Frequently Asked Questions
How do I calculate fuel economy?
Miles Driven ÷ Gallons Used = MPG. For metric: Kilometers ÷ Liters = KM/L.
What is good fuel economy?
Depends on vehicle type. Cars: 25-35 MPG good, SUVs: 20-25 MPG good, Trucks: 18-22 MPG good.
Why does my MPG vary?
Driving habits, road conditions, load, fuel type, and maintenance all affect economy. Highway driving improves MPG vs. city driving.
How can I improve fuel economy?
Keep tires inflated, reduce aggressive acceleration, maintain steady speeds, reduce weight, and keep up maintenance.
