Gas Mileage Tips
- For the most accurate results, fill your tank completely each time and record the exact amount of fuel added.
- Reset your trip odometer at each fill-up for easier distance calculation.
- Driving at moderate speeds (around 55-65 mph) typically offers the best fuel economy for most vehicles.
- Maintain proper tire pressure to improve fuel economy by up to 3%.
- Remove excess weight from your vehicle to improve mileage.
- Regular maintenance, particularly air filter replacement, can improve fuel efficiency.
- Track your fuel economy regularly to detect any issues early-a sudden drop in MPG could indicate a mechanical problem.
