Been using for 2 oil changes and atv runs fine

Since I started using AMSOIL, the oil’s performance is outstanding.

Been working on anything motorized for 35 years. During the trials of oils throughout the years, I kick myself for not using Amsoil since last year. Absolute BEST oils ever made. Everything runs cooler and clutch's are restored to like new conditions. I'll never go with any other brand.

Use in my air cooled engine and fan does not come on as often

I use Amsoil in my 2010 Honda 4wheeler because it has a tough life. It's HOT down here and we pull a furrow with the 4wheeler to smooth out the arena. Haul manure. Spray fence rows and with Amsoil it runs like it was new.

2021 Honda 1000/3 LE pioneer Changed all fluids to Amsoil. Put 10W-40 in the engine and transmission and it shift smoother and much easier. Switching all my UTV's to Amsoil, just wish I would of did it a year ago

Product is best on the market. Buy it it works! SXS runs smoother and has better performance.

Works great awesome product comes with a amsoil sticker recommend to other people

Great OEM replacement fluids and fast shipping

I’ve been running AMSOIL for several years now and I’ve never had a build up valve problems and never had a fouled spark. When it’s time for oil change the oil that comes out really looks better than oem oil you put in new. I recommend AMSOIL to everyone I can for any kind of engine, down to recoiling your guns they got it to. It’s better than the best you’ve ever could imagine.

This is better than OE Polaris oil. Hands down

Have used amsoil in my atvs and utvs for the last 8 years they get changed in the spring and run the rest of the year. All of my machines are used for towing and off road use I always run a high quality oil filter and have had no oil related issues with any of the machines

Great product , fast service with good shipping.

I have been impressed with quality of AMSOIL products. Thank you!

Noticed shifting in my sxs was smoother after switching to Amsoil.

This is in my RZR Pro. Works great for this high rpm motor. Change every 25 to 50 hours for best results.

I was glad amsoil had this product for my UTV. It saved me from having to buy at another location. I have not had any engine failures while using amsoil motor products.

Only a few hours shine change, but engine and transmission seem to run smoother.

Run the oil in my rhino and fan runs less plowing snow due to keeping engine cooler

Replaced honda synthetic oil in my utv 1000 pioneer with amsoil utv atv 10 w 40. Shifts a whole lot smother. This stuff works.
