I use 10W30 Amsoil and have seen around a half tenth from it (over conventional racing oil). It holds up very good in a daily driven/strip car. Running oil that is too thick just robs horsepower cause your engine has to pump the thick oil.

[QUOTE=BLK02WS6]That is true for a short usage, but you don't wanna run it in a daily driver! The 0-30 will not hold up to daily usage - I just read a test on that recently. Those who use the very thin racing oils change their oil VERY frequently (like after each trip to the track).
I run the Mobil-1 0-30 about thirty passes betwean changes without any bearing issues. The oils that you need to be really careful of are in the 0-10 range and are, in my opinion, only good for a couple of passes.
The main reasons that I run light weight synthetics are;
1. Superior oil film to regular oil.
2. Less windage.
3. Faster drain back.
I never run more than four quarts in my LT1 Stocker motors which go thru the traps at 7200 rpm. As a side note my 2003 Mustang had 5-20 oil from the factory.
