I remember reading in my old Bentley manual that there is a special grease called 'microlube' ? for greasing the splines on the clutch disc / gearbox input shaft but I havent got the manual anymore.
Could someone with the Bentley manual have a quick look for me and let me know the part number please ?
The local dealer has never heard of it

and can't find it on the ETK.
Cheers gents,
