One thing that is pretty certain is using a quality oil made for gasoline engines, the "starburst symbol" you see on most oil containers, will be fine and won't hurt anything. As far as the diesel oil debate, it is personal choice and what people are comfortable with. There is one good debate though. Since diesel engines are not designed for high revs, you do wonder if diesel oil would provide adequate protection in a gasoline engine pushing 5k to 6k+ revs! I can see an argument there.

i use compatible to convey its rated & approved by the manufacturer for both diesel & gasoline engines... thats what the API rating means! remember that! & its recommended by anyone that knows about oil or engines in general... rotella-t has been recommended by engine builders for decades with zero problems. ive been using diesel oil in my classic pontiacs for 10+ years!

yes there are "stories" about diesel oil, just read this thread or many of the other threads on here & other forums... complete udder nonsense!

you must be the guy that posted the "high revs" thing earlier, where did you come up with that concept? a story you heard? there is no argument for that at all... diesel oil uses the same base stock oil as any other normal oils, therefore it can & will work exactly the same as "gasoline" oils. seriously, oils are not designed based on rpms, if it has an api rating it is "designed" for any normal rpm range. please show me where you got this "not designed for high rpm" mumbo jumbo.

edit: actually scratch that last part, if you seriously think or believe thats true, then its not worth wasting any more time on it. carry on.
