ok well here's my dilemma, i purchased lifetime oil change at the dealership and they use mobile 1 synthetic, bottom line is that will be better for the car than regular mobile 1 won't it? but i do understand that RP is like top of the line and maybe in a couple years i'll trade it in for a Z-28 or a new SS cause i'll be makin more money and have quite a bit paid on my current car and when i do get a different car i won't buy the lifetime oil change again
