Customer Ratings & Reviews

use it in my Harley,1998 wide glide.runs MUCH COOLER using it.

I've tried 2-3 different synthetics as well as heavy duty diesel oil in my 2011 FLHTK Electra Glide. This product makes my scoot run much cooler (rear cylinder get so hot I'd glance down to see if my pants were on fire- not any more). When you add in the fact of extended service periods, that, my friend, is value.

I'm impressed how amsoil has increased my fuel mileage in my Harley. It not only increased mileage but also has reduced engine temperature by more than 20 degrees. I have a oil temp gauge on my bike and for years I used other well known synthetic oils. No other oils reduced the temperature which will result in performance and fuel economy.

On the Victory Forums this is always a huge debate. What oil do you use? I went with one I trusted. Bike runs smooth and cool.

Only oil I have used in my Road King since I bought it new. I passed 50k miles last year and have never had any issues with oil loss between oil changes or oil leaks. I recommend this product to everyone I know that rides a V-Twin.

I hate surveys, but I read "The Circle" and realize they are very important to you. If I didn't love the product I wouldn't keep buying it.

I use this engine oil in my 2016 Harley Davidson. It does a great job on long distance runs keeping the engine cooler and smooth running. I use no other oils in this engine.

After switching to amsoil most of my friends have switched as well .

Amsoil MC oil is the only oil I can completely trust to protect my Indian motorcycle while it's running but to protect it from rust while it sits during the winter months.

I use Amsoil in all my motorcycles. 20W50 in engine, Primary fluid and Transmission oil. From all evidence I have, this is the top synthetic oil on the market today. I want nothing but the best for my bikes and in my opinion this is it.

I put this stuff in a 2010 Ultra Limited that I bought with 32K on it. 200 miles later heretofore unheard noises started, am in the process of repairs. So far the front exhaust lifter is trash and it took out the cam with it, don't know the full extent of damage yet. So you tell me "Which came first, the chicken or the egg?

Have used this for every oil change since the dealership 500 mile break in that they paid for. Cycle has shifted better since the change to amsoil.

I use this oil in my Harley Davidson. First time I used it in my 2013 Street Glide FLHX 103ci motor just got it back from putting a stage 4 Racing Kit in it and put almost 46.000 miles on it in 3 years and used the 60 weight full synthetic in the motor transmission and primary and changed it every 5000 miles witch didn't take long. It tuned on the dyno at 112 HP and 121 pounds of torque. After spending all that money on the engine I won't it a oil to keep it new inside with no ware on the parts and that's what I got from AMSOIL. Now I own a 2017 Street Glide 107ci and had some work done on that motor also and it is a BAD. It pulls the wheal 1st 2nd and 3rd gear and don't Know when to stop running. After the break in oil was ready to be changed I also had the motor work done on it also and had them to put the best in it. So Y not use the best oil so I had them put 20w 50 in all of Motor Transmission and Primary. Now I just turned it over to 4000 miles on the engine now after are last trip and I don't baby it I run it on the Interstate 80 85 90 depends on how the traffic is flowing and I will fall in and roll with it with no worries about my engine because I know its being protected and staying cooler and no ware and tare. Also the shifting is quitter and smoother and the Transmission like the Engine smooth and no ware and tare. Now I'm fixing to order me some AMSOIL because it is getting close to my oil change and don't forget about there Oil Filter It does the Job that no other filter can and that is all the bad stuff don't get through keep that oil Pure.

With all the lubricants out there, and all the claims how do you know you're getting the best protection. I use Amsoil then I know I'm getting the best protection.

I started using AMZOI: products a few years ago, signed up as a preferred customer and I am a true believer in their products My wife and I each ride Harley's and feel the AMZOIL full synesthetic lubricants are the best on the market. There are two things that will cause an engine to fail, heat and friction. Using AMZOIL is one of the best ways to prevent friction and protection for heat.

Keeps my bikes engine, trans,primary running smooth and cooler

After my initial break in of my bike, amsoil was introduced . Here in central Florida it gets really hot in stop and go traffic. In conjunction with my oil cooler and amsoil 20w-50 , I have piece of mind that my bike is well protected. Thanks amsoil.

I have been an Amsoil Preferred Customer for many years ,I use Amsoil for all of my vehicles and equipment. I have never had a single oil related failure, or any failure for that matter. I just did my first oil change on my 2017 Street Glide and noticed a difference right away in the running and smoothness of the engine. My only wish is that Amsoil will put together a "Kit" for the 2017 Harley Davidson Milwaukee 8 owners. We use 4.5 quarts of crankcase oil instead of 4 quarts. Help us oil Amsoil !

What I noticed immediately was how much cooler the motor runs. I have used this product since my bike was new and won't consider using anything else.

I use this in both my wife's and my Harley Davidson motorcycles.Very good oil
