This is what makes it such a difficult application. Most of the GL-5 oils that are great for differentials are corrosive to copper, and destroy the synchros.
The Porsche OEM stuff is quite good for this unique application, but my local dealer only buys it in 55 gal drums, and would not order me any.
The Red Line MT-90 is also very good, and synchro friendly. If you add in a Torsen type limited slip, it is just too slippery without blending.
