I've been a longtime user of Mobil 1 for many years in several cars. On my past car (before it's untimely theft), I've used Mobil 1 for all of it's life and when I took the valve cover off at over 100K miles, the cams, rocker arms, etc all were squeeky clean.
Now with the less availability of Mobil 1 5w30 (couldn't find any 5qt. jugs at my local wal-mart), I'm going to be trying Pennzoil Platinum. Now since Platinum's EOP base oil's properties are touted as being similar to Mobil's PAO and also Pennzoil's additive packs, could I expect the same engine cleanliness with Platinum as I did with Mobil 1's Tri-Syn and SS?
