So what I'm gathering is, I should play it safe, return it and get 5w-30.

RP used to be the best of the best. Last oil report i bothered reading (about a year ago) RP was 3rd. Amsoil #1, Mobil #2. The rest of my family runs amsoil, it seems to burn off faster. Brothers car went through 3 quarts in about 3 months. I topped it off with my mobil 0-30, he hasn't lost a drop since.
blown transmissions are about as useful as 97% of the guys on this forum
Race motors arent usually tighter than a stock motor. If anything, they run more clearance and use heavier oils. Not trying to start an argument, just sayinOriginally Posted by 6.0vortecchevy

From what I've read it's not really GMs idea to recommend 5W-30. It's another EPA thing. 0w-30 and 5w-30 use less fuel on startup and has less emmissions on startup, so GM is forced to recommend it. Personally I don't live in a very cold climate, so I don't use it. I usually use 10w-30 or 10w-40.
