If you are a
shade tree mechanic and work on your own vehicle, it takes special
handling to deal with the used oil you take from your vehicle. Ask
your local garage dealer where you can safely and properly dispose
of your used oil.
For your information,
the Pennsylvania DEP has a wealth of information on how you can
get rid of your used motor oil. Simply go to the appropriate DEP
site and get rid of that old oil the right way.
