Customer Ratings & Reviews

Running Amsoil gives me confidence I can continue to ride all over the country without worry of engine wear issues. Immediate delivery of every order is another bonus with Amsoil.

Both my bikes.. all I buy. Shipping should be free..

It seems to make the engines run cooler and shift smoother

There's no other engine oil that I would put in my Harley!

I ride my Dyna hard. I recently switched to Amsoil. My bike runs cooler and the valvetrain is quieter than with the former dealer brand. The only thing I wish is that the v twin oil change kit had the choice of black oil filter.

I have been an AMSOil user for many years- in my cars, trucks, drag race cars, and my motorcycles. I have lived in South Texas, Northern NH, and now, the Tampa Bay area. They are the best lubricants I have ever used and notice the difference in the engines, transmissions, and differentials. These products perform as they are desribed!!

The flexibility to use this on all of my bikes and their different components make it a must have.

I cannot express how well this oil performs. It provides smooth shifting and has actually quieted my tranny down considerably. There is also zero burnoff. Love this oil.

Outstanding product and great protection.

I have been using 20W-50 Amsoil Motorcycle oil for the last 150,000+ miles in the motor of my 2007 BMW R1200RT. I change oil every 6,000+ miles and the oil usage has been unchanged. I can highly recommend this product.

Amsoil is the best oil I have ever used, it has longevity and helps keep your engine clean. I can get more kilometers between oil changes, all in all this is the perfect oil!

Engine oil for 2016 FLS Slim.....newer engines run hot and need this oil....

Been using this oil in my Harley's since 2008. Would never think of using anything else.

To keep my bikes running perfectly.....frank hope is my go to guy and he's very easy to get in touch with and very friendly...

I love Amsoil 20w50 in my primary and oil tank in my Buell XB. Cool running engine, smoother shifts. Amsoil is great!

Great product will never use anything else in my Harley!!

I have run this oil in a high compression Harley engine for 50K miles without a problem. Have run in extreme heat without engine failure.

I use this in all of my motorcycles. When I purchased my Streetglide in 2015, the dealership performed an oil change. When the summer came and I got stuck in traffic, the bike started knocking bad when accelerating. That week I switched to what I use in my other bike and have not had that issue since.

I have used this product for over 15 years in my 3 Harley's, one of which has over 40k. Wouldn't use any other MC oil.

I have been using this for years in my Harleys - wouldn't use anything else.
