I have a 2007 Chevrolet Cobalt SS Supercharged and I picked up some Valvoline SynPower 5w30 for it I was just wondering if this is a good choice for the car.
Definetly. I don't know if the superchaged Cobalt engine requires a 4718M oil, but even if it does, Synpower is 4718M certified, so you're all covered!
I know the Turbo Cobalt SS requires 4718M oil. Buddy has one, and runs M1 5w30 in it. It goes like a scalded ape!
