In the past 30yrs at dealer I've seen at least 5-10 cars a year with gas instead of Diesel, haven't heard of or seen any engine damage due to this prodcedure. It sure will remove alage from tank. This fuel blend sure doesn't run good in most gas cars either!! Several techs had their gas cars towed in from being CHEAP & trying to reuse gas/diesel blend.
