Always recycle used motor oil.
Many auto supply stores, car care centers, and gas stations accept used oil.
“Vehicle maintenance” is the first chapter in the Philadelphia Water Department
Office of Watersheds’ 2006 Homeowner’s Guide to Stormwater Management.
That’s because a single quart of oil can pollute 250,000 gallons of drinking water
(NDRC, 1994), and it’s estimated that each year over 180 million gallons of used
oil is disposed of improperly (Alameda CCWP, 1992).
Check your car or truck for drips and oil leaks regularly, and fix them promptly. In
case of a leak, or if you’re doing engine work, use a ground cloth or drip pan
under your vehicle. Never pour motor oil, antifreeze, transmission fluid or other
engine fluids into road gutters, down the storm drain or catch basin, onto the
ground, or into a ditch.
