Customer Ratings & Reviews

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.

Engine runs quieter

I’ve been using Amsoil in all my Harley’s since 2004. I believe this is the best oil you can buy.

Use Amsoil in both my Harley Road King Classic and my Daughters Sportster, wouldn't use anything else. Had trouble using Harley Davidson Synthetic, seemed to burn about 1+ quarts between changes. Not any more with Amsoil..

No muss, no fuss, great performance and peace of mind. Changed my oil every spring, ride all spring, summer and fall on the twin cam and Evo, no oil related failures. (Even the cam chain tensioner didn't look all that bad on the twin cam, replaced it though at 30k miles because I was in there making sure everything was on the up and up)

good stuff as always. wont put anything else in my 2014 ultra classic

I have always used this oil in my Road King custom and wouldn’t use anything else. As my bike is air cooled I like the idea of a synthetic oil versus a standard mineral oil. I feel it performs better especially in hot weather or when pulling my tent trailer.
