I agree RD its the flavor of the month.  I am looking more of what to stay away.  I mean I could run regular 10w40 oil from jiffy lube and never have a problem.  Its a pretty whacked subject.  Everytime i do a search I come up with negative stuff on any motor oil.  Just put the pharase "don't use" in front of the oil.  Ie the link below is the latest.

Good Frickin Grief.  I think I might just flip a coin!!  hell if my engine does blow, then I can put a 3.8 in it for only $26,000.
