Efficiency Analysis

Example Calculation

Highway Trip Example

Trip: Weekend road trip

Distance traveled: 300 miles

Fuel used: 10 US gallons

Fuel price: $3.50 per gallon

Results

Fuel Mileage: 300 miles ÷ 10 gallons = 30 MPG

Trip Cost: 10 gallons × $3.50 = $35.00

Cost per mile: $35.00 ÷ 300 miles = $0.117 per mile

Understanding Fuel Mileage

What is Fuel Mileage?

Fuel mileage, also known as fuel economy, is a measure of how efficiently a vehicle uses fuel. It represents the distance a vehicle can travel on a specific amount of fuel, typically expressed as miles per gallon (MPG) or kilometers per liter (km/L).

Why Track Fuel Mileage?

  • Monitor vehicle performance and maintenance needs
  • Calculate trip costs and fuel budgeting
  • Compare different vehicles or fuel types
  • Track environmental impact and emissions

Calculation Methods

Fuel Mileage = Distance ÷ Fuel Used

Fuel Consumption = 1 ÷ Fuel Mileage

Common Units

  • US MPG: Miles per US gallon (most common in USA)
  • UK MPG: Miles per Imperial gallon (used in UK)
  • km/L: Kilometers per liter (metric system)
  • L/100km: Liters per 100 kilometers (fuel consumption)

Tip: Track mileage over several fill-ups for more accurate averages.
