As Gasoline Prices Explode, See 30 Ways to Increase Vehicle Efficiency

WORCESTER – As American and Israeli attacks on Iran continue, the price of crude oil, and by extension, gasoline prices are exploding.

Crude oil prices increased by around 30 percent last week, the biggest weekly gain since 1983. On Sunday, crude oil prices surpassed $100 a barrel.

Increases in gasoline prices followed, with the national average for a gallon of regular unleaded increasing over 15 percent in the last seven days. That increase is the highest since 2022, when gasoline prices increased 60 cents in the week following the Russian invasion of Ukraine in March.

One week ago, on March 2, consumers paid an average of $2.91 per gallon of regular unleaded in Massachusetts. That price only increased a single penny over the prior month.

On March 9, the average price of a gallon of regular unleaded rose 40 cents to $3.31 per gallon. Nationwide, the average increased 48 cents since a week ago. In the Worcester metro area, prices have increased at nearly the same rate as the statewide average, from $2.91 a week ago to $3.32 on March 9.

Tips to Maximize Your Miles Per Gallon

With the increased financial burden on drivers and commuters, AAA Northeast provides the following tips to maximize the efficiency of the fuel you use in your vehicle.

• Avoid buying gas when there’s a delivery truck at the station. Recent deliveries stir up sediment, which can clog your fuel filter.
• Annual tuneups and inspections are vital. Check your vehicle’s owners manual for recommended maintenance intervals and be sure to inspect suspension and chassis parts for possible misalignments. Problems such as bent wheels, axles, bad shocks and broken springs all create engine drag (and are unsafe when traveling at high speeds).
• Avoid overfilling your gas tank, which can cause spills and waste. Never fill the gas tank past the first “click” of the fuel nozzle.
• After filling up, make sure the gas cap clicks three times. Improperly sealed gas caps allow fuel to vaporize and could even trigger your check engine light.
• Properly inflated tires are safer, last longer and can improve your gas mileage by more than 3%, according to the Department of Energy. Check your tire pressure at least once a month and compare it with the recommended pressure listed in your owners manual and on the placard in your car door. Inflate your tires as needed and be sure to check tire pressure when your tires are cold. A good time to check is early in the morning after your car has been idle overnight.
• Save money with self-service whenever possible and choose to pay in cash if there is an extra charge to use a credit card.
• Keep your eyes open to find good prices at the pump. You could even apply for a credit card which offers gas savings when using the card for purchases.
• Keep windows closed when traveling at highway speeds. Open windows cause aerodynamic drag, which consumes fuel.
• Think ahead when approaching hills. Only accelerate before you reach the hill, not while you’re on it.
• Slow down! Although vehicle reach their optimal fuel economy at different speeds, gas mileage usually decreases rapidly over 60 mph.
• Both acceleration and deceleration waste fuel. Try to drive at a constant speed and avoid tailgating. The driver in front of you could be unpredictable, making you brake or speed up more than necessary. Plus, it’s dangerous.
• Use cruise control whenever possible. The small, more precise adjustments made by the car’s cruise control system will keep your speed constant and save you fuel.
• Even on cold mornings, avoid warming up your engine at idle. Today’s cars are designed to start and go, saving you gas.
• If you have a manual transmission, don’t keep your left foot on the clutch pedal while driving. The slightest pressure puts mechanical drag on components, wearing them down prematurely.
• Avoid driving along rough roads whenever possible. Dirt and gravel can cost you on gas mileage.
• Use alternate roads when they prove to be safer, shorter and straighter. Corners, curves and lane jumping all require extra gas. The shortest distance between two points is always a straight line.
• Traffic lights are generally timed for your motoring advantage. By traveling steadily at the legal speed limit, you increase your chances of getting more green lights throughout your trip. Pay attention to the lights on your daily commute and try to anticipate whether they’ll turn green or red by the time you get there.
• Gas stations near major highways often charge more for gas because land is generally more valuable in these locations, increasing overhead costs. Those higher costs are passed on to consumers. Before a road trip, fill up at your local station. If you must fill up near the highway, try stations near state border lines, which tend to price their gasoline less aggressively.
• Remove snow tires during good weather seasons; traveling on deep tire treads hurts your fuel economy.
• Operating the air conditioner on the maximum level can reduce your mpg by 5% to 25%, compared to not using it. Try to park your car in the shade so you won’t have to keep the AC working as hard. Turn off the air conditioning five minutes before you reach your destination.
• Remove excess weight from the trunk or inside of the car: extra tires, child seats, unnecessary heavy parts, etc. Extra weight reduces mileage, especially when driving up inclines.
• On large sport-utility vehicles and minivans, one of the simplest gas saving tips is to remove unneeded third-row seating. Some third-row seats weigh over 100 pounds. This is extra weight your engine has to deal with, which can waste gas.
• Carpools reduce travel monotony and gas expenses. They also reduce traffic congestion.
• Combining errands into one trip saves you time and money. Several short trips taken from a cold start can use twice as much fuel as a longer multi-purpose trip covering the same distance with a warm engine. Trip planning ensures that traveling is done when the engine is warmed-up and efficient.
• Turn off your engine when your car is just sitting. Idling burns 1 gallon of gas per hour and will earn you zero mpg. You’ll not only save fuel, but you’ll also help the environment by not releasing more emissions from your car than absolutely necessary.
• Wax your car and keep it clean. This will reduce aerodynamic drag, thus providing better mileage.
• Walk between stops. Once you get into town, some of your stops may be near each other. Park between some or all of them and walk or park in the first spot you find. If you wander all over the parking lot looking for a really close parking space, you’ll use more gas.
• Track your mileage in real time. You may know what your consumption looks like from tank-to-tank, but that’s really not enough. Knowing the mileage you’re getting in real time and comparing it to what you got yesterday is one of the most useful gas saving tips you can practice.
• Run errands during off-peak traffic hours. These days, many offices offer more flexible hours, so errands can be run at almost any time. Avoid being stuck in traffic if all you have to do is leave 30 minutes earlier or come in 30 minutes later.
• Try to purchase vehicles that get good gas mileage. The difference between 20 and 40 mpg can be big for your wallet.
• Don’t use premium fuel if it’s not necessary. If your car specifies regular fuel, don’t buy premium under the mistaken belief that your engine will run better. Most cars are designed to run just fine on regular gasoline. Check your owners manual to find out what grade your car requires.
• Use your garage. Parking there will help your car stay warm in winter and cool in summer, so you don’t have to depend as much on your air conditioning when you drive.
• Try to avoid traffic on busy days or times when it is raining, windy or barometric pressure is high. Rain and high barometric pressure create extra air drag that uses more fuel to create and maintain forward motion.
