[QUOTE="Jimmysidecarr, post: 10787933, member: 11681"] I have hands on, what about me? What about Scott Whitehead former Ford durability testing engineer guy? He's got more credibility on this topic than any of us, are you saying he's full of crap too? Did you even bother reading up about him and his advice? If you are driving like a grandpa at stock horsepower and you have already switched to a high quality synthetic, you probably will be fine with the 5W-20. If you are running less than full synthetic and using 5W-20, then it's the next guy's problem who buys the car anyway... right?:nonono: You can run what ever you want, but you should be a little more restrained about trying to discredit people who are attempting to shine the light on a KNOWN and verifiable 5W-20 engine longevity issue. We are doing it to help people and that it all. I make the same pay whether people run 5W-20 or 5W-30, I have no reason to give wrong or false information. I do not understand your motivation for so vehemently challenging assertions, that 5W-20 is significantly less than an optimal oil when used as a conventional or inexpensive synthetic blend in such a high powered engine application.:shrug: [/QUOTE]
