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.
