Frequently Asked Questions
What's the difference between MPG and L/100km?
MPG (miles per gallon) measures how many miles you can travel on one gallon of fuel. L/100km (liters per 100 kilometers) measures how many liters of fuel you need to travel 100 kilometers. Lower L/100km means better fuel efficiency.
Which countries use which units?
MPG is primarily used in the United States and some other countries. L/100km is used in most European countries, Canada, Australia, and many other parts of the world. The conversion helps compare fuel efficiency globally.
What's considered good fuel economy?
For MPG: 40+ is excellent, 30-39 is good, 20-29 is average, below 20 is poor. For L/100km: below 6 is excellent, 6-8 is good, 8-12 is average, above 12 is poor.
How can I improve my fuel economy?
Maintain proper tire pressure, drive smoothly, avoid excessive idling, keep your vehicle well-maintained, remove unnecessary weight, and use cruise control on highways when possible.
Does fuel economy vary by vehicle type?
Yes, fuel economy varies significantly by vehicle type. Electric vehicles have the best efficiency, followed by hybrids, then fuel-efficient gasoline cars, with larger vehicles and trucks typically having lower fuel economy.
