I agree it would have to be at the very least not detrimental to GM's quality levels. Which is why I said any quality name brand oil that meets their recommended specs should be fairly close to the same. when you start naming names like Mobile 1 and Penzoil and Amsoil those companies aren't going to let another get a large advantage atlest not for any signifigant length of time.

I've heard that the only reason GM uses 5W-30 instead of 10W-30 is to help their CAFE numbers (if it is a few tenths of a mile on every vehicle, this is a huge difference for GM).

doesnt GM own part of XM? Or am I thinking of Onstar..... I do agree with you in the mobil 1 thing; its a huge marketing tool for mobil cause GM has the Mobil logo on their oil caps and in the owners manual.

Just a quick question regarding the oil change process. If I change my oil on my own, will it void my warranty? If not, do I need to keep my receipts?

Keep receipts. It won't void your warranty...

I noticed that also.. I built a 4.3 a couple of years and put Royal Purple in it and after a very short time the oil turned tan/brown.. I was disappointed that it lost its purple color especially in a clean new engine..
