Customer Ratings & Reviews

I handle about 30-35 cases annually. It is my default lube when doing service. Customer asks by name. No doubt, THE best synthetic v-twin engine oil available anywhere

Have used this oil in my bike since 2013. It allows me to confidently change my fluids only once a year.

I use it in my 2019 Indian Roadmaster

very good product

I used this oil in my street glide and the engine seemed to run quieter.

Big motorcycle engines produce a LOT of heat, and Amsoil oil helps reduce that heat as well as standing up to the heat and provides engine protection in the most adverse conditions.

Works fine in our motorcycles.

First time using Amsoil in my Road King. Trying it in all three holes as suggested. So far so good. Finding neutral much easier now. I'll let you know what it looks and feels like after the next change.

I have used this oil in my Indian Roadmaster for all but the first 500 miles. After 30,000 trouble free miles, I wouldn't use anything else!

Using it on my 2014 Slim and 2008 X bones since after their first oil change Actually use AMSoil specific lubes in all three holes Bikes run cool, quiet and shift like butter. Neutral is always there and I never see metal deposit anywhere Both bikes have similar milage and just finally got around to opening the primary on them to check chain tension and was blown away that either bike didn't. No explanation for that, sorry. Best part while in there was seeng the nylon shoe on the chain tensioner was barely worn Hope to get another 40k mi out of them Love AMSoil lubes

The only oil for my Harley!

I operate my 1961 harley Davinsion duo glide also known as a pan head , I use it in the motor and four speed transmission ,having driven it eight thousand miles and only adding three quarts to top it up as the primary and secondary chains are lubricated by the engine oil and then allowed to drip out .I keep an eye on the quality of the oil by checking it with my lubricheck oil tester .

Best oil money can buy.

2009 Dyna Street Bob, 2010 Road King

I have over 149,000Km (92,500miles) on my 2015 H-D FLHXS and have always used Amsoil!

Works great I noticed a huge difference in how easy my bike shifts now and I noticed the engine does run a little cooler now, definitely gonna keep buying Amsoil now

i LOVE THE PRODUCT BUT PRICE IS STILL THE PROBLEM THANKS jJPK

After my trip to sturgis 5000 engine started to make noise

Have used this oil consistently on my 2003 Vstar with 50000 miles on it. Best you can do for a motor is use the best oil you can afford and change it regularly. Amsoil fits the bill. Thanks for a fine product

Great stuff!!!
