Goodbye synthetic oil... we hardly knew ye
Check out THIS THREAD on the Xterra Owner's Club forums. I hope TJ is wrong... but I suspect that he is not (he's shown himself on the forums to be very knowledgable and helpful... this isn't coming from some rumor-spreading punk).
I think it's time to switch to Amsoil.
ETA: Summary: If this info is correct, market competition (Castrol = jerks) has driven everyone to stop making higher grade synthetics - they're now giving us slightly improved dino oil and still slapping that Mobil 1 full synthetic label on it.

I thought everyone knew this, as it is 7-year-old news. Here is one of the best overviews of motor oils I've ever read, even though it is from a motorcycle perspective.

Well, I still use Mobil 1 and suprisingly my engine hasn't blown up?!? Who would of thunk it? 
I ran sustained near 300F oil temperatures at TWS and MSR with my old C5 running Mobil 1 and never had an issue. Must not be that crappy of an oil.

It's funny the Xterra owners are worried that M1 isn't good enough. haha. Like the V6 or older 4 bangers in the Xterras are subjected to race-track levels of abuse. Unlikely.

I use the good ole castrol dino juice for the RX8. 5 quart jug at 8 bucks and the car drinks it happily. I'm enjoying the 15 dollar oil changes after the M3 used 8-8.5 quarts of Mobil 1 at a time.

Good point about it not mattering much in an underpowered X.... I actually run Valvoline syn in mine for no particular reason...
From reading the article that TypeSH posted, it is clear that the type 3's like Mobil are sufficient - but I have two problems:
1) It's deceitful to lessen the quality of your product without being open and honest about it - even if it is still "good enough". Mobil started out as the good guy in this saga by sueing Castrol - but by caving and changing their product on the sly they became just as bad. Integrity matters a lot to me and I just lost faith in that company.
2) I wanted to put absolutely the best thing available in my S because it revs so high... I thought from what I've seen that Mobil 1, Amsoil, Redline etc were all on the same level in terms of quality - turns out that is not true and both Amsoil and Redline are better than Mobil 1.
