For the gearbox you will need 75w-80 or 75w-90, the VAG spec for your car is G 052 911 and we have always had good results with the Fuchs Sintofluid 75w-80 Fuchs TITAN SINTOFluid SAE 75W-80 Syn Manual Gear Fluid As for capacity the 01E gearbox is 2.5ltr and the 02X is 3.5ltr.

Well, I took my time about it but changed gearbox oil about 6 weeks ago, definitely could feel smoother gearchanges after changing gearbox oil. Today changed the rear diff oil and it does feel as though it has had a cushioning effect on the amount of vibration felt, particularly so at low revs.
