Fuel Saving Tips
- Maintain proper tire pressure for better fuel efficiency
- Avoid aggressive driving (rapid acceleration and braking)
- Reduce vehicle weight by removing unnecessary items
- Use cruise control on highways to maintain constant speed
- Regular maintenance improves engine efficiency
Understanding Fuel Consumption
Fuel consumption measures how much fuel your vehicle uses to travel a certain distance. It’s typically expressed as liters per 100 kilometers (L/100km) in metric countries or miles per gallon (mpg) in imperial countries.
Knowing your vehicle’s fuel consumption helps you estimate fuel costs, plan trips more effectively, and monitor your vehicle’s performance over time. Changes in fuel consumption can indicate maintenance issues.
Benefits of Tracking Fuel Consumption
Cost Management
Better predict and manage your fuel expenses
Vehicle Health
Identify potential mechanical issues early
Environmental Impact
Understand and reduce your carbon footprint
Trip Planning
Accurately estimate fuel needs for journeys
Factors That Affect Fuel Consumption
Several factors influence your vehicle’s fuel efficiency:
- Driving Habits: Aggressive acceleration and braking reduce efficiency
- Road Conditions: Hilly terrain and rough roads increase consumption
- Weather: Cold weather and strong headwinds reduce efficiency
- Vehicle Maintenance: Poorly maintained engines use more fuel
- Vehicle Load: Extra weight increases fuel consumption

Fuel Efficiency Standards
Fuel efficiency varies significantly by vehicle type and size:
Small Cars
Typically 5.0-7.0 L/100km (40-47 mpg)
Midsize Cars
Typically 7.0-9.0 L/100km (31-40 mpg)
SUVs
Typically 8.0-12.0 L/100km (24-35 mpg)
Trucks
Typically 10.0-15.0+ L/100km (16-28 mpg)
Frequently Asked Questions
This calculator provides accurate results based on the data you input. For the most precise measurement, fill your tank completely before your trip, record the distance traveled, then fill up again and note how much fuel was needed. The accuracy depends on the precision of your measurements.
L/100km (liters per 100 kilometers) is a metric measurement that shows how many liters of fuel are needed to travel 100 km. MPG (miles per gallon) is an imperial measurement that shows how many miles can be traveled on one gallon of fuel. Lower L/100km values indicate better efficiency, while higher MPG values indicate better efficiency.
Sudden increases in fuel consumption can indicate various issues: under-inflated tires, need for an oil change, dirty air filter, misaligned wheels, brake drag, or engine problems. Weather changes, different driving routes, or carrying extra weight can also affect consumption.
You can improve fuel efficiency by: maintaining proper tire pressure, performing regular maintenance, avoiding aggressive driving, reducing vehicle weight, using cruise control on highways, avoiding excessive idling, and planning efficient routes that avoid heavy traffic.
Yes, using air conditioning can increase fuel consumption by 5-20% depending on the vehicle and conditions. At lower speeds, opening windows may be more efficient, but at highway speeds, the drag from open windows can be less efficient than using AC. Modern vehicles are designed to minimize this impact.
