Fuel Efficiency Analysis
Factors Affecting Fuel Efficiency
Fuel efficiency depends on several factors:
- Driving Habits: Aggressive acceleration and braking reduce efficiency by up to 33%
- Vehicle Maintenance: Regular tune-ups, proper tire inflation, and clean air filters improve efficiency
- Speed: Driving at high speeds uses significantly more fuel
- Weight: Extra weight reduces fuel economy by 1-2% for every 100 lbs
- Weather: Cold weather can reduce efficiency by 12-22%
- Traffic Conditions: Stop-and-go traffic significantly reduces efficiency
Tips to Improve Efficiency
Improve your fuel efficiency with these tips:
- Drive smoothly - accelerate gradually and brake gently
- Maintain proper tire pressure (check monthly)
- Remove excess weight from your vehicle
- Use cruise control on highways
- Avoid idling for more than 30 seconds
- Plan trips to combine errands
- Use the recommended grade of motor oil
- Keep your engine properly tuned
Efficiency Calculation Formulas
How Efficiency is Calculated
The efficiency calculation depends on the units selected:
- Miles per Gallon (MPG): Distance (miles) / Fuel (gallons)
- Kilometers per Liter (KM/L): Distance (km) / Fuel (liters)
- Kilometers per Gallon (KM/Gal): Distance (km) / Fuel (gallons)
- Liters per 100 Kilometers (L/100KM): (Fuel (liters) × 100) / Distance (km)
Cost Calculations
Total fuel cost is simply the sum of all trip costs. Cost per unit distance is calculated as:
- Cost per Mile/Kilometer: Total Cost / Total Distance
