What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don't let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner.
Wdsh or
properly throw away 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 real threat to the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don't
ever 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.
