OK ... this may be a dumb question and before someone suggests RFM ... I already checked the manuals for both my 2016 RT and 2018 GS and neither has the recommended final drive oil spec. I have been using BMW C-SAF-XO 75w-90 API GL5 but a buddy with a new 1250 RS says his manual recommends GL3 ??
He was asking me what he should use and now I am confused and wondering if I am used the correct final drive oil.
Thanks in advance !
