Customer Ratings & Reviews

I've been using this in my Indian Motorcycles for the last couple of years and I think the engine noise is quieter and the engine runs a bit cooler. May be all in my head but at least I know I'm doing all I can for the longevity of my engine.

Great quality product but customer service sucks sending free offers 1 day after my order not cool

Buy online no trip to the shop ,delivered to my door hassle free amsoil is a very good oil this is the one I like for my Harleys engine.

Great product . Quick shipping . Very satisfied . Would recommend .

Amsoil always. I never use anything else. Great Product

Superior product

I have an 2001 Harley softtail and I've run this oil for over 20 years. There has been times where I have pushed the time between oil changes due to life. In 2004 I had a gear cam and a big bore kit installed. A long story short riding hard at times and pushing the bike even parades which is hard due to over heating I have never had ANY problems. I have all the confidence in the world in this product and would recommend it to everyone out there.

Great value great service. What else can one ask for?

I won’t put anything else in my motorcycle

Good quality oil and fast shipping

Oil helped out seems to be a very good compromise for my engine solution

Best oil in my opinion. Lowers engine temp also.

Web site is easy to navigate. Prices are right Order was filled to perfection Shipping was quick

I’ve been using Amsoil in my Harleys for about 15 years. I use the 20W-50 synthetic V Twin in Engine, Primary and Transmission. From the first time I used it the bike was much smoother and ran cooler. There is definitely a difference. Won’t use anything else in them.

Decent oil for the price. Quick delivery.

Its the only lube I run in my Harley!!

Quietened my noisey vstar right down…. I won’t run anything else!

I recently did the valve maintenance on my son’s Kawasaki 1400, which he has been using Amsoil in with a K&N filter. I have been working on engines of all sizes and fuels for over 40 years. The engine on the Kawasaki was super clean and had no wear issues on the cam journals. The internal engine parts were clean and slick but not oily. I definitely contribute the condition of the engine to Amsoil full synthetic.

I have used amsoil in my vehicle s for years I feel the quality and performance is worth the extra cost, pretty cheap insurance. My roadmaster runs a little hot and I ride in some hot area's ,I have my oil tested every oil change so far viscosity and mineral levels have been in the normal operating fields. Use it and feel safe

I have used this oil exclusively in both my 110 Twin Cam and 117 M8 engines, I've put many miles on both of them in the California heat and cold. I have personally never had any oil related issues. The price of Amsoil in my experience is cheap insurance and gives you worry free protection mile after mile.
