Formula
Fuel Needed = Distance / Fuel Efficiency (MPG or L/100km). Cost = Fuel Needed x Price per Unit. Cost per mile = Price / MPG.
Example Calculations
Road Trip
Input: Distance: 500 miles, 25 MPG, $3.50/gallon
Result: Fuel cost: $70.00, 20 gallons needed
Daily Commute
Input: 30 miles/day, 30 MPG, $3.25/gallon, 22 days
Result: Monthly cost: $71.50
Compare Vehicles
Input: 200 miles: Car A (25mpg) vs Car B (35mpg), $3.50/gal
Result: Car A: $28.00, Car B: $20.00, Save $8.00

Peak efficiency between 45-65 mph. Above 65, drag increases significantly reducing fuel economy.
Compare fuel costs between vehicles?
Cost per mile = price / MPG. 20 mpg at $3.50/gal = $0.175/mile vs 35 mpg = $0.10/mile.
Factors affecting fuel economy?
Driving habits, traffic, maintenance, tire pressure, AC use, cargo weight, and weather.
Cruise control and efficiency?
Yes, improves economy on flat highways by maintaining constant speed. On hills, adaptive may be better.
