Frequently Asked Questions
How do I improve fuel economy?
Keep tires properly inflated, drive 55-65 MPH, avoid rapid acceleration, remove excess weight, and use cruise control on highways.
What is the difference between MPG and L/100km?
MPG (miles per gallon) is used in the US. L/100km (liters per 100 kilometers) is used globally. Lower L/100km = better efficiency.
How to Use This Fuel Economy Calculator
Enter your odometer readings and fuel purchased at each fill-up. The calculator computes your actual MPG or L/100km over time and tracks fuel costs.
Formula & How It Works
MPG = Miles Driven / Gallons Used. L/100km = (Liters Used / km Driven) Γ 100. To convert: MPG = 235.215 / L/100km.
Calculation Example
Drove 350 miles on 12.5 gallons: 350/12.5 = 28 MPG. In metric: 563 km on 47.3 liters = 47.3/5.63 = 8.4 L/100km.
Expert Tips
Track over multiple fill-ups for accuracy (one tank can be misleading). Highway driving gives better MPG than city. Maintain proper tire pressure β underinflated tires can reduce MPG by 3%.
