Calculate MPG, fuel cost per trip, annual fuel expenses, and compare vehicle efficiency.
| Vehicle Type | Avg Efficiency | Cost/100 miles | Annual Cost* |
|---|
* Based on 12,000 miles/year and $3.50/gallon fuel
Fuel consumption is a measure of how efficiently a vehicle uses fuel. It's typically expressed as miles per gallon (MPG) in the US or liters per 100 kilometers (L/100km) in most other countries.
1. Maintain proper tire pressure: Underinflated tires can reduce fuel efficiency by up to 3%
2. Reduce idling: Idling for more than 10 seconds uses more fuel than restarting your engine
3. Drive smoothly: Aggressive acceleration and braking can reduce fuel efficiency by 15-30%
4. Remove excess weight: An extra 100 pounds can reduce MPG by about 1%
5. Use cruise control: Maintaining a constant speed improves fuel efficiency
Factors that affect fuel consumption:
Understanding your vehicle's fuel consumption can help you save money, reduce environmental impact, and make informed decisions about vehicle purchases and usage patterns.
| Vehicle Type | Good MPG | Average MPG | Poor MPG |
|---|---|---|---|
| Compact Car | 30+ | 25-30 | < 25 |
| Sedan | 28+ | 22-28 | < 22 |
| SUV | 25+ | 20-25 | < 20 |
| Truck | 22+ | 17-22 | < 17 |
| Hybrid | 45+ | 40-45 | < 40 |
• MPG to L/100km: 235 / MPG
• L/100km to MPG: 235 / L/100km
• 1 US gallon = 3.785 liters
• 1 mile = 1.609 kilometers
• 1 gallon of gasoline produces about 8.8 kg of CO2
• 1 liter of gasoline produces about 2.3 kg of CO2
• The average car produces about 4.6 metric tons of CO2 per year
