Royal Purple Oils / Better Plugs
#3
If you switch to Royal Purple oils and have an oil related failure, it would likely be between you and Royal Purple for resolution - GM might not cover it.

I started out with Mobil 1 synthetic and last oil change switched to Penzoil Platinum Synthetic. The Penzoil seems to stay cleaner and last longer, so I may stay with it from now on. I changed the oil before I went to Kansas Speedway in July and have put on about 4,000 miles since then and DIC is at about 43% right now.
I also changed to Bosch +4 plugs quite some time ago. Seemed to have a little more zip after I did that. It's all a matter of opinion...and there are definitely a myriad of those here.
