diesel car? Regards.
