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 01 a local recycling
center for help.
