John, I drained my OEM oil in my 2007 V-6 at about 1200 miles and went to Mobil 1 5W-30 with a Nissan filter.  I now have 12000 miles, truck runs great and burns no oil.  I was very fastidious during the breakin period and followed the owners manula recommendations.  Big believer in that.  I think a proper breakin gives engine longeivity.

Lots of good syn oils out there.  Many cars actually come with syn oil from the factory nowadays.  I also changed the rear diff fluid to Mobil 1 after about 5000 miles.  Good idea to do that after breaking in the gear set.  Also did the front diff and transfer case with the proper fluids (see your owner's manual for proper fluids).

Lots of good Amsoil comments and good comments about Mobil 1, Pennzoil Platinum and other oils.  Really a great way to educate yourself about motor oils.

The only reason I never used Amsoil is their crazy sales system.  It is like Tupperware.  I buy and use Mobil 1 in 5 quart jugs from Wal Mart.  Right now many synthetic oils are in very short supply because Hurricane ike severely damaged the reactors that Exxon Mobil has.  They supply syn base to a lot of other oil companies.
