What Is Fuel Economy
Fuel economy measures how efficiently your vehicle uses fuel, typically expressed as the distance traveled per unit of fuel consumed. Different regions use various measurement systems, but all measure the relationship between distance traveled and fuel consumed. Understanding fuel economy helps manage costs and make informed decisions about vehicle selection and driving habits.
Common Fuel Economy Measurements
Miles Per Gallon (MPG)- Standard in the United States
- Higher numbers indicate better fuel efficiency
- Calculated as: Distance (miles) ÷ Fuel Used (gallons)
- Standard in most countries using the metric system
- Lower numbers indicate better fuel efficiency
- Calculated as: (Fuel Used (liters) × 100) ÷ Distance (kilometers)
- Used in some countries
- Higher numbers indicate better fuel efficiency
- Calculated as: Distance (kilometers) ÷ Fuel Used (liters)
Key Points
- Measurement Systems: MPG (US), L/100km (metric), and km/L are different ways to express the same concept
- Higher MPG/Lower L/100km: Better fuel economy means lower fuel costs and reduced environmental impact
- Multiple Factors: Driving habits, vehicle maintenance, road conditions, and vehicle type all affect fuel economy
- Cost Impact: Improving fuel economy by even 10% can save hundreds of dollars annually
- Environmental Benefit: Better fuel economy reduces carbon emissions and environmental impact

Improving Your Fuel Economy
Maintenance Tips
Regular Service- Change air filters regularly
- Maintain proper tire pressure
- Use recommended motor oil
- Keep up with scheduled maintenance
- Remove excess weight
- Use cruise control on highways
- Plan efficient routes
- Combine errands into single trips
Driving Techniques
Efficient Driving- Gradual acceleration and deceleration
- Maintain steady speeds
- Anticipate traffic flow
- Use air conditioning wisely
- Observe speed limits
- Use highway speeds efficiently
- Avoid excessive idling
Fuel Cost Calculations
Cost Per Mile/Kilometer
Calculate your driving costs:
- Fuel Economy ÷ Fuel Price = Cost per unit distance
- Example: 25 MPG ÷ $3.50/gallon = $0.14 per mile
Annual Fuel Costs
Estimate yearly expenses:
- Annual Miles ÷ Fuel Economy × Fuel Price = Annual Cost
- Example: 12,000 miles ÷ 25 MPG × $3.50 = $1,680
Trip Cost Planning
Budget for specific trips:
- Trip Distance ÷ Fuel Economy × Fuel Price = Trip Cost
- Add 10-15% buffer for price variations
Comparing Vehicle Efficiency
Fuel Economy Standards
Excellent Efficiency- Cars: 35+ MPG (6.7 L/100km or less)
- SUVs: 25+ MPG (9.4 L/100km or less)
- Trucks: 20+ MPG (11.8 L/100km or less)
- Cars: 25-35 MPG (6.7-9.4 L/100km)
- SUVs: 18-25 MPG (9.4-13.1 L/100km)
- Trucks: 15-20 MPG (11.8-15.7 L/100km)
Vehicle Selection Considerations
Fuel Efficiency vs. Needs- Balance efficiency with practical requirements
- Consider hybrid or electric alternatives
- Evaluate total cost of ownership

Frequently Asked Questions
Q: How do I calculate MPG (miles per gallon)?
A: Divide the number of miles driven by the gallons of fuel used. For example, if you drove 300 miles and used 10 gallons, your MPG is 300 ÷ 10 = 30 MPG.
Q: How do I convert MPG to L/100km?
A: Use the formula: L/100km = 235.214 ÷ MPG. For example, 30 MPG = 235.214 ÷ 30 = 7.84 L/100km.
Q: What's the difference between city and highway fuel economy?
A: City driving involves more stops and starts, reducing efficiency. Highway driving at steady speeds typically yields better fuel economy, often 20-30% higher than city driving.
Q: Can weather affect fuel economy?
A: Yes, cold weather, headwinds, and air conditioning use can reduce fuel economy by 10-40% depending on conditions. Cold engines are less efficient, and heating/AC systems consume additional energy.
Q: How can I improve my vehicle's fuel economy?
A: Maintain proper tire pressure, drive smoothly without rapid acceleration or braking, remove excess weight, use cruise control on highways, and keep up with regular maintenance including oil changes and air filter replacements.
Q: How accurate are fuel economy ratings from manufacturers?
A: Manufacturer ratings are estimates based on standardized tests. Real-world fuel economy typically varies by 10-20% from these ratings due to driving conditions, habits, and vehicle maintenance.
