Fuel Efficiency
Save fuel, save money and reduce air pollution
Maintain Your Vehicle
A well-maintained vehicle can run more efficiently, use less fuel and produce fewer emissions. Regular maintenance also helps keep your car safer and can extend the life of your vehicle.
Fuel-saving maintenance tips:
- Use the manufacturer’s recommended grade of motor oil for your vehicle
- Look for motor oil marked “Energy Conserving” on the API performance symbol
- Keep your tires inflated to the proper pressure (can improve your gas mileage by up to 3%)
- Keep your engine properly tuned
- Fix maintenance issues promptly, especially problems that affect emissions or performance
Drive Smarter
Driving habits have a big impact on fuel use. Aggressive driving, including speeding, rapid acceleration and hard braking, can reduce gas mileage by 15% to 30% at highway speeds and by 10% to 40% around town. Gas mileage also usually decreases quickly at speeds above 50 mph, and according to the U.S. Department of Energy, every 5 mph driven over 60 mph is like paying an additional $0.22 per gallon for gas.
Driving more smoothly can help improve fuel efficiency, lower costs and cut emissions.
Fuel-efficient driving tips:
- Avoid rapid acceleration and hard braking
- Observe the speed limit
- Use cruise control on flat highway stretches when appropriate
- Avoid excessive idling
- Turn off your engine when parked
- Combine errands into one trip when possible
Choose Efficiency When You Can
When it is time to buy or replace a vehicle, choosing a more fuel-efficient option can help reduce fuel costs and emissions over time. For example, the cost savings between a car that gets 20 mpg and one that gets 30 mpg can amount to $1,038 per year, based on 15,000 miles of driving annually and a fuel cost of $4.15 per gallon. That’s $5,190 in your pocket over five years!
Electric, hybrid and other efficient vehicles may offer long-term savings while helping reduce air pollution. Use the U.S. Department of Energy’s FuelEconomy.gov resources to compare fuel costs, mileage and efficiency before making your next vehicle decision.
