How to Use the Fuel Consumption Calculator

1

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).

2

Select Unit System

Choose between metric (L/100km, kilometers) or imperial (MPG, miles) units based on your location and vehicle specifications.

3

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.

4

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.

5

Check Environmental Impact

View CO₂ emissions data to understand your vehicle's environmental footprint and make informed decisions about driving habits.

6

Track & Export Data

Save calculations to history for fuel tracking, export data for expense reports, and share results for fleet management or cost analysis.

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
