And it should be "Noack", not NOACK. It is someone's name.
I tend to agree. How much better is 7% than 13%? No one really knows where the threshold is. Driving style, fuel quality etc, all contribute to an engine's wellbeing. There are quite a few forums with angry members who "only used the best, low Noack Synthetic oils since day one" who now need a walnut blast.
Agreed. That said, how important is all the other stats that the obsessed love
to obsess over? That is the question. As the other Zee suggested I'd rather buy a 8
Noack oil than a 15 one.
