Hi Wilgil,
the engine of your bike is designed to run on very bad oils, infact, today is very hard to find oil on marked to unfit your Tenere. That means that you can use almost every mineral oil, but always care to look for oil for motorcycle use because of aditivs added for wet clutch and gearbox. But, there is a several reasons to use better than mineral, I could say that semisynthetic oils are optimum today. If use simple mineral oil, count on longer warming up period ( around 15 km ) and evaporating of mineral base is always higher compare to sint base, so that somethimes results with higher oil consumption. I always use 15W-50 esther blend oils, mostly Motul or Silkolene, after years of researching. Also, after 6000 km on my XTZ 660, Motul 5100 seems in very good condition, no black to much, like almost nothing happend in this 6000 km, engine took no oil, apsolutely nothing. Otherwise, when use mineral oil, engine takes aprox. 0,5-1 liter / 6000 km, which is normal consumption for bigbore single. Anything you use will fit your engine, but why not better than mineral?
Regards,
AnteK
