I have read a few posts where people bad mouth Mobil 1, and others love it. Has it gotten better??
I used it a few times in my new truck in 2001. It seemed to work as claimed. But in 2002 Mobil must have changed the formula with the Tri-Synthetic (Try to be Synthetic???). When I did an oil change with the "NEW" formula, I noticed that ALL 6 of the quart bottles had dark sediment on the bottom. I cut the bottles open and the sediment looked like parafin. It didn't feel like grit. I could rub it between my fingers tips and it would turn them dark brown/black. I contacted Mobil 1 a few times to ask what the sediment was from, but they never got back to me. I was 100% sure that synthetic oil could NOT have sediment in the bottle. After about 1,000 miles and never getting a responce from Mobil, I decided to drain the M1 Try-2B-Synthetic and ran another brand (Syntec). I have not used Mobil 1 since that time.
I later read where Mobil and Castrol were sueing each other (or filed a complaint with the FTC) because neither one was a real synthetic, so I stopped using Syntec also. Now I'm using another fake synthetic Q-*
