I was just wondering what everyone thought about this new oil. I personally used Mobil 1 Extended performance. I can't seem to find a oil analysis on it either.

The old PU had a low low, NOACK , near Amsoil or Red Line. It ran clean.

I expect the new PU, PUPP, (Platinum Ultra w/ PurePlus) to be even better, inspite of it's higher NOACK.

As someone who drives 100k miles per year and 600k miles per engine/vehicle, I am concerned about two things: intake valve deposits and piston ring coking. My 2 million+ miles of experience has taught me that. For me, PUPP will shine, unfortunately in 5W20.
