Oil and Maintenance Guide for 2011 Can-Am DS 450 449
Before You Service the Engine
Routine maintenance for your 2011 Can-Am DS 450 449 requires using the right lubricant and carefully checking the level after refilling. Since a published capacity might not match the exact amount needed after a routine drain, identify the proper refill and level-check procedure before you remove the drain plug.
What type of oil does a 2011 Can-Am DS 450 449 take?
The engine-oil viscosity shown for this model is 10W-40. The available oil-product listings include Formula 4-Stroke Power Sports Synthetic Motor Oil, 10W-40 Synthetic ATV/UTV Engine 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 Can-Am DS 450 449 take?
The engine-oil capacity is listed as 1.9 quarts. Because the amount added during a routine drain may differ from this figure, follow the correct level-check procedure when refilling.
Why does four-stroke engine oil need the right application rating?
Engine oils vary by additive packages and friction characteristics. Some powersports engines use the same oil for both the engine and a wet clutch or transmission, so matching the manufacturer's specific requirements is just as important as choosing the right viscosity. This listing does not confirm your specific clutch design.
