A well-maintained car can reduce emissions by up to 10 percent. Have a thorough tune-up every 6,000 miles or so. Dispose of all auto wastes safely. Recycle used oil. Never dump oil down a storm drain or pour it on the ground.
Improper disposal can lead to serious water pollution.
Use a hose with a shutoff nozzle when washing cars. Runoff from driveways flows down the street into a storm drain, through the storm sewer system, and directly into waterways without treatment. Have a supply of litter bags in the car. So before you start packing, make sure your car is ready for the trip.
