Transmission Oil - Honda CRF150R 2020 Owner's Manual & Competition Handbook

Transmission Oil

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.
