Soooo, are you saying it is approved to run rotella?
additives are different in 0w40 and 5w40 because 5w40 is diesel oil, that is why there are a lot more options, it is everywhere.
rotella can put 1,000,000 moles on a cat engine so why wouldn't it be good in ours?
I just always used Mobil 0w40.
And with these damn disposable engines, i want what i can get most mimes out of.
not like there are parts for these engines to make it worth rebuilding or upgrading...
