How do I calculate my gas mileage?
Divide the miles driven by the gallons of gas used. For example, if you drove 300 miles and used 10 gallons, your gas mileage is 30 MPG (miles per gallon).
What is good gas mileage?
Good gas mileage depends on vehicle type. Compact cars average 30-40 MPG, midsize sedans 25-35 MPG, SUVs 20-30 MPG, and trucks 15-25 MPG. Hybrids can exceed 50 MPG.
How can I improve my gas mileage?
Maintain proper tire pressure, avoid aggressive driving, remove excess weight, use cruise control on highways, keep up with maintenance, and avoid excessive idling.
What is the difference between MPG and L/100km?
MPG (miles per gallon) measures distance per fuel unit - higher is better. L/100km (liters per 100 kilometers) measures fuel per distance - lower is better. They are inverse measurements.
Why is my actual mileage different from EPA estimates?
EPA estimates are based on standardized tests. Real-world mileage varies based on driving habits, weather, terrain, vehicle condition, and load. City driving typically yields lower MPG than highway.
