Tips for Improving Fuel Economy

  • Keep tires properly inflated and perform regular vehicle maintenance.
  • Drive smoothly, avoid aggressive acceleration and hard braking.
  • Reduce excess weight and remove roof racks when not in use.
  • Use cruise control on highways to maintain steady speeds.
  • Minimize engine idling and use air conditioning efficiently.
  • Plan trips to minimize cold starts and combine errands when possible.

About Gas Mileage & Fuel Cost Calculation

MPG (Miles Per Gallon) and L/100km (Liters per 100 Kilometers) are common measures of fuel efficiency. Lower L/100km or higher MPG means better fuel efficiency.

Fuel Efficiency Formula: For MPG: MPG = Distance (miles) / Fuel Used (US gallons)
For L/100km: L/100km = (Fuel Used (liters) / Distance (km)) × 100

Trip Cost: Trip Cost = Fuel Used × Fuel Price per unit
