Engine Oil & Filter - Honda TRX400X Owner's Manual

Engine Oil & Filter
Engine oil quality is a major factor that affects both the performance
and the service life of the engine.
Using the proper oil (page 93 ) and filter, and regularly checking,
adding, and changing oil will help extend your engine's life. Even the
best oil wears out. Changing oil helps get rid of dirt and deposits in the
engine. Operating the engine with old or dirty oil can damage your
engine. Running the engine with insufficient oil can cause serious
damage to the engine and transmission.
Change the engine oil as specified in the maintenance schedule on
page 80 . When running in very dusty conditions, oil changes should be
performed more frequently than specified in the maintenance schedule.
