Customer Ratings & Reviews

Good oil. Used it on my motors for years. Have a 07 Harley dresser. 98,000 miles. Used in primary and tranny.

Have used it for about 10 years in multiple Harley Davidsons that I have owned, as well as put it in other's bikes that I have serviced. Not about to change what works.

I use Amsoil in all my equipment, tractor... compressor... car....truck.....lawnmower...bike.

Great product. Use in all my bikes

I purchase this product for friends of fine that use it in their Harley Davidson motorcycle. They tried other products but Amsoil is the only product that works to keep the engine cool, smooth and protect against all elements.

I changed out my out Harley Davison engine oil with Amsoil. Immediately the engine ran quieter. The feels like it runs a little cooler as well.

Great product...AMSOIL I use it in everything... Trucks, Motorcycle... Only oil I use, if U value your vehicles, Use it...

As always really like the Amsoil, I have changed all my vehicles over to it along with my motorcycle and will be switching my tractor over on the next change.

I've used this product in my bikes for many years. No second choice. I carry a quart with each vehicle for top ups if needed. Used in both 95 and 99 Evos and 04 and 10 Twin Cams.

Best synthetic oil for motorcycles

I really appreciated the quality and consistency of the Amsoil products! I use nothing but Amsoil fluids and filters in both of my Harley Davidson motorcycles and continue to be impressed on how well the products perform!

My 2017 V Rod Muscle used oil every time i used Harley Davidson s3. Now i switched to amsoil it doesn't use any!

Have been using AMSOIL in my vehicles for about 10 years now. I am very happy with the performance. I have used the 20W-50 in my BMW R1200RT since it was new in 2009 and it has worked great.

I love this stuff, it keeps my bike running in top shape! I put 6000 miles on an oil change this past summer and it still looks great, I could probably run it half of next season too.

ok

I use Amsoil for all my vehicles. I have nothing but good thinks to say about their products. A true synthetic unlike others brand who are blends of motor oils.

Makes your motor perform as intended and offers the best protection you could hope for

Love the product you make and will continue to use it for every thing I own

Great online service.

I have switched all my rigs to Amsoil. Both my trucks a Dodge 3500 with a Cummins Turbo Diesel and a Nissan Frontier with a 4L V6 and my Harley Davidson.
