Understanding Fuel Costs
Fuel Efficiency Units
MPG (Miles per Gallon)
Common in the US. Higher numbers mean better efficiency.
L/100km (Liters per 100km)
Common in Europe. Lower numbers mean better efficiency.
KM/L (Kilometers per Liter)
Common in Asia. Higher numbers mean better efficiency.
Factors Affecting Fuel Costs
Vehicle Factors
- • Engine size and type
- • Vehicle weight and aerodynamics
- • Transmission type
- • Maintenance condition
- • Tire pressure and condition
Driving Factors
- • Driving speed and style
- • Traffic conditions
- • Route terrain (hills, city vs highway)
- • Weather conditions
- • Air conditioning usage
Cost Optimization Tips

Example Calculations
Road Trip Example
Vehicle: 25 MPG efficiency
Fuel Price: $3.50 per gallon
Calculation: (1000 miles ÷ 25 MPG) × $3.50 = $140
Daily Commute Example
Vehicle: 30 MPG efficiency
Fuel Price: $3.25 per gallon
Weekly Cost: (150 miles ÷ 30 MPG) × $3.25 = $16.25
Frequently Asked Questions
How accurate are these fuel cost calculations?
The calculations are based on the inputs you provide and use standard formulas. Actual costs may vary due to driving conditions, vehicle maintenance, weather, and driving habits. Use these as estimates for planning.
Where can I find my vehicle's fuel efficiency rating?
Check your vehicle's owner manual, the EPA fuel economy sticker, or websites like fueleconomy.gov. Your actual efficiency may differ from EPA ratings based on driving conditions and habits.
Should I use city or highway MPG ratings?
Use the rating that best matches your driving conditions. For mixed driving, the combined MPG rating is most appropriate. Highway driving typically achieves better efficiency than city driving.
How do I convert between different efficiency units?
The calculator handles conversions automatically. Generally: higher MPG = better efficiency, lower L/100km = better efficiency, higher KM/L = better efficiency.
