Parameters:

  • Original MPG:
  • Improved MPG (with Monte Tuning): (8%improvement from MPG)
  • Fuel Price: USD per gallon
  • Miles Driven: 15,000 miles

Updated Calculations:

  1. Fuel Needed Without Monte Tuning:
    • Gallons Needed = Miles Driven / Original MPG
    • Gallons Needed = 15,000 / = Gallons
  2. Fuel Cost Without Monte Tuning:
    • Total Fuel Cost = Gallons Needed × Fuel Price
    • Total Fuel Cost = × = USD
  3. Fuel Needed With Monte Tuning:
    • Gallons Needed = Miles Driven / Improved MPG
    • Gallons Needed = 15,000 / Gallons
  4. Fuel Cost with Monte Tuning :
