Does anyone use synthetic lubes in their trans and rears? Was wondering about about problems such as seal leakage.
I use Valvoline synthetic fluid in the Cougar's rear. No problems thus far....
I always use Royal Purple in the rear, this is my first time using RP in the trans, no leaks.
Ill be running royal purple in both my rear and trans here soon too.
I've been running Pennzoil Synchromesh in my T5, but I don't know if that's synthetic or not. Can't remember.
