Penzoil is excellent oil based on all the VOA's (virgin oil analysis) Ive seen in the last ~20 years... when did you use it, 40-50 years ago when you first started driving? I have used penzoil off & on since 30 some years ago with no signs of what you mentioned and have used it in recent years with zero negative issues, about to do a change on my daily with it in a couple weeks, will report back if my oil psi drops A LOT or at all.

Penzoil meets the same API specs as any other oil, aside from some specialty oils all name brand modern oils meet the same API standards as they are updated. Based on the Shell engineers comments, penzoil or any other oil is OK to use because it meets the API standards...

Obviously I was exaggerating about gold colored piss water to make a point. That we don't know what their display is really comparing. Anyone that's impressed by that display can do so freely. That display proves nothing to me. Good oil should have sufficient film strength inherent to it's design. That's my belief. How well does "sticky" oil drain back to the crankcase? That's another concern I have with the theory. How does it affect the detergent action of the oil? IDK. I'll start shopping for additives the day I see a clear performance deficiency with oil straight out of the container. The stuff is expensive enough to start with.

I started driving 40 years ago. I agree that Penzzoil may be completely different now. The specs were lesser back then compared to other brands. I haven't checked lately. But, back then, some oils met higher standards than others. So there was a clear linkage between my observations and the API rating.
