M33 Primary Chain Case Oil

[Mr Jones]

Hi,

Have read a lot of sometimes conflicting info on what is the best primary chain case oil to use. ATF or not?.....

Cheers.

[Mr Jones]

And while we're on the subject, best gearbox and engine oil?....

I use 10 or 15 grade fork oil in chaincase and 40 grade Millers in the engine. Millers 50 grade in gearbox on my 49 M33.
