92 Yukon w/ new 5.7 engine w/ 20000 miles on it: Engine Oil?

[TerryKing]

Hi Everyone,

I have free access to some Shell Rotella T4 oil 5w-40 which is high quality recommended for diesels.

Any reason I shouldn't use this in my regular GM350?

Thanks!

Ive had nothing but amazing results from Rotella oil in all engines. Love the T6. I wouldn't hesitate running T4 in one, either.

Yeah if it's free and ethical, like maybe a perk at your job or something, I'd run it.

Rotella is a great oil for diesel or gas engines.
