How to Improve Your Gas Mileage in 2026

If you’re doing a lot of driving around Marion, fuel costs can add up quickly. Whether you’re commuting to Bucyrus or heading down to Delaware, finding ways to improve your gas mileage is a smart move for your wallet and your vehicle’s longevity. Our certified service department is here to help you get the most out of every gallon. We’ve put together this comprehensive guide on how to increase fuel efficiency for your Chevrolet, GMC, or Buick vehicle.

How to Improve Gas Mileage With Smart Driving Habits

Adopting fuel-efficient driving habits is one of the most immediate ways any Galion driver can save money. Simple adjustments to how you handle the pedals can improve your MPG by 15% to 30% at highway speeds. Here are the best ways to improve gas mileage through your daily routine:

• Observe the Speed Limit: Most vehicles, including the Chevrolet Equinox, reach peak fuel efficiency at around 50 mph. Every 5 mph you drive over 50 is like paying an extra $0.20+ per gallon.
• Maintain a Consistent Speed: Fluctuating your speed wastes fuel. Utilize cruise control—or Super Cruise™ if your vehicle is equipped—on flat stretches of highway near Marysville to maintain a steady pace.
• Accelerate and Brake Gradually: “Jackrabbit” starts and hard braking significantly lower your fuel economy. Imagine an egg under your gas pedal and try to keep it from breaking.
• Reduce Idle Time: If you are stopped for more than 30 seconds (and not in traffic), turn off the engine. Modern GM engines use less fuel to restart than they do to idle. Many new models feature Auto Start-Stop technology to handle this automatically.
• Lighten the Load: An extra 100 pounds in your trunk can reduce your MPG by about 1%. Remove unnecessary cargo and take off roof racks or bike carriers when they aren’t in use to reduce aerodynamic drag.

How to Increase Fuel Efficiency With Regular Maintenance

A well-maintained vehicle is a fuel-efficient vehicle. Postponing service appointments makes your engine work harder, which burns more gas. To keep your GMC Sierra 1500 or GMC Acadia running at its peak, follow these maintenance tips:

• Keep Your Tires Inflated: Under-inflated tires increase rolling resistance. Check your tire pressure monthly, especially during Ohio’s seasonal temperature shifts. If you need a fresh set, visit our tire center.
• Regular Oil Changes: Using the manufacturer-recommended oil grade reduces friction in your engine. Schedule your certified service oil change to ensure your engine stays lubricated and efficient.
• Replace Air Filters: A clogged engine air filter restricts airflow, forcing the engine to use more fuel to compensate.
• Check Wheel Alignment: Misaligned wheels don’t just wear your tires; they create “drag” that forces your engine to work harder to move the car forward.
• Engine Tune-Ups: Replacing worn spark plugs and oxygen sensors can improve mileage by as much as 40%. Our team specializes in Chevrolet performance tuning to keep your vehicle in top shape.

Fuel Efficiency Frequently Asked Questions (FAQ)

Does using the AC lower gas mileage?
Yes, but it depends on your speed. At lower speeds around Upper Sandusky, rolling down your windows is more efficient. However, at highway speeds, the aerodynamic drag caused by open windows is actually worse for your MPG than running the air conditioning.

How much can a dirty air filter affect MPG?
While it varies by vehicle age, a severely clogged air filter can reduce fuel economy by up to 10% in older vehicles and impact acceleration in newer models.

Is “Premium Gas” better for gas mileage?
Unless your owner’s manual specifically requires premium fuel (typically for high-performance engines), using it will not improve your gas mileage or engine performance.

Does an oil change really help gas mileage?
Absolutely. Fresh, clean oil reduces internal engine friction. Following the recommended GM maintenance schedule ensures all components are working in harmony for maximum efficiency.
