Amsoil severe gear 75w110 GL5 fluid in a 1 quart pack (946ml).

This is our preferred oil for some extreme use hypoid transaxles, differentials and transfer cases.

Examples are most street / track rear differentials with or without limited slip differential centres such as Nissan R200, many Toyota models, as well as in some cases Porsche and Subaru 5 and 6-speed transmissions where gear protection is at a premium and a slightly notchier shift when cold is a compromise.
