Tech Tips - Gas Prices Rising - Fight Back With Better MPG

Bad driving habits have an impact on your car and the environment.

Avoid high speeds. Fuel efficiency decreases significantly at speeds over 55 miles per hour. In addition, high-speed driving causes heat buildup that accelerates tire deterioration. Cornering too fast causes excessive, uneven wear on tire treads.
Drive smoothly. Smooth driving saves gas and lowers vehicle emissions. You should accelerate slowly, avoiding “jackrabbit starts”; shift to higher gears at the lowest speed if you have a standard transmission; and accelerate gently if you have an automatic transmission. If your car is equipped with overdrive, you should use it at the appropriate speeds; if your car is equipped with cruise control, you should use it. Also avoid sudden starts and stops, which increase wear on your tires.
Avoid lengthy idling. Idling wastes gas. Don’t start your car until you’re ready to go, and keep winter engine warm-ups brief. Turn off the engine if you won’t be moving for an extended period of time-for example, if you’re in stalled traffic or a long line at a drive-in window.
Don’t rev the engine; it wastes gas. Revving the engine can dump gas on the cylinder walls, which increase engine wear. Revving can also overheat the vehicle’s catalytic converter, which makes it less effective and can damage it.
Minimize drag. Drag reduces fuel efficiency. Driving with the windows open, using roof- or rear-mounted racks, and carrying heavy loads increase vehicle drag. If you sometimes need to transport large items, use a removable rack or, if possible, carry the items in the trunk or inside the vehicle. And, because heavy loads increase drag, remove heavy items from the vehicle when you don’t need to carry them.
Keep tires properly inflated. Underinflated tires decrease gas mileage and shorten tire life. Newer cars have a label on the inside edge of the driver’s door that lists recommended tire pressures for different speeds & loads. (The maximum pressure, which is printed on the tire’s sidewall, may not be the optimum pressure for your vehicle or driving situation.) In some vehicles, the label may be on the door post, glove compartment door, or fuel door. If you cannot find the label, you should consult your owner’s manual or check with the vehicle manufacturer, tire manufacturer, or local tire dealer. Check the pressure in all four tires every two weeks with an accurate hand-held air pressure gauge. The gauges on service station air pumps may be inaccurate. Because tire pressure changes with temperature, you should check and adjust pressure when the tire is cold-when the vehicle has been sitting for at least three hours.
Avoid rough roads and potholes. Because driving on rough surfaces is hard on tires and wheel alignment, it can reduce fuel efficiency.
Make fewer trips in your vehicle. Vehicle emissions and fuel consumption increase not just with number of miles driven, but also with number of trips taken. Vehicles burn more gas and emit far more pollutants in their first few minutes of operation because their emission control systems have not warmed up and reached peak efficiency. To make fewer trips, you should consolidate errands and trips; try to drive during off-peak hours so that you can spend less time on the road and avoid excessive stop-start driving; and, when possible, car pool, ride mass transit, or bike to your destination.

Remember, paying attention to our vehicle’s maintenance can extend the life of the car, improve air quality, reduce negative health impacts due to emission pollutants, and save money.
