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.
