So, all of this oil info has me thinking... Okay. I'm running M1 5w30 in the Cobalt now, after the car has been running QS right up until the current oil change (w/M1) For the next few oil changes I'll be running the case of PP 5w30 I picked up ( for the next 2 oil changes). I've been thinking that since the Napa syn is a great deal (picked up a case today), I might run it in the Balt too. Now, would going from QS dino to M1 to PP to NS be a good idea? The reason for my thinking is that the PP might do some extra "cleaning" of the other stuff (which makes me wonder if it will run low) I was planning th stick with PP for a while, but the good deals keep making me think twice....

ON, Canada eh?
Won't hurt it at all... Use a brand name that meets the specs (or higher) as outlines in your owners manual, for the cheapest price and you will be good!

The only area where it will cause some concern is if you do a UOA. It takes at least 2 OCI's to remove a previous brand's residual chemicals from an engine.
So it shouldn't hurt the Valvoline,then?

No, it won't hurt the current fill - you will have plenty of protection. It's just that traces from the previous fills maybe found in the UOA.

M1 seems to keep engines pretty clean. That, and if you've done regular OC's, there won't be anything for the PP to clean out. So run whatever you want, whenever!

\:\! I"m guessing if it does clean anything out, it will be the old QS dino...
