Customer Ratings & Reviews

I live in a very hot environment and Amsoil is the only oil I use. I have never had an oil related issue in over 20 years. They also have the fastest shipping around, great job Amsoil.

I just recently bought a 2018 HD TriGlide. it had 5100 miles on it. All three systems needed (probably the first) oil changes. My Best friend has been using Amsoil for over 20 years, his bike runs great! First ride was to Coco Beach, FL and back 460 miles. Also, my shifter seemed quieter, after the oil change. Plus I actually researched and read many reviews. I'll be keeping an eye on everything for the next 5000 miles.

Awesome product Great price

smooth as silk

Blew rear head gasket due to water pump failure in middle of nowhere in Nevada had to run bike to dealership in flagstaff Arizona another 55 miles,this oil saved motor

I like the fact that I can use this in all holes. I noticed smoother shift and less noise. I couls say more but you need to try it for yourself.

Have used in all my Harleys and have never had an oil related issue.

Engine runs quieter and cooler when I run Amsoil. Can go 7500 to 10K when running Amsoil and not worry about the protection breaking down.

First time I've ever tried AMSOIL. But everything I have read sounds like a better oil than the Harley oil I have used for ever. Time will tell

I have been using 20W-50 Synthetic V-Twin Motorcycle Oil in my bikes for years and they have stood the test of time. I have had no engine issues what so ever. I am now using Amsoil in our SUV and totally satisfied with the results that Amsoil has provided. Great product.

Perfect oil for my Harleys. I’m going to switch to all my motor driven utilities. Recommend

Picked Amsoil based on their reputation and having been disappointed.

It really is liquid gold. Motorcycle needed an oil change so I decided to use the best and most recommended oil. Bike stated up and runs great with this oil. Definitely will keep using this.

The whole kid is very nice it's perfect that it all comes in one Box.

I did a 3 hole drain on my 2015 FLSTC and I can totally feel the difference compared to HD Synthetic brand. I strongly recommend this product. I choose to go with primary oil and tranny as opposed to engine oil and I can feel they work better.

This is the only oil I buy for my Harley. I ride it hard and it holds up even on the hottest of days. I live in Georgia and it gets hit in the summer. I highly recommend this oil if you ride a Harley

first oil change with this. So far so good.
