Oil Specifications for a Polaris Sportsman 500cc
by Brianna Collins
Polaris has been manufacturing the Sportsman ATV for decades. In fact, it was one of the company's first and best-selling utility quads. Polaris designed it to be particularly suited to trail riding, ATV hunting, and other heavy-duty applications. In 2010, as in other years, Polaris recommended specific oil maintenance and specifications for all Sportsman 500 trims.
Engine Oil
Polaris recommends Premium 4 Synthetic 0W40 as an engine oil, as it has been specifically engineered to work with Polaris four cycle engines. This is a synthetic, multi-viscosity oil with decent film strength over a wide temperature range from minus-40 to 120 degrees Fahrenheit. If this oil is not available, any API certified SH 0W-40 oil may be used. Polaris cautions against mixing oil brands, as this may result in "serious engine damage." Oil levels should be maintained between the two raised marks found on the dipstick. The 2010 Sportsman 500 has an oil tank capacity of 2.0 quarts or 1.9 liters.
Other Oils
Polaris AGL Synthetic Gearcase Lube is recommended as the transmission oil. Owners should ensure that transmission reaches to the fill hole threads at all times. Additionally, engine oil may be used as a general lubricant on any of the quad's moving parts.
Maintenance Specs
Polaris recommends that driver's check engine oil levels prior to each ride. Owners should also perform a break-in oil change every six months, at which time the oil filter should be changed. Additionally, transmission oil should be inspected every month, 25 hours of riding, or 250 miles, whichever comes first. It should also be changed yearly regardless of riding time. General lubrication should be performed on all fittings, pivots, cables and other moving parts at least every three months, 50 hours or 500 miles.
