Keeps my 2017 Harley Davidson Ultra running cool in this hot Florida weather. I have used it for many years and on many different motorcycles. Great product.

Started using Amsoil motorcycle oil about 8 years ago and just think it's the best oil made today, my Harley's love it. I used to use a different oil and think it still works, but i know this oil does the job better.
