Customer Ratings & Reviews

Very easy search engine and prompt delivery. Would definitely recommend Amsoil products to anyone.

Been using Amoil 20/40 in 4 victory motorcycles many years, Very happy! Mileage runs from 10,000 to 88,ooo zero problem.

This oil is great! I have been using it in all my motorcycles for the last 10 years. Engine runs quieter & transmission shifts smoother. I recommend to all my riding friends.

Excellent product by far the best oil made for v-twin motorcycles

This gets used by many legend cars racing around this area.

I started using Amsoil several years ago in my bikes and have had zero oil related issues with any of them. In my older Road King, I think it actually quieted down the lifters a little especially when it was hot out and sitting in traffic. I use it in all 3 holes and will continue to do so.

Best motorcycle oil in the world

Made motor run smother and quiter thanks

Used for the first time in my 2017 Street glide. So far so good. Came highly recommended from other riders.

I only use Amsoil in my motorcycle, it's the best:)

After using other products recommended for my Harley Davidson for years, I began to wonder if I was taking the best care of my bike that I could. I started looking at all the lubricants available, and what people were using, and why. First of all, I don't like having to have a few ounces of one lubricant in the primary, a few more of something else in the transmission, and then something else for the engine oil. Next, I read as many technical reports as I could find comparing different products, and I watched a number of videos displaying the wear results of different products. Then I compared the price for different products. I came to the conclusion that Amsoil would be the best choice, in every regard, for me to use in my bike going forward: 1- Same lubricant in all three holes. 2 - Best wear protection available. 3 - Priced competitively. Those facts are in addition to me being able to receive a substantial discount by paying a small subscription fee. And I can get online, place my order, and have it here in a few days. All that to say, Amsoil...you're probably stuck with me as a customer for life!

I've tried several different brands of synthetic motorcycle oil. Amsoil 20w 50 is the best so far. Particularly, a smoother shifting trans and quieter cam chains in the engine of my Harley V Rod VRSCA. Good product. I'm a believer.

I have had food luck with this oil. Even in cold weather I always have good oil pressure.

love this oil

When it comes fluid Lubrication, your not going to do better then amsoil. Meets or exceeds all manufacturers recommended standards. I’ve used amsoil for over 20 years and never had an engine failure. I also use amsoil in my tranny, and primary when out problems. You can count on my review to be the truth and you can count on amsoil to protect your engine.

I was introduced to Amzoil about 2005 when I purchased a Harley Electra Glide CVO, I ran that bike 54,000 miles. I bought a Harley Road Glide new in 2010, it has 74,000+ miles now, still runs like new. When I belonged to a club a few years ago three quarters of my members (about 10-12, had me doing oil changes in my garage, because I had a pneumatic lift, all those bikes ran Amzoil in the crank case, transmission, and primary case. Never had any problems in any of them. I would highly recommend the product.
