Need more selections of 0W-30 synthetics. Right now the only easy one to get ahold of is M1 AFE 0W-30, can't find the old GC 0W-30 anywhere. I'd love a Pennzoil Ultra/Platinum 0W-30 but that remains to be unseen except an even harder to find Euro grade 0W-30 Platinum. I just hope Mobil 1 keeps making it. Kinda concerns me that they'll one day drop it due to low sales as it doesn't seem to move fast. My local Napa and Carquest still have the old green cap quart bottles, some are old enough not to have the Dexos label!
