evaluate this quote from another message board:
quote:ive heard from two people on this message board that mobil 1 doesnt use a group IV basestock. ive argured that mobil 1 supersyn is a PAO synthetic unlike the other group III pretenders. from what information ive gathered on this website, i figured that mobil 1 is a high quality oil but others on this website do not believe so. any input is appreciated.
I actually emailed a rep from Mobil a while ago when the new trisyn formula came out and he told me that it wasn't 100% PAO stocks. I guess Mobil must have changed the formula back to PAO for their synthetic oil after all the bad press. Also last I heard about Mobil(from Bror Jace) was that his car started showing signs of piston slap..... which never should have happened while using a supposed high quality oil like Mobil 1. Well, you learn something new everyday, but I'm going to wait for more good reviews about Mobil 1 before trying their new formula.
