Customer Ratings & Reviews

Have been using this in my Fat boy since I bought it. Runs cooler and smoother than everyone's I've talked too, Great product!

Great oil but the chrome oil filter did not fit and I had to purchase one that was not Amsoil

I use Amsoil products in my diesel truck, my car, motorcycles, love all of it.

Have used AmsOil the past 35+ years. Why use any else when I can use the best! I have complete and total confidence in the product. High temps, low temps.....AmsOil keeps me on the road!!!

I use this on my Harley! The best thing about this is Amsoil shipped this to me in Japan and I had it in hand within 10 days of ordering . QUICK- FAST and RELIABLE !!

Pretty happy with it. It seems to be quiter then what I was using. The only thing that matters is I will use it again.

This is the best oil for my Victory. I ride almost every day, everywhere. I need an oil I can trust to take good care of my bike.

I started using Amsoil 20/50 Motorcycle Oil along with Severe Gear 75-140 Gear Oil for the transmission,when I had the 1000 mile break in service on my 09' Harley FLHRC. Now the bike is still running like a clock at 102758 miles on her. I recommend this product to everyone I know.

I use Amsoil in all of my cars and motorcycles. I own a 2009 Ford Fusion with 80,000 miles on it. I have a 2005 Nissan Maxima with 75,000 miles on it. I have a 2000 Nissan Frontier with 88,000 miles on it. Amsoil is used in all three and I know without any doubt my three 4 wheeled vehicles will last many more thousand miles. I own a 2009 Harley Davidson Ultra Classic with 73,000 miles and a 2009 Street Glide with 55,000 miles. And just like my cars and truck I know with Amsoil they have many more miles left to go. Thanks to Amsoil!!!

I have all my customers running it in there bikes.easier to find it locally when im out.

Been using it for about 10 years on my Harley love it.

I use this oil for transmission,primary and engine.

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.
