So I'm bored at work and been reading about Gear Oils again.. (Its a Quiet Day So sue Me :P)
Now I read somewhere that the Gen II MPS now has factory oil reccomendation of 70w80 as opposed to 75w90
This is supposed to improve the cold weather performance of the gearbox and make it smoother.. Wether or not this is at all valid I haven't a Clue. But I thought a thread for purely informational purposes would be good for the Wider community.
Is there any validity to what I have read above regarding the difference in cold weather performance.. or just over all smoothness of the gear oil...
Or is this all just another Wives tale/what have you?!
