M1 is currently on rollback at WM so I'm thinking of running M1 5W30 for my summer fill and switching over to the PPPP 5W30 D1 Gen 2 for the winter . Conversely , I could just run one or the other all year long (Georgia) - the main interest for me with the PPPP 5W30 D1 Gen 2 is with the improved timing chain protection - all the other specs the M1 10W30 probably meets anyway (LSPI , etc.) which again I don't have a turbo in my GDI engine ... Your thoughts on what you would run ?
What dos NOACK have to do with anything?

** Less oil vapors / evaporation through PCV , etc. would supposedly mean less deposits on intake valves .
