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.
