I agree it is fine for general use, but if I periodically push the engine at the track, the heavier weight would help, would it not?
Johnny is right. I wouldn't mix oils yourself trying for a better product. Also the 5-30 you are using should be OK for the track. See Johnny's post under,Racing section. It's the Daytona post.
