[Cooch]

Hey guys wondering if you can answer the above question. I use to use Castrol Syntrax in my last car and i think it was 75/90 but what do FD\'s take? Also what Diff oil should i use? And how much of both will i need?
 
Thanks in advance guys.

The Castol will be O/K

Engine with filter change 3.5 Litre

Gear box 2.5 Litre

Diff 1.3 Litre

Cooling system 8.7 Litre

Fuel Tank 76 Litre

Hope this helps

The FB certainly uses 75W 90 grade and full synthetic (eg Syntrax) is great.
