I did search but i don\'t like peoples Guesses on things like this (and i\'m using my phone to search which is annoying at best) just wanted to buy some whilst out, but i\'ll check my workshop manual when i get in.

I did this a few weeks ago, Rob is spot on, 2.5litres of 75W-90 is what went into my manual gearbox :)

I\'m pretty sure that you can\'t (or at least not easily), I ended up running a length of tubing into the fill hole, and squirting the gear oil in with a great big syringe... with a bit more forward planning, I would\'ve used tubing that was a little/lot bigger and just poured it in with a funnel :)

i got 3 litres in mine. i took the little dustboot off the top of the tunnel and ran a tube down to the fill hole through there. put loads of rags down on the passenger seat and sat there holding a massive funnel full of oil :)

The standard box runs with 2.5 Litres or 2.6 US Quarts
 
We run an Anglo American Oil.  It is a GL4 oil 80W-90, and designed to run in big horse power Japanese boxes.
 
Comes in quart bottles, so you will need 3.  Each bottle is £10.65 + VAT (12.25) each.
