Ok so I decided to run nothing but Valvoline 5w30 conventional in my 2009 gmc sierra 5.3 with afm, I change out that oil at 3k miles, no oil consumption, no irregular noises. Yesterday I dumped out the Valvoline conventional and refilled with 5w30 pp, and well so far I regret it, my engine has a noticeable tick now at start up, what do you guys think?
