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.

Might be all the hype but I truely believe the bike runs smoother and cooler. Well worth the money

Use in my Harley

I first tried this oil in a '16 cvo street glide stage 4 . It really help quite the lifters and run cooler.what really impressed me was the Amsoil test where they ran a sportster 1200 to 600 degrees f. Until it melted the oil drain pan. Oil test proved no metal or oil breakdown and that was enough for me.

Although the manufacturer recommends synthetic blend oil for my bike, I swear by Amsoil. My engine and transmission run off the same fluids so I want no malfunctions. Amsoil keeps things running smoothly with no slippage what so ever!!

Always performs at a superior level.
