Took the head off once to change the gasket and the engine looked like brand new inside. No browning of the metal surfaces, the cylinder walls still had the hone marks on them. I was sold. I never put anything else in my vehicles since and I have never had an engine failure.
With the exception of my 55 Chrysler Poly. I have been worried about the zinc issue but the performance of the Mobil 1 has me wondering why wouldn't this oil work in the 55 Chrysler? It has excellent characteristics, lasts twice as long as normal oil, (you only change it because it's dirty not because it is ineffective at lubrication). Why wouldn't it be just as effective in an older engine without the Zinc additive?
