Customer Ratings & Reviews

Use in all three holes on my Harley. Smooth shifting and no issues with heat at all bike runs constant. Will always use this oil!

I have been using this oil for over 20 years on all my Harleys. Excellent lubrication for motor, transmission, & primary. It is my go to oil for anyone who asks.

This oil lives up to it's well earned reputation as the best oil on the market. I consider my Harley to be an expensive investment and will only ever use the best products available. For lubrication that is Amsoil

Works great. Bike runs a couple degrees cooler and the shifts feel crisper, much easier to find neutral when it’s hot on a bike that is notoriously hard to find neutral

Great products. Long change intervals and superior protection from wear and heat.

Runs cooler

I've used Amsoil in all my bikes since 2008. I send every other oil change to Blackstone for analysis and it always comes be great. Amsoil is all I use in all 3 holes.

Oil works excellent in my bike

Will always use

The engine oil for a H.D. V - Rod Screaming Eagle.

This oil is a very good product for the money. I don’t have access to a laboratory to actually test all the claims that all the petroleum companies, profess however, my Road Kings seem to run somewhat cooler and use less oil with AMSOIL. I have used multiple oils and I’ve settled on this one for my rides.

It's Amsoil..what else need I say?

Quickservice noticed a difference since I switched to amsoil

Amaoil is the original synthetic and the leader in quality. I use nothing but Amsoil in all my vehicles from my truck to my ATV.

Perfect for Harley

Been using this product for years great oil, they offer the correct oil for the three different holes on my bike, not the one oil fits all crap!

My FLHTCU now has 72000 miles on it. From the first 600-mile oil change, this is the only oil I have used. My oil is changed every 5000 miles. Every time I change the oil, I submit a sample for analysis. Each time, it comes back clean. At my last full service, I did a cylinder leak-down test, and the results returned 5%. Outstanding for an air-cooled engine at 70000 miles! Best oil on the market.

I have been using Amsoil in my Motorcycles for over 20 years. I service many bikes in my shop over the course of a year & always suggest Amsoil. Have never experienced any issues. It provides the needed protection for all temperature ranges. I just returned from a 6200 mile motorcycle trip with absolutely no issues. I also like the extended mileage between oil changes. I typically go 7500 miles between changes but accidently went 10,000 miles one time and the oil looked normal when I did change it.

I only use Amsoil products in my Harleys, nothing else.

Definitely an excellent choice for maintaining engine performance and endurance.
