I completely trust HPL, the other premium products and the knowledgeable people here.
However, I am fond of "getting the dirt out" of an engine....especially one which ups the temps significantly...namely, turbos.
I understand that the modern, verifiable, established sciences behind lubrication tech are "the cat's meow", but you're still pumping oil through filters which exhibit wild swings in construction soundness.
They always say new engines tax oil more AND that oils have been improved accordingly. But, is the spec oil you need always available?
The dealers seem always to use their cheap, bulk oil in everything <<OOpps, there's that "dealership hate thing" coming up again.
