The Polaris Outlaw 90 is a small compact 89 -c all-terrain vehicle. This engine holds 1 1/2 quarts of four-stroke engine oil inside the crankcase. On the bottom of the crankcase is a half-inch nut, and on the side of the engine is a small chrome cap that is the oil cap. You will need some basic tools and about 10 minutes to change the oil. Also, this ATV does not have an oil filter.
Tools Used: Tools, Drain container, Ratchet, 1/2-inch socket, 1 1/2 quarts four-stroke engine oil
Change the Oil
Start the engine, and allow the engine to warm for 5 minutes. Turn the engine off, and place the drain container under the drain nut. Remove the drain nut using the ratchet and socket. Replace the nut once the oil has completely drained. Twist the chrome oil cap to the left, and pull it off the engine. Pour the engine oil into the crankcase, and then replace the cap to the engine.
