A mustang mag did a dyno comparison a while back and RP does give you a few more ponies. I used it in a brand new engine after it was broken in and beat the shit out of it till a piston let go. My engine builder was surprised at how good everything looked. The oil looked really bad to, he didn't even believe me that it was RP(Drove it pretty far with a bad misfire).
Oh yeah to your first statement. Thats completely foolish to think. So you are going to tell me using some napa brand crap is the same as mobile 1 or valvoline.
