Before You Service the Engine
Before servicing the 2010 Arctic Cat 400 4x4 Auto TRV 376, confirm the lubricant requirements and prepare to verify the final fluid level.

How much oil does a 2010 Arctic Cat 400 4x4 Auto TRV 376 take?
The available engine-oil capacity figure is 3 quarts. The amount added during a routine drain may differ from the listed capacity; use the correct level-check procedure when refilling.
What oil filter is listed for a 2010 Arctic Cat 400 4x4 Auto TRV 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 using synthetic oil change the viscosity grade an ATV needs?
No. Synthetic describes how the oil is formulated; it is separate from the SAE viscosity grade. A synthetic oil still needs the appropriate grade and engine-application specifications.
