Customer Ratings & Reviews

I use this in all 7 of my bikes.

I recently joined the AMSOIL family after talking with several other people over the years about their experiences. I am extremely satisfied with the product and immediately noticed smoother shifting and idle. I was however disappointed in the design of the one gallon jugs. Most manufacturers have realized the benefit of a easy pour design and have incorporated it into their large capacity containers. That is one feature that I miss...

First time using this oil dropped my bikes oil temp 10° Highly recommended.

Goes in my Twin Cam 96 Harley. I've been putting it in all three holes. Works well.

Great for my motorcycle

I have been using Amsoil 20/50 synthetic engine oil in all my bikes since 2003 and I prefer to use no other product than this. This oil Meets all my driving needs during the winter and the hot summers I have never found this out to fail. I am 100% satisfied and will continue using Amsoil 20/50 synthetic. Also whenever I order from Amsoil my order comes within a few days.

I use this in my Harley and it seems to do a good job.

Great product have used this product for 10years. Will continue to do so.

Amsoll is the life blood of my Harley. Air & Oil are the 2 cooling agents that keep a Harley running. AMSoil does it better, the bike runs quieter, and I have confidence that my girl will keep on going even in these HOT Florida days.

This is the best oil I have found around. The price is comparable to other brands but they don't do the same job. My engine runs cooler and for a Harley that is air cooled that's important and for my bike being 27 years old it needs the best.

Very clean oil great for all temps of riding

Best in the business.

Amsoil is the best

Hands down best oil. My bikes run cooler and even going longer between changes, it doesn't seem to break down.

Great products

It's got what it takes for heat and clang reduction.

The 20w-50 synthetic V-twin motorcycle oil makes the shifting of the transmission smoother than stock oil, and shifting into neutral is the best ever with Amsoil. Also engine oil pressure when hot maintains constant oil pressure

After reading many oil surveys, Amsoil was the most popular among Harley owners old and new. I have used Amsoil in my cars and trucks for a while now, so it was a natural choice. The difference on start up is instantly noticeable with a big reduction in mechanical clatter.

I have used Amsoil VTwin for 10years. I have a 2012 ElctraGlide with 165k miles and have never been into the engine. I reccomend Ansoil to everyone I speak to about oil.

Use Amsoil in everything I own except airplane. Both Harley's use this and associated tranny and primary.
