For the engine oil yes it is 10w50
I believed that bmw using the same 541 oil fiter that fits R nine T and oil cool engine.
For the gear oil and final drive oil that is my question.
I have been using the 75w90 on R nine T and R1200GS oil cool for many years without a problem.
Just wondering can i also use 75w90 for the R18 instead of the 70w80 that factory recommand?
Does anyone try that?
