When one isn’t enough. Go big or go home

My 04 Harley Davidson FXDI Superglide runs great with your oil.I can hear and feel the difference. I will definitely continue using Amsoil products.

Since using you oil on my 103 I noticed when the bike got hot it still had oil pressure . I used Harley synthetic oil from purchase oil my 2013 when it got hot I had 0 oil pressure obviously your product is better

I use this oil in all three Harleys and works great, bikes run cooler and shift smoother. Very happy with this oil.

I have been using this oil for decades. I will continue to use it for decades to come.

Great product, but all the adds say free shipping over but I did not get that I was charged shipping

Excellent oil, Excellent for my Harley very good.

Engine feel less friction

Amsoil in my engines make me feel good….3000 miles since last change and oil looked new

I've been running this oil in my '21 Indian Roadmaster since new. Now at 42k miles and no problems at all. I can buy this oil, a high quality WIX oil filter, and get the copper crush washers in bulk cheaper than I can buy the semi-synthetic Indian oil kits for. Much better quality for the same cost.

Just bought a used Harley that the previous owner used Harley Syn oil in. I immediately order Amsoil Syn motorcycle oil. Boy did it make a difference. Can’t wait to change the primary and transmission to Amsoil products!

I have a 2006 Road King. I switched over from Amsoil 20w-50 to the straight SAE 60w because of the Heat here in Florida. My bike runs cooler than before, and I recommend this product very highly

Great product great service.............

Love the fast delivery. This is excellent oil and weight for hotter climates . If your coming from here ( Prince George) and heading for say Kelowna on extended stay , it is a perfect oil to use and protect your engine .

I have been an Amsoil user on my vehicles for over 20 years, when it comes to my two motorcycles, it is the ONLY oil that has ever been used on them, my older bike has over 80k miles and still runs great, my newer bike has over 45k and still runs great. Quality and price wise in my opinion Amsoil is #1!!

Use in all three holes on my Harley. Smooth shifting and no issues with heat at all bike runs constant. Will always use this oil!

I have been using this oil for over 20 years on all my Harleys. Excellent lubrication for motor, transmission, & primary. It is my go to oil for anyone who asks.

This oil lives up to it's well earned reputation as the best oil on the market. I consider my Harley to be an expensive investment and will only ever use the best products available. For lubrication that is Amsoil

Works great. Bike runs a couple degrees cooler and the shifts feel crisper, much easier to find neutral when it’s hot on a bike that is notoriously hard to find neutral

Great products. Long change intervals and superior protection from wear and heat.
