How Rising Gas Prices Are Forcing Drivers to Rethink Everyday Habits — And 7 Ways to Cut Fuel Costs Now

DETROIT — Americans are staring down the barrel of soaring gas prices in 2026, with the national average hovering around $3.87 per gallon—up from $3.42 a year ago—and experts warn that prices could swing further due to geopolitical tensions, refinery disruptions, or seasonal demand spikes. For a typical driver who fills up a 15-gallon tank twice a month, that’s an extra $135 annually in fuel costs. But beyond the sticker shock at the pump, there’s a more immediate solution: drivers can stretch their fuel dollars by fundamentally changing how they operate their vehicles. Automakers and consumer advocates agree that small, deliberate adjustments in driving behavior and vehicle maintenance can yield measurable savings—sometimes boosting fuel efficiency by 10% or more. As Michael Crossen, manager of auto testing at Consumer Reports, put it: 'It’s not just about driving less; it’s about driving smarter.' From adopting fuel-efficient speeds to optimizing vehicle configurations, the strategies below are backed by engineers, automotive journalists, and real-world testing—proving that even modest changes can compound into significant savings over time.

Why Gas Prices Are Skyrocketing in 2026 — And What It Means for Your Wallet

The surge in gas prices reflects a confluence of factors. Global oil markets remain volatile due to OPEC+ production cuts, sanctions on key oil-producing nations, and underinvestment in new refinery capacity. Domestically, the transition to cleaner fuels and maintenance outages at aging refineries have tightened supply. In early March 2026, the Energy Information Administration (EIA) projected U.S. gasoline prices would average $3.90 per gallon through mid-year, with regional variations ranging from $3.65 in the Gulf Coast to $4.20 in California. AAA reported that nearly 60% of Americans have altered their driving habits in response to higher prices, with 34% reporting they’ve reduced non-essential trips. 'Consumers are feeling the pinch at every turn,' said David Bennett, senior automotive manager at AAA. 'But the good news is that many of the solutions don’t require buying a new car—they’re behavioral and mechanical.'

7 Proven Ways to Stretch Your Fuel — Backed by Engineers and Test Data

1. Slow Down: Drive at 65 mph on Highways for Maximum Efficiency

Modern vehicles are finely tuned to operate most efficiently at moderate speeds. Sean Tucker, managing editor for compact and full-size vehicles at Kelley Blue Book, emphasizes that aerodynamic drag increases exponentially with speed. 'A car’s fuel economy drops sharply once you exceed 65 mph,' Tucker said. 'At 75 mph, you could be losing up to 17% of your fuel efficiency compared to 65 mph.' Consumer Reports testing on a 2023 Toyota Camry showed a 14% improvement in fuel economy when cruising at 65 mph versus 75 mph on the highway. The reason? Higher speeds force the engine to work harder, consuming more fuel to overcome air resistance. For drivers on long commutes, this one change could save hundreds of dollars per year.

2. Use Cruise Control: Smooth Acceleration Saves Gas

Cruise control isn’t just a convenience—it’s a fuel-saving tool. By maintaining a constant speed, it eliminates the 'sawtooth' pattern of acceleration and deceleration that wastes fuel. AAA research shows that inconsistent driving can reduce fuel economy by 10% or more. Bennett advises using cruise control on open highways, especially when terrain is flat. 'Every time you press the gas pedal, you’re burning extra fuel,' he said. 'Cruise control helps you avoid unnecessary surges, particularly in stop-and-go traffic where braking and reaccelerating are frequent.' For drivers in congested urban areas, modern adaptive cruise control systems can further enhance efficiency by adjusting speed based on traffic flow.

3. Turn Off the Engine at Idle: Stop-Start Systems Work

Idling wastes fuel and increases emissions. Most newer cars come equipped with automatic start-stop systems that shut off the engine when the vehicle comes to a stop and restart it when the driver presses the accelerator. AAA estimates that idling for more than 10 seconds consumes more fuel than restarting the engine. 'Don’t disable your start-stop system,' Bennett urged. 'It’s designed to save fuel and reduce emissions during stops. Even in heavy traffic, it can cut idle time significantly.' For drivers without this feature, turning off the engine during long waits—especially when using air conditioning—can save up to 0.2 gallons of gas per hour of idling. That adds up quickly for delivery drivers, rideshare operators, and parents waiting outside schools.

4. Reduce Drag and Weight: Remove Roof Racks, Clean Out Your Trunk

Every extra pound and every square inch of aerodynamic drag costs fuel. Consumer Reports found that carrying an extra 100 pounds reduces fuel economy by about 1%, while a roof rack can decrease efficiency by up to 5%. 'It’s like pulling a parachute behind your car,' Crossen said. 'If you’re not using it, take it off.' Similarly, leaving golf clubs, tools, or unused luggage in the trunk adds unnecessary weight. A study by the Oak Ridge National Laboratory showed that reducing vehicle weight by 100 pounds improves fuel economy by 1% to 2%. For a driver averaging 12,000 miles per year, that could translate to 24 fewer gallons of gas consumed annually.

5. Keep Tires Properly Inflated: A Simple Fix with Big Payoffs

Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. The U.S. Department of Energy estimates that keeping tires inflated to the manufacturer’s recommended pressure can improve gas mileage by up to 3%—and up to 10% when correcting severely underinflated tires. Bennett recommends checking tire pressure every other gas fill-up using a reliable gauge. 'Don’t go by the tire’s sidewall markings alone,' he said. 'Those are maximum pressure ratings, not the optimal pressure for your vehicle. Always check the sticker on the driver’s door jamb or your owner’s manual.' Seasonal temperature changes also affect tire pressure: for every 10°F drop, tire pressure decreases by about 1 PSI. Regular maintenance—including alignment checks and tire rotations—can also prevent uneven wear that reduces efficiency.

6. Choose the Right Fuel: Not All Cars Need Premium

Some drivers habitually fill up with premium gasoline, believing it improves performance or longevity—even when their vehicle is designed for regular. AAA data suggests that 1 in 10 drivers unnecessarily uses premium fuel, costing an average of $150 more per year. 'Follow your owner’s manual,' Crossen advised. 'If it says ‘regular’ or ‘87 octane,’ that’s what you should use.' For cars that require premium, using a lower-octane fuel can cause engine knocking and long-term damage. Additionally, consider fuel quality. Top Tier gasoline—brands that meet higher detergent standards set by automakers like GM, Toyota, and Honda—can help prevent carbon buildup in engines. While not required during supply shortages, Top Tier fuel offers long-term benefits for engine health. Apps like GasBuddy can help drivers locate Top Tier stations and compare prices along their route.

7. Plan Smarter Trips: Combine Errands, Avoid Unnecessary Stops

Every unnecessary trip adds to fuel consumption and wear on the vehicle. AAA recommends consolidating errands into a single trip to reduce cold starts and warm-up cycles, which are less efficient. 'Don’t drive across town just to save a dollar on eggs,' Crossen said. 'Plan your route using apps that optimize stops, and avoid peak traffic hours when possible.' Carpooling is another effective strategy: splitting a 20-mile round trip with one other person can cut fuel costs by 50%. For families, coordinating school drop-offs or ride-sharing with neighbors can yield substantial savings. Even small changes, like parking once and walking between multiple stores, can add up. AAA calculates that reducing total annual mileage by 1,000 miles can save the average driver $150 in fuel costs.

When It’s Time to Upgrade: Hybrids and EVs Offer Long-Term Relief

For drivers whose vehicles are more than 10 years old, upgrading to a newer, more fuel-efficient model—or even a hybrid—can deliver substantial long-term savings. The average age of a car on U.S. roads is now 12.7 years, according to S&P Global Mobility, meaning millions of vehicles are operating well below modern efficiency standards. A 2025 Toyota Prius hybrid, for example, averages 52 mpg combined, compared to 28 mpg for a 2010 Camry. Over 15,000 miles, that’s a savings of 260 gallons of gas—or roughly $1,000 at current prices. 'Hybrids are a smart middle ground,' said Sean Tucker. 'They don’t require charging infrastructure, and they pay for themselves in fuel savings within a few years.' For those ready to go fully electric, used EVs like the Nissan Leaf or Chevrolet Bolt offer an affordable entry point, with federal tax credits available through 2032. However, experts caution that switching too soon—before a used EV meets your needs—could lead to higher long-term costs due to battery degradation or lack of charging access.

The Hidden Costs of Ignoring Fuel Efficiency

Beyond the direct expense of higher gas prices, poor fuel efficiency can lead to increased maintenance costs, reduced vehicle lifespan, and higher depreciation. Engines that run rich (using more fuel than necessary) or operate at suboptimal temperatures due to clogged air filters or faulty oxygen sensors can suffer accelerated wear. 'A poorly maintained engine doesn’t just waste gas—it can cost thousands in repairs down the line,' Tucker warned. Regular tune-ups, including air filter replacements and oxygen sensor checks, can restore fuel economy to near-original levels. AAA estimates that a properly maintained vehicle can improve fuel efficiency by 4% on average. Additionally, aggressive driving habits like rapid acceleration and hard braking can reduce brake life by up to 30% and increase tire wear.
