What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by taking it
to a place that collects used oil. If you have a problem
properly disposing of your used oil, ask your dealer, a
service station or a local recycling center for help.
Engine Air Cleaner/Filter
See Engine Compartment
Overview on page 5-14 for
location of engine air
cleaner/filter and change
indicator (if equipped).
When to Inspect
If your vehicle is equipped with a filter change indicator
it lets you know when the filter needs to be replaced.
Vehicles with a restriction indicator, inspect the air
cleaner/filter at every oil change and replace the filter
when the indicator tells you to. Vehicles without a
change indicator, inspect the air cleaner/filter at every
oil change and replace it at the first oil change after
25,000 miles (40 000 km).
