I've got a 2012 and after reading the posts here, I decided I'd try to get something more locally obtainable w/o ordering it. So, here goes. I'm using Valvoline 20-50 motorcycle (clutch compatible) in the engine, primary and 75-90 syn blend in the trans. My oil all gets changed in the spring of the year and usually only has 3-5000 miles on it. Just my .02. Happy Trails.
