Customer Ratings & Reviews

Great product I will use it again.

Works great, I run my bike hard for long periods of time between oil changes AMSOIL keeps my 2016 Harley Roadking preforming cool and efficient with improved gas mileage. Highly recommended this product. They also have outstanding shipping services orders arrive in most cases in 3 days. 😁

Although not recommended by any oil manufacturers in mixing weight in the engine oil, I am running half SAE60 in routine oil change. HD air-cool engines have larger tolerances in the internal working mechanism, this thicker oil works well for me.

Wouldn’t use any other product. Keeps engine running cooler.

This trans fluid is amazing within a short distance I could feel the deference in the way it shifted and finding neutral was much easier and just got better with time.

Its the 3rd case ive bought and am happy with its results .

I purchased my first Harley in 2008 and have used nothing but V-Twin since and Ea filters since. My bikes have never engine transmission problems or run too hot.

Switched from Victory (Polaris) branded oil to this Amsoil product 3 years ago. The bike runs a little cooler and oil seems fine throughout riding season. Haven't had any issues with shifting either as the gear box on these bike share crankcase oil.

Great oil! Great company! Oil I can trust!

Great trans fluid. I wish it had some color to it because it stays so clear it's hard to read on the dipstick

This oil is amazing, I bought a 2016 street glide, the thing had regular Harley oil in it when I bought it, changed out everything, the engine, the transmission, and the primary, it starts up easier, I can get it into neutral a lot easier, it’s a different bike all together now, guys try this oil in your bike, you won’t be disappointed

This is the first time I’ve used Amsoil. This has been a low mileage season but so far my ‘02 110 stroker motor is running about 30 degrees cooler and the valve train is noticeably quieter!!

Awesome product so far! Quieter tappets in my Sportster for sure!!

Switched to absolutely versus Indian oil . Definitely made a difference. Not as much chinging in the motor .

I’ve been an Amsoil customer for quite a few years now simply because they make a superior product. With the independent testing and the extended oil change intervals, it’s a win win.
