Refer to Safety Precautions on page 19.
Using the proper oil, and regularly checking,
adding, and changing oil will help extend the
service life of the transmission and clutch. 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 and
transmission.
Oil Recommendation
• Your CRF does not need oil additives. Use the
recommended oil.
• Do not use oils with graphite or molybdenum
additives. They may adversely affect clutch
operation.
• Do not use API SH or higher 4-stroke engine
oils displaying a circular API “energy
conserving” service label on the container. They
may affect lubrication and clutch performance.

* Suggested 4-stroke engine oils are equal
