Customer Ratings & Reviews

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.

It’s great love it make my Hog run smooth!

My bike loves this stuff!

I have been Using AMSOIL fluids for several years. Could I find cheaper alternatives? Sure. But I have found Amsoil to be the best for my purposes. I don't take advantage of the extended OCI closing to change my oil around 3500 miles. I am running this in a FLTRXSE CVO 117 which in the Florida heat really tests oils. Highly recommended

Hands down, the best Harley oil ever. If you’ve ever hooked an oil pressure gauge to a Harley, you know how scary it can be at a hot idle. This oil is cheap insurance to know the engine won’t hurt itself at idle.

Picked up for a friend for his bike

Use this in my both my 93 and 01 Harleys... air cooled but bikes run a lot smoother and shift fantastic!! Great product!!!

I use this in all my Harley m8 oil changes. I have noticed a slight temperature drop in my oil heat. For now this is all I want in my scoot. Worth every penny in my book

Extremely great oil v-twin rides a lot cooler than previously used Mobil 1 Actually just purchased Amsoil transmission oil for my Harley which I will review at a later date

Great quality oil, the extended range also saves on oil changes

I am completely sold on this product. My bike runs excellent and no evidence of wear

Made engine quieter.

I use it in my Harley Davidson 110 CVO Twin cam, and in my 117 CVO Milwaukee 8. I have been running Amsoil for years and have never had any internal oil related issues. West coast summers get really hot out here where we are, and SoCal traffic is the worst, but with Amsoil in the oil tank you don't have to worry about what is going on inside your ride.
