Customer Ratings & Reviews

Just knowing I have access to the best oil products on the market is reasuring. Having air-cooled engines in my bikes,It is important. Used it in my Evo and Twincam motors.

I run nothing but 20/50 amisoil in my opinion it's the best I have 62.000 Miles all under amisoil

I only use AMSOIL 20x50 on my Harley road king police And I use 10x30 in cadilac dts only ,I put the best in the best

I use this oil in my 1999 BMW K1200RS water cooled engine. If it is tough enough for a Harley air cooled V-Twin it's got to be bullet proof in a water cooled engine.

use this in my 2016 street glide motor runs quieter and cooler

As far as i'm concerned there is no finer product on the market

Best oil on the market

I like that it doesn't have to be changed as often as other oils

RUNS COOLER BETTER MILEAGE LONGER TIME BETWEEN OIL CHANGES

I use this product in my 2002 Harley Davidson Road King. Love the product and the fact that I can get it sent right to my home.

Changed all the fluids on a H-D Ultra classic, Crank case, transmission, and Primary, ran the bike through the Arizona and Nevada deserts this August in the heat wave of the summer. Bike ran great and the transmission now shifts easier and quieter

My Harley is my Life 46000 miles ss Gear Cam's and SS adjustable rod's has many more upgrades is very aggressive I demand a trusting oil Thank You

All of my bikes have run between 8-11 degrees cooler with the Amsoil. That alone is Priceless!

I love Amsoil. It has been in all my motorcycles. It's well worth the money.

This oil far surpasses my expectations, my Harley has the engine management system; when it hits a certain temperature, the rear cylinder shuts off in stop and go traffic, with this oil, even here in Arizona with the extreme heat, the rear cylinder has not shut off since I started using Amsoil.

I used to product in all of my motorcycles since 2003 in the summer are you straight 60 towards the fall and winter go back to the 20/50. Since I started using this product and spoken about it to other bikers discovered that they decided to use Amsoil also completely satisfied with product will not use any other oil

Great product, minimal engine metal in filter upon 2nd oil change at 4000 miles. Will be ordering again very very soon.

I only use amoil in everything I have

This package of v twin oil was the perfect solution for harley Fat Boy. The right spec the right size with a little left over for top ups if ever necessary. The quality of thus product is very apparent as well bikd runs smother and cooler.

Awesome protection year round.
