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 M1 5W30 SN GF-5, contains some PAO, to one degree or another. Almost certainly less PAO % than it used to be in M1 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 PP and QSUD. IMO Mobil Super Synthetic 5W30 is more desirable than M1 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 M1 0W40 Euro Car Formula.
