Customer Ratings & Reviews

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.

I always use AMSOIL in my bikes. It has proven to be the best whether crankcase transfer or transmission. Smoother performance and cooler running. It is said all oils are the same, and I used to believe that.. but not since using AMSOIL. Just the best.

AMSOIL V-Twin is the only oil I use in my Harley. I highly recommend it.

This oil change is great and cheaper than Harley!! Couldn't believe the difference it made in performance!!! 100% recommend!!

Excellent kit for a 2022 HD Ultra LMTD, comes with gloves, funnel, o-ring, filter and the best oil on the market. Well worth the money!

Awesome quick service tried product for first time and I’ll never go back to what was using

I change the fluid in all 3 holes in both of my 2021 Road Kings every 5k miles. One has 35k and the other has 20k, both run like brand new still. I wouldn’t use anything else in either of them. Trans takes 28oz, diff takes 30oz, and engine gets 4.5qts. Torque all the drain plugs to 18ftlbs, and you are good to go.

Effortlessly pull easier very smooth
