The best thing to do if you're curious about the performance of the oil you're using is to send off a used sample for analysis (preferrably after you've run the same oil for 2-3 intervals in a row, in order to truly get an idea of how it's doing)

Doesn't 30wt always have the best wear/longevity numbers for all v8's except when it's cold?
As for Royal Purple...it may dyno higher when fresh...with the additive package is fresh...but wait and dyno it again with 3,000 miles on it and compare...
I've think under some conditions Royal Purple additive package that helps the hp numbers will breakdown rather quick.
I NEVER got a straight answer on this when corrosponding with RP about two years ago.

Although in a few months they will be releasing a new 0w30 racing oil which will most likely be closer to the top end of the 30wt range, plus they are also coming out with a 5w40. So stay tuned, Mobil 1 might have a couple of winners on their hands.

10w40 in the summer here in houston and 10w30 in winter....car made over 430 on mti's dyno even with 110,000 on the clock..DON'T SKIMP ON THE OIL AND KEEP A FULL 6QTS in that sucker....no matter what the manual says..when ur pullin wheels at launch u loose oil pressure....if ur worred about the 5hp loss due to the extra oil ur in the wrong bidddness.....
