Me personally....think all synthetics are going to give you the same HP gains given similar weights and ratings on oil tested for full synthetics. The other numbers that tell how well it is protecting your engine is more important...and you want a good all around synthetic not one that is very high in one area and then subpar in the others. Just my 2 cents...
if you are happy with it...then keep on...but better oils out there than RP in my opinion.

Yes...of COURSE there are better oils, but you're looking at upwards of 10-12$ a quart, and on top of that, can you even FIND these "better oils" locally?
