We have used this product for 3 years on our XC race quads. We get excellent clutch life and motor life using Amsoil 10w-40 oil. Our engine builder always comments on how clean our motors are. I highly recommend this oil.

Been using Amsoil on all my race machines and daily drivers for years. Best lubricants on the market!

The only oil I use in my off-road vehicles!

Excellent product, very highly recommend. I race Pro-Am Atv-Mx, and it took my clutch from lasting one day before it started slipping, to where I could run the same clutch a whole national weekend - (3 days).

I purchased this oil based on the review of fellow Honda pioneer 1000 owners. This oil has made my shifting much smoother and quieter. It has surpassed my expectations from a motor oil. Will deff continue to use!

So far I really like the way my Ranger is running on the Amsoil it’s definitely different from the factory Polaris oil for sure. Now Im going to change out the oils in the diffs and see if that improves it as well. Great stuff so far glad I gave it a shot.

Everything runs smoother

I used this oil in my 2016 pioneer 1000 and it made a huge difference in the smoothness of the clutch engagement. Can't say enough good things about this oil.

Good

i use this on my two Polaris ATV's and Polaris UTV. So far so good!

Best oil on the plant period.

I have used this oil for many years now and have not had any problems. My old bike is still running great.

Great oil, seems to help make it more throttle responsive and lower idle RPM.
