Customer Ratings & Reviews

I've used this oil for my Victory for a few years now and the air cooled beast runs cooler and smoother. Best oil on the market.

Keeps the engine cooler

The only oil I put into my Harley Davidson.

Put this in my 2014 cvo breakout

Only product I use in our Harley Davidson motorcycles. White report says it all, Amsoil in consistanly the best product on the market today.

Runs cooler & quieter

I have a 2010 Harley-Davidson CVO FLSTSE Softail Convertible with the 110 Screamin Eagle engine. Synthetic oil is required for this engine. I've been using AMSOIL 20/50 Synthetic for over 5 years and will continue to do so.

For Hot temp riding, Amsoil 60 is a must.

I made the switch from the H-D oil to Amsoil and immediately noticed an improvement in overall performance and will never switch back to H-D oil! My Honda Civic with 160,000+ miles was really dragging to get going, but after switching my car to Amsoil it accelerates like new again. I have no complaints and will be an Amsoil customer for years to come!

I run this in the engine .trans and the primary.. does very well . The temps are down about 3 to 5% which on a air cool engines is alot....

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.
