Improving fuel economy not only saves drivers money, it also benefits the environment by releasing fewer emissions into the air and reduces a nation’s dependence on oil and oil imports. Reducing the amount of driving we do — by carpooling, using public transportation and combining trips — has the greatest effect on how much gas each person uses. That said, there are many ways to improve fuel economy when we do drive. These primarily involve driving more efficiently and making sure our cars are properly maintained.
Go easy on the pedals
Speeding, braking and rapid acceleration waste gas. Depending on the type of vehicle, poor driving habits can negatively affect fuel economy between 5 percent and 33 percent. Based on the current national average of $3.12 per gallon (for regular gasoline), driving sensibly, and not like a race car driver, can lead to an equivalent gas savings of between 16 cents and $1.03 per gallon.
Gas mileage decreases above 60 miles per hour. According to fueleconomy.gov, for every five miles per hour that exceeds 60 mph, drivers pay an equivalent of about 24 cents more for each gallon of gas. While each vehicle has its own optimal speed for fuel efficiency, speeding can result in 7 percent to 23 percent reduced fuel economy. Driving at slower speeds can save 21 to 71 cents per gallon.
Leave extras at home
An additional 100 pounds in your car can reduce gas mileage by up to 2 percent. The reduction is relative to the vehicle’s weight: Smaller vehicles are more affected by increased weight than larger ones. For every 100 pounds in extra weight, plan on spending up to 6 cents more per gallon.
Use cruise control (when appropriate)
According to Edmunds.com, using cruise control under appropriate conditions (avoiding use during especially hilly terrain) can improve fuel economy by up to 14 percent. That’s a savings of about 43 cents per gallon.
Turn off the car
Idling gets zero miles per gallon and collectively consumes several billion gallons of fuel per year, according to the U.S. Department of Energy. The California Energy Commission advises that vehicles should be turned off if the expected wait will be longer than 10 seconds, since an idling vehicle can burn as much as one gallon of gas each hour. Turning the car off can save about 5 cents per minute.
Check tire pressure
A little bit of vehicle maintenance can go a long way in improving gas mileage. According to the U.S. Department of Energy, 1.25 billion gallons of gasoline — approximately 1 percent of total consumption — are wasted each year on underinflated tires. Tires can lose about 2 pounds per square inch per month. Each tire that is underinflated by 10 psi reduces fuel economy by about 3.3 percent. Four tires that are underinflated by 10 psi, then, would reduce a vehicle’s fuel economy by a substantial 10 percent at an added cost of 31 cents per gallon.
Follow the guidelines in your vehicle’s owner’s manual (these recommendations also appear on a sticker inside the driver’s side door jamb) — and not what is stamped onto the tire itself.
Replace spark plugs
The National Institute for Automotive Service Excellence indicates that bad spark plugs can decrease fuel economy by up to 30 percent, and can cost drivers up to about 94 cents per gallon at today’s prices. If a car’s gas mileage suddenly drops, there’s a good chance it’s because of misfiring spark plugs.
Misaligned tires drag instead of roll freely. Improper alignment can reduce fuel efficiency by as much as 10 percent — about 31 cents per gallon. In addition, the tires can wear out more quickly. Tires that are out of balance (symptom: vibration in the steering wheel) can cause uneven tire wear, which can result in lower gas mileage. Tires should be balanced and rotated according to the vehicle’s owner’s manual to improve tire performance and fuel economy.
Fill your tank early in the morning or late at night
Fuel is dispensed by volume. If you fill your tank when it is coolest outside — early in the morning or late at night, and avoid the heat of the day — the fuel will be more dense. As a result, you will get more gas for the same amount of money.
Reducing the amount of driving we do, whether it’s by carpooling or foregoing an unnecessary trip, is perhaps the most effective way to decrease the amount of gas that each person uses and make fill-ups at the gas station last longer. Proactive steps can be taken to improve fuel efficiency by paying attention to and changing gas-guzzling driving habits, and following a vehicle’s maintenance schedule. Improved gas mileage is good for you, good for your car and good for the environment.
Keeping your vehicle in great mechanical condition will help improve your gas mileage and emissions, as well as prevent you form being stranded. All Tech Auto Repair does a free 35 point inspection with all our oil changes and many other services that we provide. We would be happy to asses the running condition of your vehicle and make sure that it is in top shape as we are approaching spring.
