Put Pennzoil Plat. in a pretty dirty GDI engine at 121K. At 123K the oil was black. Changed it at 124.5 b/c I THOUGHT I smelled fuel in the gas. (Blackstone said different)
Took it to Toyota (free synth. change) and they used Valvoline MaxLife 5w30
Checked the oil at 2K (today) and its only a caramel color.
So did the PP clean up the engine so well that the Valvoline didn't have much to do as far as cleaning or
Does PP have a superior detergent pkg than MaxLife? So which might it be?
