hi can you tell me what gearbox oil is for my impresa 1996 sti please also the diff oil

 

Hi

You need a 75w-90 GL5 oil for both.

The Millers CRX NT, Motul Gear 300, Red Line 75w-90NS and Gulf Competition are ideal as top end options. The Millers TRX Synthetic/EE Nanodrive, Mobil SHC, Castrol Syntrax Universal Plus and Valvoline Synpower TDL are good, but a step down from the top oils. Fuchs Gear Syn, Motul Motylgear, Millers TRX Semi and Castrol Universal are good, cheaper options.

Cheers

Tim
