Morning all,

Bought some Nulon Full Syth 75W-85 GL-4 rated oil to do a gearbox service, but the manual states 80w-90 is preferable for <40 C.

Seems pretty close but thought I'd just double check!

Good to know. Want to change the oil in my gearbox too, as I have no idea how old it is.

Can confirm it fine with 75w-85 and it running smooth since the change.
