Royal Purple (or other synthetic) for rear?

[Anaconda]

Just wondering if anyone uses a synthetic like Royal Purple in the rear end? Supposedly synthetic gear oil adds a couple RWHP. Is this true? I need to get mine changed, and if I can add a couple horsepower in the process, I might as well go synthetic. Any advice? Thanks.

I use Mopar. 6+ years tracking, no problems.

I was told to stick with the mopar dinosaur fluids and the mopar limited-slip additive...

any place carry Mopar fluid other than dealer?

Isn't the stock Mopar fluid synthetic?

I know the Mopar fluid is the "recommended" fluid, but I heard that switching to synthetic is worth a couple extra RWHP. My question really is...can I switch to Royal Purple (or whatever) with no problems, and gain a couple extra HP?

You missed my point. I guess I will make it more clear. The OEM fluid IS synthetic. Now is your question will a different brand of synthetic make you usable horsepower?

I have Royal Purple in my rear right now. No problems.

Sorry, you asked if it was synthetic, which led me to believe that you didn't know.

Mopar is definitely synthetic.

Maybe for you but I would think that stuff would itch
