If you live in Hell, the 20w-50 works fine.racer7 said:Have no idea what you have available locally at decent prices.
For myself, I use the BMW synthetic 15W-50 for ranges like that in an R1200 and change intervals of about 7K miles.
The 20W-50 dino juice is a bit of an impediment to cold cranking with a stock battery and the synthetic provides little relief..
You can of course use any motorcycle rated oil of proper viscosity. Modern cars oils are not ideal- less protection for sliding contact valve mechasims found in bikes- cars have generally gone to roller rockers and less ZDDP, etc in the oil to extend catalyst life.
Certainly understand where you're coming from. However, my decision was to provide for the OEM and the dealer network by actually purchasing the bike for $17K+.patsmith said:Buying non OEM parts does nothing to help fund the R&D and other functions of any OEM, nor does it help the finical health of the dealer network.

Good theory, but I am pretty sure that BMW don't make filters! OTOH, I have heard (not verified) that Mann supply the oil filter to BMW!patsmith said:Buying non OEM parts does nothing to help fund the R&D and other functions of any OEM, nor does it help the finical health of the dealer network.
