How to Maximize Your Car’s Fuel Efficiency
Even with a fuel-efficient car, driving habits and maintenance can significantly impact mileage. Here are some tips to optimize fuel efficiency:
1. Maintain Proper Tire Pressure
Under-inflated tires increase rolling resistance, reducing MPG.
2. Drive Smoothly
Avoid rapid acceleration and sudden braking to improve efficiency.
3. Use Cruise Control
Helps maintain a steady speed and reduces fuel consumption on highways.
4. Reduce Excess Weight
Unnecessary weight in your car forces the engine to work harder.
5. Keep Up With Regular Maintenance
Oil changes, air filter replacements, and engine tune-ups ensure optimal performance.
6. Avoid Idling
Turn off your engine if you expect to be stationary for more than a minute.
