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. Wash 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.
