Ok, here's the low down on oil. If you are a Stock, Super Stock or Comp racer you're goal is to make the most HP without causing damage. Finding that spot with your combination is like finding the perfect clutch set up in a stick car or the perfect converter on an automatic car.

Is there HP is one oil over another???? Yes but just changing oil is not where the real gains are at. What you are looking for is the thinnest oil that will provide the lubrication and cooling properties you need. The real gains are in being able to run the lowest oil pressure with the minimal amount of oil in the pan reducing HP drag on the pump and windage in the pan.

In Ed's defense I will say that Mobil 1 (Extremely low viscosity) with a certain additive (I can't tell you the name) was the best at all of the above that I found. My SS/A Corvette went through the lights with the oil pressure gauge dancing between 40 and 60 lbs. You had to clutch it and shut it off immediately or the oil pressure would go to zero when you hit the brakes.

When I sent my Comp engines back to Houston to be freshened (every 30 to 40 passes) the guys in the shop would drain the oil and say "What the hell is that?" The oil drained out of the pan like water.

BTW, I've never had any lubrication issues with bearings, valve train or cyl walls. Many of the people on this forum could find additional gains of .02 to .03 or more by working this method. It's definitely worth it if you are looking for every .01. Take it slow and check the bottom end.
