How to Use the Fuel Consumption Calculator
Choose Calculation Mode
Select what you want to calculate: Find Consumption (from distance & fuel used), Find Distance (from consumption & fuel used), or Find Fuel Used (from distance & consumption).
Select Unit System
Choose between metric (L/100km, kilometers) or imperial (MPG, miles) units based on your location and vehicle specifications.
Enter Known Values
Input the values you know. For example, if calculating consumption, enter your trip distance and fuel used. Add fuel price for cost analysis.
Review Efficiency Rating
Analyze your vehicle's fuel efficiency rating from excellent to very poor, helping you understand your car's performance compared to standards.
Check Environmental Impact
View CO₂ emissions data to understand your vehicle's environmental footprint and make informed decisions about driving habits.
Track & Export Data

Expert Fuel Efficiency & Cost Saving Tips
Maintain steady speeds: driving at consistent 55-65 mph improves fuel efficiency by 10-40% compared to aggressive acceleration and braking
Regular maintenance: proper tire pressure, clean air filters, and timely oil changes can improve fuel economy by 5-15% and extend engine life
Route planning: combine errands into single trips, use GPS for optimal routes, and avoid peak traffic to reduce fuel consumption by 10-25%
Driving technique: gradual acceleration, anticipating traffic flow, and using cruise control on highways can improve efficiency by 15-30%
Vehicle loading: remove excess weight (100 lbs = 1-2% efficiency loss), use roof racks sparingly, and keep windows closed at highway speeds
Engine warm-up: modern cars need minimal warm-up time; extended idling wastes fuel and increases emissions without benefit
Fuel quality: use recommended octane rating for your vehicle; higher octane doesn't improve efficiency unless specifically required by manufacturer
Trip optimization: cold starts are less efficient; plan longer trips when possible and consider carpooling or public transport for short distances
