Before You Service the Engine
Maintaining the engine on your 2009 Can-Am Outlander 800 HO 4x4 EFI 800 requires using the right lubricant and double-checking the level after you refill. Since a published capacity might not match exactly what is needed after a routine drain, identify the proper refill and level-check procedure before you remove the drain plug.
How much oil does a 2009 Can-Am Outlander 800 HO 4x4 EFI 800 take?
The engine-oil capacity is listed at 2.11 quarts. Because the amount you add during a routine drain may differ from this figure, follow the correct level-check procedure when refilling.
What kind of oil does a 2009 Can-Am Outlander 800 HO 4x4 EFI 800 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.
Does synthetic oil automatically mean an ATV can go longer between oil changes?
No. Your oil-change interval depends on your specific engine, how it is operated, and manufacturer requirements. Using a synthetic product does not mean this model will have a longer service interval.
