So I just picked up a new Chevy Colorado ZR2 with a Duramax 2.8l turbo. Very sweet little truck.
I've always run Rotella T6 5w40 in all my cars/trucks. BUT this is calling for some proprietary "dexos2" oil. From what I can see, it's a new specification made right around the time this engine came to the USA. Is this just some marketing wank, and I can keep using my stockpile of T6, or am I stuck buying their licensed oil for 3 times as much?
