AMSOIL Polaris® ATV/UTV oil change kits: which kit fits your machine

Which AMSOIL kit fits my Polaris?

Find your machine, then order that kit. This is AMSOIL’s published fitment list, sorted by model. Model names are written the way AMSOIL lists them.

PK1 does not fit turbo models; the RZR 1000 Turbo takes PK4. If your model or year is not in the table, run it through the lookup instead of guessing.

What’s in each kit?

Every Polaris kit is one box with AMSOIL 5W-50 Synthetic ATV/UTV Motor Oil (2.5 quarts in PK1, 2 quarts in PK2 and PK3, 3 quarts in PK4), one oil filter, and one drain-plug washer. AMSOIL says the filter uses cellulose media and meets or exceeds Polaris OEM filter standards. Pick the kit on the product page and it lists that kit’s contents.

PK1 vs PK2 vs PK3 vs PK4: what’s the difference?

Mostly fitment. All four use the same oil, AMSOIL 5W-50 Synthetic ATV/UTV Motor Oil. What changes is which machines the kit is listed for and how much oil is in the box: 2.5 quarts in PK1, 2 quarts in PK2 and PK3, and 3 quarts in PK4. PK1 is the 900 and 1000 side-by-side kit. PK2 is the Sportsman, Scrambler, and older-ATV kit, plus the RANGER 400 and 2016-and-earlier RANGER 500. PK3 is the mid-size kit. PK4 exists because PK1 does not fit turbo models: it is the RZR 1000 Turbo kit.

Running a Can-Am too? AMSOIL makes a separate set of kits for those: see AMSOIL Can-Am oil change kits.

Does the kit cover the transmission and front drive?

No. A kit is an engine-oil change: oil, filter, and washer. Polaris transmissions, gearcases, and front drives take their own fluids, and the right one depends on the model and year. AMSOIL’s UTV lookup and ATV lookup list them, and the ATV & UTV oil page covers the rest of the AMSOIL ATV line.

Running a Polaris through an Alaska winter

Around the Mat-Su, a RANGER or GENERAL is a work machine: plowing the driveway, hauling firewood, pulling a sled trailer to the trailhead. That is hard on oil in a way the odometer does not show. Short plow runs that never fully warm the engine let moisture and fuel collect in the oil. A few habits from years of doing this up here:

• If your owner’s manual has a severe-use interval, plowing and short cold runs are what it is for. Use it.
• Do the fall change before the machine sits, so it stores on clean oil instead of last season’s.
• Keep the kit somewhere heated. AMSOIL recommends storing lubricants at least 10°F above their pour point, and oil pours better warm anyway.
• Check the level the way your manual describes. Some Polaris engines have a specific warm-up and check procedure.

AMSOIL describes the oil in these kits as an all-season formula that performs in extreme heat and cold, with protection for demanding chores and tough terrain, and rust and corrosion protection for machines that sit.

How to change the oil with a kit

1. Run the engine a few minutes to warm the oil, then shut it off on level ground.
2. Pull the drain plug and let it drain. Install the new drain-plug washer from the kit.
3. Remove the old filter, wipe the base clean, film the new filter’s gasket with fresh oil, and install it as your manual specifies.
4. Fill with the oil from the kit, start the engine briefly, shut it off, and check the level the way your manual describes.
5. Check the plug and filter for leaks, and take the used oil and filter to a recycler.

Torque values and the exact procedure are in your owner’s or service manual. Follow those over any general list, including this one.
