Customer Ratings & Reviews

I have used this in any of my Harleys over the last 8 years. The bike seems to run quieter and generates less heat. Don't use it during the break-in period, or the rings will never seat properly. Use Harley's oil (360) for the first 5000 miles, then switch over.

Good stuff. Would recommend to anyone. Use it in my '13 ultra classic. Change out between 5 n 7k miles. All three holes.

Am using Amsoil in my third Harley, have used it since the first oil change. Absolutely no problems, ever!

Use Amsoil products in the 3 compartments - crankcase, transmission & primary.

LOVE THE PRODUCT USED FOR 15+ YEARS

It don't get any better than this stuff, I was introduced to Amsoil 14 years ago, I used to use Mobil 1. This stuff is the best, and don't forget the tranny and primary oils too

Love it I use it in all my equipment

I trust the oil after I saw the video

Last year I used Yamaha lube in my royal star motorcycle first time not using Amsoil. Was not happy with the Yamaha product, the clutch on tbe bike was slipping thought about replacing it. This year I put Amsoil back in and no clutch problems. I have complete trust in Amsoil for engine longevity.

I have used this product in my engine , transmission and primary I've used it from I bought the bike brand new until I sold it at 86,000 miles never had a problem not from day one . Engine ran quiet smooth and cool great performance I would recommend this product to anyone .

Great for my 6 year old Harley.

I put Amsoil in every vehicle I own. Hands down the BEST.

Great product i use amzoil exclusively for all purposes in all of my vehicles and machines .

The best oil I have ever ran in my Harley. It runs cooler, the engine is cleaner and it has superior protection.

Run this in my 2016 Indian Springfield and it noticeably quite the engine

Works and last better than other oils I have used

I will only use 20/50 Amsoil in my Harley. The engine is air cooled and depends on the oil to not break down under extreme heat conditions. I also run it in the primary case to lube that area.

Great products and pricing , it's all I use :)

I use Amsoil exclusively in my Indian Chieftain and wouldn't use any other oil product. Period. Hot weather, cold weather and everything in between I know my engine is being protected and kept clean.

big difference fo the oil from Harley . it's quite run's cooler in the motor. shifts better in the Tran's very happy with it.
