Anyone using Amsoil 20 50 in their bikes? I'm thinking about using it in my new 2015 CVO. The closest real (w/parts dept) harley dealer is 130 miles away, I can get Amsoil locally. The local harley tee shirt shop says two weeks before they have harley 20 50 syn. The bike is new and ready for the 1000 mile fluid change. I was thinking using the amsoil in motor, primary and tranny. thanks for the help.
