Customer Ratings & Reviews

good stuff for all seasons. ice fishing to summer fun. Keep up the R&D guys!!

I run AMSOIL in all my stuff. Its been the best oil I've used. I've been running it in my race quad for 7 years and haven't had a single issue.

Great oil for my rzr 900s!

I changed from POLARIS oil to AMSOIL IN MY RZR. The motor sounds much quieter Only oil I'll use from now on.

Worth every penny, even the wife noticed the motor running better

I use it exclusively in my Polaris Ranger. Terrific oil.

Amsoil lasts longer, does not deteriorate as quickly as other oils, withstands heat, pressure, and the elements. I use amsoil oils and grease for everything.

Its one of the best true synthetic oils out there!

This product continues to prove itself in our race machines and never lets us down

While riding in WV, my tires threw a rock into my radiator and I lost all my coolant. I had to ride about 7 miles back to my truck with the overheat light on. Once I got the leak fixed, the engine still has good power and doesn't burn any oil. A big thanks to Amsoil for keeping my engine protected and lubricated through all of this.

My 2015 Polaris RZR 1000 runs better with Amsoil 5W-50 Synthetic and I can literally feel the difference in how well it performs. I run my RZR hard every chance I get and Amsoil has never let me down. This is the best oil that I have ever used and I highly recommend it to everyone who rides an ATV/UTV.

Signature 5w-50 in my Geo Tracker made it run smoother, quieter ,and cooler. I'm sold.

both of my 4-wheelers start in zero temps outside just like warm summer weather startups. Polaris a.t.v.'s and u.t.v.'s use the 5-50 viscosity oil that amsoil now makes.

I used this oil based on recommendations from the Kawasaki forums. As with all of the Amsoil oil products that I use, in my off-road vehicles in my pick up truck for heavy towing, it stands up excellent ! The ATV oil even after year and 4 months, had excellent lubricity and it was still very clear and clean. I'll continue using this in my Kawasaki Terex for as long as that I own it.

used the UTV oil in after break-in period and the engine noise was practically gone. First time user of Amsoil, and after that I am planning on switching over all of my toys.

Got this for a friend to run in his side by side

I have been using Amsoil in all of my power equipment for the past 25 years. This is the first year I have used this particular Amsoil product in my 2002 Honda Foreman ATV. I host an annual spring ATV ride with a bunch of my friends in some pretty rugged terrain. After a 6 hour ride through swamps, mud holes and everything in between, my friends and I were amazed not once, did my ATV fan turn on. This product exceeded my expectations.

Always use the best!!!

Great stuff! I use it in every thing I own.

Best Synthetic ATV/UTV oil available!!
