Hi folks, going to change the gearbox oil and rear diff oil in my 05 blobeye,

Have searched and found that 75w90 goes in the diff. Is it the same oil for the gearbox? Also what brand do you guys recommend? Fully synth or semi?

Cheers

The Castrol website recommends Syntrax Long Life 75W-90 fully synth, which is what I use in the gearbox and diff.

+ 1, I use the same too, no problems yet, but only 33000 on the clock.
