Planning a road trip or commuting to a new job? Knowing your fuel costs helps you budget accurately and choose the most efficient route.
The Fuel Cost Formula
Fuel Cost = (Distance ÷ Fuel Efficiency) × Fuel Price
Where:
- Distance: Total trip distance (miles or km)
- Fuel Efficiency: Your vehicle's MPG or L/100km
- Fuel Price: Cost per gallon or liter
Example: 500-Mile Trip
- Distance: 500 miles
- Fuel efficiency: 25 MPG
- Gas price: $3.50/gallon
- Gallons needed: 500 ÷ 25 = 20 gallons
- Total fuel cost: 20 × $3.50 = $70.00
Fuel Efficiency Comparison
| Vehicle Type | MPG (City) | MPG (Highway) | Annual Fuel Cost |
|---|---|---|---|
| Compact car | 30 | 40 | $1,200 |
| SUV | 20 | 27 | $1,800 |
| Truck | 15 | 21 | $2,400 |
| Hybrid | 45 | 50 | $800 |
| EV (eMPG) | 100+ | 90 | $500 (electricity) |
Tips to Reduce Fuel Costs
1. Drive smoothly — Avoid rapid acceleration and hard braking
2. Check tire pressure — Under-inflated tires reduce MPG by up to 3%
3. Use cruise control — Maintains consistent speed on highways
4. Reduce weight — Remove unnecessary items from your trunk
5. Avoid idling — Turn off the engine if stopped for more than a minute
6. Use apps — Apps like GasBuddy find the cheapest local gas prices
CO2 Emissions Calculator
Burning one gallon of gasoline produces about 8.89 kg of CO2. For our 500-mile trip:
- 20 gallons × 8.89 kg = 177.8 kg CO2
