Fuel Tools & Calculators
Free, practical tools for every driver — measure your true MPG, plan your range and fuel stops, compare vehicles and gas-versus-electric running costs, price a trip at the pump, and estimate your driving carbon footprint.
⛽ MPG Calculator
Work out your real fuel economy from the miles driven and the gallons used — miles per gallon plus the metric equivalents in L/100km and km/L
🛣️ Gas Mileage & Range Calculator
Turn your MPG and tank size into a driving range, hold back a reserve you never dip below, and see the gallons a trip needs and whether one tank covers it
📊 Fuel Economy Comparison Calculator
Compare two vehicles by MPG over a year's driving at a set fuel price — annual gallons and fuel cost for each, and the yearly saving of the more economical one
💵 Fuel Cost Calculator
Price the fuel for a trip from its distance, your MPG, and the pump price — with round-trip and repeat-trip options, plus gallons burned and cost per mile
🔌 EV vs Gas Cost Calculator
Compare the running cost of a gas car and an electric car — cost per mile from MPG and pump price versus kWh/100mi and electricity price, and the annual saving
🌍 Driving Carbon Footprint Calculator
Estimate the CO₂ from your driving with the EPA gasoline factor — annual gallons burned and the kilograms and tons of CO₂, with an optional EV comparison
