I think Mike misspoke / miswrote
Most gear oil is GL5 and it is GL4 that is hard to find
But the best oil for the ZF is Red Line 75W90NS--- the NS signifying "not so slippery" I presume.
ANY oil that says it is OK to use in a limited slip diff will be TOO slippery for proper synchro function and will predispose to early synchro wear.
GL4 oil is better for "yellow metal" gears but this is a fairly minor consideration in comparison to better lubrication for the diff portion of the ZF provided by the GL5 Red Line 75W90NS
At least this was the conclusion reached by the ferrarichat group for use in "brand F" transaxles.

Mike,
I thought GL-4 was the recommended oil, per Lloyd's website "FAQ" section. Did
I miss something?
