Loading ...My older son and I are going the “black diesel” route. We have 3 old idi diesel pickups which uses black diesel just fine. We centrifuge the used oil, add 20% gasoline for viscosity, and put it in our fuel tanks.
Rumor has it that the crude oil around here works fine also.. If we run short of used oil , I may have to get into the oil well location “inspection” business.
