Customer Ratings & Reviews

The bike runs nice… it’s real nice.

I have 3 Harleys it's the only thing I use

This oil eliminates that pesky valve ticking at higher RPM, Great stuff

Have used amsoil in every thing I own even my late model stock car

I have been using this oil in my harleys since 1994 and have never had an issue with regards to oiling on my bikes. I wouldn't consider using a different oil.

Always handy to get this kit for my 2008 Softail Heritage. Everything that's needed in one package.

Great oil, kidda pricey though

First time using this full synthetic oil along with the AMSOIL oil filter for my 2019 Indian Chieftain and right away I felt the improvement on my bike. Shifting feels smoother and engine runs better. I will definitely use this again on my next oil change.

Great product my bike is running smooth

Great product at a reasonable price. Great service. Delivered right to my door the next day. It is worth buying a loyal customer membership as you save more than the cost of membership on their products.

Amsoil in all 3 holes every time on the M8

Found Amsoil on-line to be cheaper than local retailers. First purchase was 12 quarts of Amsoil V-Twin SAE 20W-40 synthetic oil for my Victory. Came with a free package of rags and a free funnel. Shipping was free and arrived within time stated on order. Very satisfied.

Always what I order always on time

Bike runs cooler and quieter

I have been using this oil since I bought my Ultra Classic, and when I changed the oil at 5,000 miles, it was still reasonably clean.

Great oil but I did not receive my free funnel and shop rags.

Good product, well packaged, very fast delivery

I change my engine oil and primary and transmission every 3000 miles using amsoil product with excellent results..! Thank you..

Helps keep a modified M8 cool in summer heat!

Received product quickly. Arrived as described and ordered. Thank you.
