I recently bought a new to me 2017 R1200GS. The owners manual oil specification call for SAE 5W-40, API SL/JASO MA2, Additives (for instance, molybdenum based substances) are prohibited, because they would attack the coatings on engine components, BMW Motorrad recommends BMW Motorrad ADVANTEC Ultimate Oil. Since this was a dealer demo bike it's covered by the full BMW warranty. I would like to use an oil that complies with the specs, but don't know about the additive specifications. Any suggestions?
