royal purple

[blk_srt]

i did some searching and i didnt find anything about it so here it is. Has anyone switched over to royal purple in their engines, tranny, and or rear diff for the awd guys? I did some research and on average the got about 9 extra hp by running royal purple, I was really wondering if it would be ok to use royal purple in the tranny and rear diff?

I hate to state the obvious, but if you just plan on putting it in the tranny and rear diff., you won't see a hp gain, so I hope that is not your intent. If you plan on using their motor oil, chances are you will get a few ponies out of it because of the quality of the oil, but then you chance leaks because it is synthetic, and a very liquid-like one at that.

It will, however, run smoother. Those guys that make that royal purple shit know what their doing, and charge a lot for it.

BTW, no, I am not using it, but like you I did my research before making my decision. Wasn't worth the risk to me, my car had 55k at the time, and I would rather not deal with the possibility of leaks.

the reason you see gains by putting it in the trans and rear diff is because it has less friction so there isnt as big of a hp loss through the drive train, granted its not going to be alot but anything helps right. as far as the price its only about $1 more than mobile 1 which im running right now with no leaks what so ever. all i really wanted to know is will it be compatible with the tranny and diff because i know it takes a cirtan kind of fuild for a reason, I just dont happen to know off hand what that would be
