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.
