Smart Driving Habits to Improve Gas Mileage

Your driving style has a profound impact on how efficiently your car uses fuel. Aggressive driving, characterized by rapid acceleration and hard braking, can lower gas mileage by 10% to 40% in city driving and 15% to 30% on highways. By adopting a more mindful approach behind the wheel, you can see significant savings.

Accelerate Smoothly and Brake Gently

Think of your accelerator pedal as a delicate instrument, not an on/off switch.

• Smooth Acceleration: Press down on the gas pedal gently. Rapid acceleration forces your engine to work harder and consume more fuel. Try to take about five seconds to bring your vehicle up to 10 mph from a standstill.
• Anticipate Traffic: Look ahead at traffic conditions. By anticipating stops and slow-downs, you can gradually ease off the accelerator and coast to a stop, rather than slamming on the brakes. This "anticipatory driving" reduces unnecessary braking and acceleration, which are major fuel guzzlers.

Maintain a Consistent Speed

Varying your speed constantly is inefficient.

• Use Cruise Control: On long, flat highway stretches, engaging cruise control helps maintain a steady speed, which significantly improves fuel efficiency. However, avoid using cruise control on hilly or slippery roads, as it can cause the engine to work harder or lead to a loss of control.
• Observe Speed Limits: While vehicles achieve optimal fuel economy at different speeds, gas mileage generally decreases rapidly above 50 mph. Driving just 5 to 10 mph slower than you normally would can result in a 7% to 14% savings in fuel economy.

Avoid Excessive Idling

Leaving your engine running while parked consumes fuel needlessly.

• Turn Off Your Engine: Idling can use a quarter to a half-gallon of fuel per hour, depending on engine size and air conditioner use. If you're going to be stopped for more than 10 seconds, it's more fuel-efficient to turn off your engine and restart it when you're ready to go. Modern vehicles are designed for frequent starts and stops.

Optimize Air Conditioning Use

Air conditioning (A/C) puts a greater demand on your engine, increasing fuel consumption.

• Use Wisely: On very hot days, A/C can reduce fuel economy by up to 25%. At lower speeds (e.g., city driving), consider rolling down your windows to cool the cabin. At higher speeds (highway driving), using the A/C with windows closed can be more efficient than open windows, which create aerodynamic drag. Parking in the shade can also help reduce the need for full-blast A/C.

Essential Vehicle Maintenance for Better Fuel Economy

A well-maintained vehicle runs more efficiently, directly translating to better fuel economy. Regular tune-ups and checks are among the best ways to boost your fuel economy.

Check Tire Pressure Regularly

This is one of the simplest yet most impactful maintenance tasks.

• Proper Inflation: Underinflated tires create more rolling resistance, forcing your engine to work harder and consume more fuel. Properly inflated tires can improve gas mileage by up to 3% on average.
• How Often? Experts recommend checking your tire pressure at least once a month and before long trips. You can find the recommended PSI (pounds per square inch) in your owner's manual or on a sticker inside the driver's door jamb.

Perform Regular Engine Tune-ups

Keeping your engine in top condition is crucial for optimal fuel efficiency.

• Spark Plugs: Worn spark plugs can lead to incomplete combustion, wasting fuel. Replacing them allows your engine to run cleaner and optimizes fuel economy.
• Air Filters: A dirty air filter can restrict airflow to the engine, making it work harder. Replacing a clogged air filter can improve fuel economy and acceleration. Some sources suggest a clean air filter can improve gas mileage by as much as 10%.
• Oil Changes: Regular oil changes with the manufacturer's recommended grade of motor oil reduce friction in the engine, improving efficiency. Look for "Energy Conserving" motor oils, which contain friction-reducing additives.

Reduce Excess Weight and Aerodynamic Drag

Every extra pound your car carries, and every bit of wind resistance it faces, reduces fuel economy.

• Declutter Your Vehicle: An extra 100 pounds in your vehicle can reduce your MPG by about 1%. Regularly clear out unnecessary items from your trunk and backseat.
• Remove Roof Racks and Cargo Boxes: These add-ons significantly increase aerodynamic drag, especially at higher speeds, and can lower fuel economy by 6% to 17% on the highway. Remove them when not in use.

Other Smart Strategies to Save on Fuel

Beyond driving habits and maintenance, a few other considerations can help you achieve the best ways to boost your fuel economy.

• Plan Your Trips: Combine multiple errands into one trip to reduce the number of "cold starts," as a cold engine is less efficient. Using navigation apps to map fuel-efficient routes can also minimize unnecessary driving.
• Use the Right Fuel: Always use the octane level recommended in your vehicle's owner's manual. For most standard cars, using premium gas when it's not required offers no benefit in terms of fuel economy and is just a waste of money. Premium gas is primarily designed for high-performance engines that require higher octane to prevent engine knock.

Conclusion

Boosting your fuel economy is a practical and effective way to save money and contribute to a healthier environment. By consciously adopting fuel-efficient driving habits, diligently performing regular vehicle maintenance, and making smart choices about your vehicle's load, you can significantly reduce your fuel consumption. Every small change adds up, leading to noticeable savings at the pump and a longer, healthier life for your car.

Frequently Asked Questions (FAQ)

Q1: Does using premium fuel improve gas mileage?

A1: For most standard cars, no. Using premium fuel (higher octane) when your owner's manual recommends regular unleaded will not improve your gas mileage or performance. Premium fuel is only beneficial for vehicles specifically designed to require it, typically high-performance or turbocharged engines, to prevent engine knock.

Q2: How much money can I really save by improving my fuel economy?

A2: The savings can be substantial and depend on factors like your current vehicle's MPG, how much you drive, and gas prices. For example, changing from a vehicle that gets 17 MPG to one that gets 48 MPG could save over $1,100 per year for someone driving 15,000 miles annually with gas at $2.00 per gallon. Even small improvements in driving habits or maintenance, like properly inflating tires (up to 3% better mileage), can lead to noticeable savings over time.

Q3: Does running the car's air conditioning significantly affect fuel economy?

A3: Yes, running the air conditioner does affect gas mileage. It can reduce your vehicle's fuel economy by up to 25% in very hot weather, especially in city driving or stop-and-go traffic where the engine's demand for power is more noticeable. On highways, the impact is generally less pronounced. To balance comfort and fuel efficiency, consider opening windows at lower speeds and using A/C more sparingly or on recirculate at higher speeds.

Q4: How often should I check my tire pressure for optimal fuel economy?

A4: You should check your tire pressure at least once a month, and ideally before any long trips. Temperature changes can also affect tire pressure (about 1 PSI for every 10-degree Fahrenheit change), so more frequent checks might be beneficial during seasonal shifts. Proper tire inflation can improve gas mileage by up to 3.3%.
