I've used this 20W50 in several air cooled Engines with great results. In Evo and Twincam Harleys it can be used in the primary and tranny as well. One oil for everything, easy. Been using it in a Yamaha Road Star last season (10'000km). No issues, hot or cold. Highly recommend this oil
this oil is great stuff, I use it in my vintage bikes, a 68 BSA and a 70 triumph Bonneville. It works good in these bikes.
Bottom Line
Yes, I would recommend this to a friend.

Have used many synthetic oils. Amsoil is top notch. Far quieter than other oils as far as engine noise. Amsoil Tranny fluid outshines the competition with smoother shifting and ease of finding neutral. If you ride a Harley, you know what I'm talking about.
This oil makes the bike run smoother and quieter. I like that I can use it in the Engine, Trans, and the Primary. I use Amsoil in all my vehicles. Nice to change oil and filter once a season and still get great protection.
I bought the 20W40 for use in my Victory Cross Country. The top end is noticibly quieter. The oil change is good for a year, or 10,000 miles. I'm happy!
Becoming a preferred member has made this top grade oil not only affordable, but because of its longevity it is a much better value than other synthetic brands!
I have a motorcycle repair shop and I am switching to Amsoil. Superior product and better priced. I won't use anything else in my Harley-Davidson. Another advantage is I can deal directly with Amsoil, can't do that with other manufacturers. Overall a fantastic product and company! Order online and it comes to your door.
