Oil and Maintenance Guide for 2011 Arctic Cat 350 366
Before You Service the Engine
When servicing the engine on your 2011 Arctic Cat 350 366, it is important to verify the correct lubricant and refill steps. Check the specific procedure for refilling and checking levels before you pull the drain plug, as a published capacity might not represent the exact amount required after a standard drain.
What type of oil does a 2011 Arctic Cat 350 366 take?
The available oil-product listings include Formula 4-Stroke Power Sports Synthetic Motor Oil. For a service, choose oil that meets the engine’s actual application requirements, not just a product name.
How much oil does a 2011 Arctic Cat 350 366 take?
The engine-oil capacity is listed as 3 quarts. Since the amount needed after a routine drain may vary from this figure, follow the proper level-check procedure when refilling.
Why does four-stroke engine oil need the right application rating?
Engine oils vary based on their additive packages and friction characteristics. Because some powersports engines use the same oil for both the engine and a wet clutch or transmission, it is important to match the manufacturer's specific requirements alongside the correct viscosity. This listing does not confirm the specific clutch design of your vehicle.
