I must say though, when it comes to my 'maro then I will be changing the oil more frequently, and with better quality then I have before. I hear royal purple is good, and good things about mobil1.

I had a 2007 G5 GT that went over 100K miles (traded it in on my Camaro) and the oil was changed when the monitor said to. Usually got better than 13K miles between oil changes, and it was NOT synthetic oil. G5 GT oil monitor recommended not using synthetic in the car.
