Drive Wise

Transportation consumes about 25 percent of the total energy used in the United States. Driving releases harmful chemicals and other air pollutants into the air. When, where, how, why and what you drive all play an important role in affecting air pollution. Here are some suggestions on how to be more environmentally friendly when you need to get somewhere.

• Drive less, especially during peak traffic periods or hot days.
• Use public transportation, walk, or ride a bike.
• Shop by phone, mail or Internet.
• Telecommute. Even one day a week will make a big difference.
• Combine your errands into one trip.
• Avoid revving or idling engine over 30 seconds.
• Avoid waiting in long drive-thru lines, for example, at fast-food restaurants or banks. Park your car and go in.
• Accelerate gradually, maintain speed limit and use cruise control on the highway.
• Follow your owner's manual on recommendations for maximum economic efficiency.
• Use an energy-conserving (E.C.) grade of motor oil.
• Minimize use of air conditioning if you can.
• Get regular engine tune ups and car maintenance checks (especially for the spark plugs).
• Use EPA-certified facilities for air conditioner repair.
• Find out if materials are recycled when you change your tires, "throw away" your car or change car fluids. Ask before your car is serviced and consider going to someone who is environmentally friendly.
• Replace your car's air filter and oil regularly. For information of how to do this correctly and environmentally visit http://www.epa.gov/epaoswer/non-hw/recycle/recy-oil.pdf (PDF, 8 pp, 219 KB) .
• Keep your tires properly inflated and aligned.
• Repair all vehicle leaks promptly.
• Fill gas tank during cooler evening hours to cut down on evaporation. Avoid spilling gas and don't "top off" the tank. Replace gas tank cap tightly.
• Look for the most efficient, lowest-polluting model of vehicle. For more information visit the Green Vehicles Guide Web page - http://www.epa.gov/greenvehicles/
• Don't ignore the "check engine" or "service engine soon" light if it comes on. Make an appointment with your repair technician for diagnosis soon. For more information, read our fact sheet at: http://www.epa.gov/otaq/obd-faq.htm.
