Customer Ratings & Reviews

I have used Amsoil for many years, the last bike I used it in I traded with almost 140K with no lubrication issues.

Great Oil at a Great Price for my 03 Bagger, it's better then any Oil out there and it's shipped right to your door

I use this oil in my motorcycle engine here in Las Vegas in the extreme heat; have over 90,000 miles on the 2009 Harley FLTRSE3.

Been using Amsoil in my 2009 Fat Bob since it was new.

Npthing but Amool will go in my motorcycles but Amsoil.Not only did it live up to what it claimed,The chattering and clicking in the Engine is gone the engine runs smoother and Im very satisfied with Amsoil oil for my motorcycle

I use this in my 2009 screaming eagle springer . Been using it for 7 years works great seems to keep engine cool

all 5 Harleys an 3 ktm's rely on amsoil.everything is running strong.

This stuff is so good, Was on trip with my brother thru CA AZ To Utah on my Indian Air Cooled .The Temp was anywhere between 107-118. Never had a heating problem and never had to add oil. This oil is the best hands down.

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.
