Amsoil is the only oil, transmission, and primary fluid I use in my Harley. My high mileage bike deserves the very best protection and Amsoil has done an outstanding job for years. My internal parts show almost no signs of wear after using it for the last 13 years.
2022 Harley purchased new had a great deal of problems shifting to neutral. After changing the primary and transmission fluid to Amsoil full synthetic, the shifting was probably 85% better! Highly recommend!
Bottom Line
Yes, I would recommend this to a friend.

I change my fluids every 5,000 miles and been using the Primary fluid ever since it came out and I have never had any problems.
I will use AMSOIL in every Harley that I will ever own.
Bottom Line
Yes, I would recommend this to a friend.
