Have been using Ultra Platinum 5W30 for several years but the lack of Dexos1 Gen2 certification is concerning since I have a GDI engine with timing chain. Pennzoil has reformulated the Platinum 5W30 to meet D1 G2 and am looking at that to replace the Ultra Platinum on the next oil change.
Any user comparison of old PP/PUP and new PP D1G2?
