Customer Ratings & Reviews

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....

Running cooler??

Some of the best oil I've ever run. Great for the Harley or the dirt bikes.

I use it in my 2016 Harley Davidson it is best oil on the market Hands Down!

Great product super fast delivery

Excellent oil. Better than all of the oils I have ever used.

Pro Atv Desert racer been running 20-50 now for the last 8yrs changing the oil after 2 races which average a couple hundred miles each and a few hrs of brutal punishment and harsh Arizona desert summer temps I replace the cylinder and piston at the end of Every season after over a 1000 miles and over a hundred total hrs in a season the piston and cylinder look as if they did when I installed them, the last 8yrs I have not had any engine failures of any sort and it's because of AMSOIL synthetics. I've seen so many guys I race with blow there engines time and time again during the season and they continue using their own preferences of oils and still have issues. I have so much confidence in AMSOIL when going racing that engine failures don't even cross my mind.........thank you AMSOIL for your continued sponsorship support and your hard work put in by your R&D department.......It's paying off....."!!!!!

Great oil

I used this in my BMW motorcycle and have to say, it is a very good oil from what I can tell. 4K miles since the oil change and it still shifts smoothly. That has never happened before I used 20W-50. Overall, the bike runs very well on this stuff. Will be buying it again

Used this for years great product
