How Much Unleaded Petrol Can I Get Away With In My Diesel Car Engine

This is a question we get asked on a daily basis and all we can say is it varies from car to car but as a guide to this question the answer would be around 5ltrs if you then fill the cars tank up with the correct fuel, some people will do this and risk any damage or engine failure.

Our advice would always be not to start the vehicle and have it drained out.
