Engine Oil - Honda CRF450R 2011 Owner's Manual

Engine Oil

Refer to Safety Precautions on page 27.
Using the proper oil, and regularly checking,
adding, and changing oil will help extend the
service life of the engine. Even the best oil wears
out. Changing oil helps get rid of dirt and deposits.
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.
