Engine 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 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.
