Someone gave me 5 gallons of diesel fuel contaminated with about 20% gasoline. Is it safe to run this through a diesel engine if it gets diluted into a 35 gallon diesel fuel tank?


20% is a bit much. If it was a weaker mixture you could drop in a can of 2-stroke oil to make it useable. Diesels are more sensitive to blends like this than gasoline engines. It can pre-detonate and make a BIG mess of your enginebay.
