I love this oil. It keeps my bike running smoothly and at slightly lower temperatures than other synthetic oil. Can’t beat it.

Best Engine Oil on the Market

Amsoil Synthetic and filter combo is the best. I change fluids religiously, every 5k miles, and I ride hard, in all weather conditions. The viscosity is still good at 5k. Switching from the OEM to Amsoil, the engine immediately ran cooler, smoother and with less rocker noise (which is inherent to V-twins). Amsoil synthetic is truly worth the purchase and use.
Have used this oil for over 30,000 miles in my present bike an 02' Police Electraglide and over 40,000 miles in my 05' Electraglide with very good results. I would recommend this to anyone who would like long engine life.
Bottom Line
Yes, I would recommend this to a friend.
