  1. Anyone no  how much gearbox oil the f40 takes Thud
on the vxr it's recommended to use 2.4 litres, normally 0.4 litres remains in the gearbox during an oil change - so just add two full litre bottles
Thanks for that .loads of different figures about on this was told 1.9 liters for f40 think I will drain it and see what comes out
Normally you have 2 bungs a fill and a drain, it used to be you drain it through the drain bung refit it the fill through the fill bung untill it starts to dribble out and hey presto you have the right amount of oil in. I don't know if this has changed though
Hasn't it got an oil level plug where you fill it until it piddles out?
No its got drain at bottom and fill on the top
F40, ive read 1.8, 1.9 and 2.0 put in.

Im going for Millers oil 75w90 instead of 75w85, prob 2 full bottles (2L)
There is a thread with info on how much oil you will need.
