I am running it now for my recent oil change...and i do notice lower temps...but get ready for a snowstorn of opinions tha t will have your head hurting from all the different ways people look at things...lol.
I am giving it a try...there was ALOT of negative press...or claims that were unsubstantiated...but decide for yourself.

I have noticed lower oil temps.

Others have noticed smoother shifting in their trannys.

Let the storm begin...

I use RP in everything including the daily drivers, the lawn mower, snow blower, etc.

Draw your own conclusions. Feel free to take the below linked AMSOIL commissioned study with a grain of salt. Even if you through out the AMSOIL results, its still an interesting read for those interested in why one fluid is different than another.

Don't think you can go wrong with the RP. I am running the RP Maxgear in my rear diff, Redline D4 in the trans, and Mobil 1 in the crankcsae. No issues.
