Synthetic oil in rear

[Livnn]

Thinking of changing the oil in the rear, to a Synthetic oil any thoughts or suggestion, thank you Livnn

I used Royal Purple gear lube with good success. Additionally did not have to use (as much) friction modifier.

Why? The only reason to change to synthetic is that it can handle high heat for long periods of time. That means open track road racing. If you're not racing, there's absolutely not advantage at all. The only thing you'll accomplish is to make your wallet lighter.

But, if you are racing, I suggest Royal Purple. That's what I use.

I use the Royal Purple, why not. I may go racing!!! and I won't need to change it.
I did go to my first autocross this weekend, but I know what you mean Bob.

First time autocross can be humbling experience.
