From everything that I have read, the AFE formula changed not so long ago and the amount of PAO was reduced so it could be argued that is not as good as EP. I still have some of the "older" AFE that had the Ford 5W-20 specification on it and it performed the same as EP in my F-150. Mobil really does not make bad oil (though Mobil Super Synthetic does not really fit in the line up), so you cannot go wrong with any of it.Is the AFE close to the others?
With that said, any of the modern synthetics carrying SN or SN+ specifications are going to be hard to beat and to compare to easily know which is "best". I like the titanium add-pack in Castrol, so I use it, but I have had good luck with M1 and Pennzoil.
