Recently bought some Motul Motylgear 75W90 Gearbox/Differential Oil. I had planned to use AMSOIL 75w90 because it was specifically GL-4, as I heard GL-5 can harm the transmission of my car specifically the yellow metal syncro. (98 240sx stock KA motor / tranny). So instead I bought some Motylgear and found out its both GL-4 and GL-5. o_O

Was wondering if anyone has used this motylgear 75w90 gearbox / diff oil and if its GOOD and wont damage syncros. I plan to use this in my transmission and vlsd. The store owner I bought it from said it would be fine as he ran it before, I just want some confirmation. Thanks

(Also not to be confused with motylgear 300 75w90, which is not the one I got)
