Is it true that waste vegetable oil can be an alternative to gas&diesel to run an engine?
Yep for Diesel it can, you can simply put it in the veg oil with your fuel 50/50 In the winter it is better to change the ratio 70/30 diesel to oil….due to the cold changing the consistency of the oil My mate does it with his transporter van, it really works and you only smell a little like chip shop…th strength of the smell depends on the condition of the oil!!!!
