Customer Ratings & Reviews

I used Amsoil 20W50 V-Twin motorcycle oil for over 80,000 miles in my 2005 Harley and it was still running strong at 120,000 when I traded up to a 2016 Harley. I specified Amsoil at the 500 mile service and have rolled up 13,000 trouble free miles already. Looking forward to another 100,000.

After breakin on my new rebuild stroker evo, I added this 20W-50 synthetic V-twin oil. Then set out for 5,380 mile road trip, 2 up in mostly 90-100+ F heat. Total oil added was less than 2 oz! No heating issues! Very impressed with this product.

I use AMSOIL products in the Engine, Transmission and Primary case of all the Harley-Davidson motorcycles I've owned since I started riding after a 40 year hiatus in 2012. I have also used AMSOIL in all of my air cooled Volkswagen powered vehicles for decades. You can't beat it's quality. The fact AMSOIL sells application specific lubricants that really ARE superior to "universal" lubricants is a HUGE plus too.

Improved the performance and gas mileage on my motorcycle.

I use this in two cruisers and one sport bike, No complaints ,good service ,good price.

Have used this oil in my Harley-Davidson motorcycles for 15 years, I believe it to be the best for air cooled big bore engines.

I only use amsol in my Harley's and amsoil in my boat I gained rpm on top end it proved its benefits

Only the best for my customers, this oil lowers the operating temperature of big twins by a few degrees compared to the HD product and is the only oil I stock.

Bike has almost 200,000 miles and runs cooler than any other oil I've tried.

I am a motorcycle shop and use Amsoil exclusively in mine and my customer's motorcycles.

This is the only oil I have ever used in my Harleys and I plan to keep it that way. I've had zero issues with my bikes and they my oil temps never get out of control no matter how hot it gets in the summer.

I use the 20W-40 in my Indian Motorcycle. Always preferred Amsoil with all of my bikes, previous and current. Good pricing, good product.

Awesome oil and very quick shipping time all my Harley's have Amsoil in them and NASCAR late models do as well great stuff

Best oil on the market ! Runs cooler and lasts longer. I've run both coasts from Colorado, 3 different Harley's. Run amsoil in all my vehicles

This grade of oil is the only one Indian Motorcycles allows in their machines. Amsoil is the only major producer of this oil. Also the durability and long lasting quality of this product is what makes me happy.

I use this in my 2004 ultra classic it seem to work real well in the hot weather. The only thing I've been disappointed in was the last price increase i may have to look at other options.

I have a Victory Cross Country Tour. Ams oil is the only oil that gives me quiet starts and consistent clutch feel. Its been the only oil that has allowed me to go 5000 miles between changes. You can really tell the difference with Ams Oil....
