Just bought a 2016 10k old GRiSO and want to do service of fluids and eventually grease everything but I’m a bit confused about a few things . As you can see I’m in Australia and have a contact at Repco. I’m thinking Penrite products ( upon reading Pete’s recommendations.)
1 , gearbox and diff 75W90 but semi or full synthetic - does it matter?
2 , fork oil, in the manual it looks like 5w - 20w. I’m after a plusher ride so I’m thinking more towards the lighter end - any comments please
And what is the story with levels, measured from top or quantity?
