Understanding Fuel Consumption
Fuel consumption is a measurement of how much fuel a vehicle uses to travel a specific distance. Unlike "fuel economy" (how far you can go on a set amount of fuel), consumption focuses on the volume of fuel required for the journey. This is typically expressed in Liters per 100 Kilometers (L/100km) in metric systems or Miles per Gallon (MPG) in imperial systems.
How to Calculate L/100km
To calculate your vehicle's fuel consumption manually, follow this simple formula:
For example, if you drove 600 kilometers and used 45 liters of fuel: (45 / 600) * 100 = 7.5 L/100km.
Factors That Affect Fuel Efficiency
- Driving Habits: Rapid acceleration and heavy braking significantly increase fuel usage.
- Vehicle Maintenance: Under-inflated tires, dirty air filters, and old spark plugs can reduce efficiency by up to 10%.
- Weight and Aerodynamics: Carrying unnecessary weight or using roof racks creates drag and increases consumption.
- Idling: Leaving the engine running while stationary consumes fuel without moving the vehicle.
Practical Example
Imagine you are planning a 1,200 km road trip. Your car averages 8.0 L/100km and fuel costs $1.50 per liter. Using this calculator, you can determine that you will need 96 liters of fuel, costing you a total of $144 for the trip. Knowing these figures helps in budgeting and comparing different travel options.
