My question is.... what is the difference between the various Mobil 1 Synthetic oils and the Mobil Super Synthetic that is on sale at Advance?
Is it just marketing?
IMO any Mobil 1, even the regular Mobil 1 5W30 SN GF-5, contains some PAO, to one degree or another. Almost certainly less PAO % than it used to be in Mobil 1 SM. Personally, I think that high concentration of quality PAO is beneficial for driving in Arctic conditions and when racing on the track; otherwise, go with some sort of dino: 1. conventional, 2. syn blend (advanced dino), 3. Group III synthetics (glorified dino). The most well known Group III synthetic in North America is Pennzoil Platinum 5W20, 5W30, 10W30. I believe at this time that Mobil Super Synthetic is comparable to Pennzoil Platinum and Quaker State Ultimate Durability. IMO Mobil Super Synthetic 5W30 is more desirable than Mobil 1 5W30, base oil wise and detergency wise. $20 for 5 qt of Group III synthetic is a very reasonable price. IMO if you are going to run a mainstream Mobil 1, go with Mobil 1 0W40 Euro Car Formula.
