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.)
