Amsoil severe gear 75w90 GL5 fluid in a 1 quart pack (946ml).

This is our preferred oil for some extreme use or coarse tooth high-pressure angle synchronised transmissions, and also many hypoid transaxles, differentials and transfer cases.

Examples are PPG synchronised gear boxes (Skyline 5-speed); Evo 4-10 transfer cases and rear differentials; Subaru 5 and 6-speed synchronised transmissions and rear differentials, and many other applications.
