As for the longevity of Mobil 1, I don't know how many people here got their oil tested or were just going off the assumption that synthetic oil can last forever but i got mine tested by Blackstone and @ 8,400 miles(mostly easy highway miles) and the TBN was 3.8 which means I'd be pushing it going to 10K. Those tests for Mobil going for 100K+ without oil changes, i don't buy it. There are some oil companies that claim to make a "lifetime" oil but i have yet to see real proof they'll do what the manufacturer claims. I do highly recommend synthetic oils and lubricants but they aren't a failsafe for anything.
