ynots57,
If you were talking to me why no I don't use 2 cycle oil. The reason is I don't like the loss in fuel mileage up to 2.25 mpg nor the injector problems I had while using it. I'll repeat what I've said many times not all 5.9 2005 and up like 2 cycle oil but if it works in your engine that great and if not try something else. My engine does not like 2 cycle oil nor does it work in many other peoples 2005 and newer trucks I talked to on other forums.
