Customer Ratings & Reviews

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.

I cannot say enough good things about Amsoil, just buy/use it. It is the only oil I use in all my vehicles/equipment.

Best oils, best customer svc.

Best motorcycle oils I have ever used. We will continue to use over and over for our Harleys

Seems great. Last year I used Redline. Wanted to change this time. Looking to compare them. The oil, primary, and the tranny. Will find out soon; first long ride is Rolling Thunder over Memorial Day.

This product is the best in the USA. The heat ratio for Harley Davidson to be controlled in the State Of Florida is very important and demanding. Well this synthetic V Twin oil 20 w 50 out does in performance and heat and engine wear. I tested just about every oil that is produce that withstands all odds. The oil I tested, was lucas, Mobile 1, Harley Davidson Oil. Well Amsoil out ranks, out performs all of them

My Harley love it, This time I used the tranny oil and the final drive oil !! It awesome !

I use AMSOIL in everything I own, fast service, saves money and motors last longer. Best oil out there!!

Friends we teach civilian and our Military riders the skills and techniques used by our Nations Top Motor Officers. And I can tell ya it gets plenty hot in the summer heat with surface temperatures on range soaring over a 100. Our air cooled motorcycles, wet clutches and brakes don't stand a chance. That's why we never use anything but Amsoil products everywhere! They're tried, tested and proven. And that's all we recommend them to our students too! If you what to reduce operating temperatures and even thrive in the toughest conditions. You need Amsoil. :-)
