Anybody use Royal Purple products in the wrangler ??

I am about to spend a bunch of money changing out all my lubrication fluids to "Royal Purple" brand and just wondering if anybody has used it in there rig ?? I have heard great things about how much it reduces friction, and some people even say that it helps with MPG. It is gonna cost about $200.00 bucks to switch out ALL lubrication fluids, but if it will add a long term mechanical benefit i think its worth it. My buddy says to use Amsoil....but i don't know much about either product.

I only use it for my trans (manual). Works a bit better than the OEM stuff in the cold (IMHO).

Got it in both diffs and Manual trany. Don't notice any significant improvements. Trany shifts a little smoother bout it. Piece of mind knowing you got top notch stuff in there I guess.

I used it to replace my manual tranny fluid a few months ago because my tranny was having a tough time shifting. Not sure if it was the fluid or just the main bearing going out in my tranny, but I'll be pulling the tranny out this weekend becuase it's toast. Getting it rebuilt and I'll see what the mechanic suggest as to what fluid to use.

I ran RP in my entire drivetrain the last two years and had great success. Drained it all this winter and replaced with Castrol Syntec gear oils because of financial reasons. I will say that while I don't really doubt the performance of the Syntec the shifting was smoother with the RP. The RP still had plenty of color to it when I drained it. You could prolly easily get away with 20K-30K intervals on the stuff.
