Yes, as is Castrol Edge.

socal: I must, respectfully, disagree. Mobil1 used to state in their literature that they were a PAO ( GroupIV). Never did they identify Mobil1 as an ester base (GroupV). They have recently, from all research and posts that I have reviewed, changed to Group-III base, which is only processed petroleum oil, NOT A SYNTHETIC! Castrol won a lawsuit that enabled them to call their Syntec crap "synthetic," despite it being only processed petroleum-based oil. It is a travesty that Mobil decided to follow their lead. Mobil1 may have ester additives, but it is not predominantly ester. R/S, Greg
