Oil and Maintenance Guide for 2009 Arctic Cat 400 4x4 H2 376
Before You Service the Engine
Before servicing the 2009 Arctic Cat 400 4x4 H2 376, confirm the lubricant requirements and prepare to verify the final fluid level. Before removing the drain plug, identify the correct refill and level-check procedure; a published capacity does not necessarily equal the amount needed after a routine drain.
What type of oil does a 2009 Arctic Cat 400 4x4 H2 376 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.
What oil filter is listed for a 2009 Arctic Cat 400 4x4 H2 376?
AMSOIL’s vehicle application catalog lists EAOM109-EA as oil-filter options for this model. Confirm the exact model and engine configuration before ordering.
Does synthetic oil automatically mean an ATV can go longer between oil changes?
No. The oil-change interval also depends on the engine, operating conditions, and manufacturer requirements. A synthetic product listing does not establish a longer service interval for this particular model.
