Oh you did? did you read my first link? Scott Whitehead one of the engineers that designed the s197 actually states that the 5w-20 was made for cafe standards. Why dont you all just go to blackstonelabs order a free oil analysis kit and do your own oil analysis like some of us have so you can decide if 5w-20 is working(which it wont). The 5w-20 for clearance is primarily 90% false, yes it has tighter clearances but it does not require 5w-20.

Your probably right i dont know and i dont really care to much. I put in 10w30 and i thought it was fine until someonetold me otherwise. Either way im sticking with the manual. I mightchange to 10w30 after my motor build.

I really hate these 'What Oil do I use' threads. There is no consensus and they always turn into arguments. However I have to weigh in here since Androdz2brought it up. I too have heard Scott Whitehead wax on about this. It made me switch from 5W-20 to 5W-30. For those of you who don't knowScottis a former Ford engineer involved in the Mod motor design, a current driver in the NASA-AIX series, he wasthe crew chief for Rehagen Racing Grand Am team and he is an engineer on the Michael Waltrip Sprint Cup team. He has been quite clear on the subject and does not recommend 5W-20.

It's funny how fast the recommendation changes when CAFE concerns are no longer a factor (they get gas guzzler taxed anyway). Roush also recommends 5w-30.

RE: Synthetic Oil Question
I highly doubt you'll ever see a tangible difference in using any oil brand mentioned, synthetic or otherwise. Therefore, pick the one that has a pretty bottle, lol. I've run synthetic, blends, and dinos in a variety of cars over the years and I haven't a shred of evidence to support any of them impacting the vehicle negatively. My personal opinion is to keep to a reasonable change interval for your chosen oil, and most importantly use a high quality filter.
