I have been using Amsoil in my current Harley Trike, and also using Amsoil in my three previous Harley "Big Engine", cross-country, Cruisers. I started using Amsoil in my Harley in 2009, during my first, 6-day, round-trip, cross-country ride from Pa. to California, when I was riding multiple, consecutive, 1,1000 mile and 1,200 miles days during my first Cross-country ride. I trust Amsoil to keep its Viscosity in the extreme heat developed by the Air-Cooled Engines, while riding hours on end, in the Heat of the Deserts that I have ridden through during my multiple cross-country rides. I am not denigrating other name-brand Synthetic Oil, I am just trusting my Harley Engine, Transmission, and Primary Case Gears to Amsoil.
