Improve Highlander Gas Mileage: Proven Tips

If you own a Ford Highlander, achieving better fuel efficiency shouldn’t be out of reach. With rising fuel costs, improving gas mileage is both practical and cost-saving. This guide reveals actionable, science-backed strategies to maximize every gallon and extend your driving range.

Why Highlander Fuel Efficiency Matters

The Ford Highlander is a popular midsize SUV known for reliability and utility—but its fuel economy often falls short of ideal, especially in city driving. According to 2024 EPA estimates, the 2023–2024 Highlander averages 21–24 MPG combined, depending on trim and driving conditions. Even small improvements can reduce fuel bills significantly over time. Beyond savings, better mileage supports environmental goals by lowering CO2 emissions, aligning with growing eco-consciousness among drivers.

Key Factors Affecting Highlander Fuel Economy

Several variables influence your Highlander’s gas mileage. Understanding them helps target the right fixes:

• Driving habits: Aggressive acceleration and frequent braking spike fuel consumption.
• Vehicle maintenance: Underinflated tires, dirty air filters, and outdated spark plugs reduce efficiency.
• Tire pressure and type: Optimal inflation and low-rolling-resistance tires improve fuel economy.
• Load and weight: Extra cargo or roof racks increase drag and fuel use.

Proven Methods to Boost Gas Mileage

Maintain Optimal Tire Pressure and Use Low-Roll-Resistance Tires

Proper tire inflation is one of the simplest yet most impactful changes. Underinflated tires increase rolling resistance by up to 3%, lowering MPG. Check pressure monthly and adjust to manufacturer specs—typically 30–35 PSI. For longer-term gains, consider low-rolling-resistance tires designed for fuel-efficient SUVs. These specialized tires reduce friction without sacrificing grip, saving 3–5% in fuel over time.

Optimize Driving Habits for Maximum Efficiency

Your driving style directly impacts fuel use. Smooth acceleration, steady speeds, and anticipating traffic reduce unnecessary fuel burn. Avoid rapid starts and hard braking—use cruise control on highways when possible. In stop-and-go traffic, maintaining a consistent 5–10 mph gap between vehicles minimizes stop-and-go energy waste. Studies show aggressive driving lowers fuel efficiency by 15–30%, making calm, predictable driving a key habit.

Service and Maintain Your Highlander Regularly

Regular maintenance ensures your engine runs at peak performance. Replace air filters every 15,000–30,000 miles to improve combustion efficiency. Rotate and balance tires every 5,000–7,500 miles to prevent uneven wear and maintain steady handling. Timing belt inspections every 90,000–100,000 miles prevent costly engine damage that could impair efficiency. Following the manufacturer’s service schedule not only protects reliability but also keeps fuel economy strong.

Reduce Vehicle Weight and Aerodynamic Drag

Every pound and air resistance factor matters. Remove unnecessary items from the trunk and back seats—extra weight forces the engine to work harder. Use roof racks only when needed, as they increase drag and reduce MPG. Installing small aerodynamic upgrades like rear spoilers or streamlined side mirrors can improve airflow and save up to 2% in city and highway driving. Choose lightweight, durable accessories that enhance efficiency without compromising safety.

Real-World Impact: Case Study and Results

A 2024 review by Consumer Reports tested a 2023 Highlander with upgraded tire pressure, optimized driving, and routine maintenance. The result: fuel economy improved from 22.1 MPG to 25.4 MPG combined—an average gain of 15.5% over 6 months. Drivers reported noticeable savings on weekly commutes and road trips, proving small adjustments deliver meaningful returns.

Conclusion and Call to Action

Boosting your Highlander’s gas mileage is achievable through simple, consistent actions—from tire care to mindful driving. Start today by checking tire pressure, adopting smoother driving habits, and scheduling a maintenance check. These steps not only lower fuel costs but also extend your vehicle’s life and reduce environmental impact. Take control of your driving efficiency—your wallet and the planet will thank you.
