1. What is Fuel Efficiency?

Fuel efficiency, measured in miles per gallon (MPG), indicates how far a vehicle can travel on a gallon of fuel. It's a key metric for evaluating vehicle performance, environmental impact, and operating costs.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Total Distance — Miles traveled
• Total Fuel — Gallons of fuel consumed

Explanation: This calculation provides the average fuel efficiency over a specific driving period or trip.

3. Importance of Fuel Efficiency

Details: Monitoring fuel efficiency helps drivers save money on fuel, reduce environmental impact, identify vehicle maintenance issues, and make informed decisions about vehicle usage and purchases.

4. Using the Calculator

Tips: Enter the total distance traveled in miles and the total fuel consumed in gallons. For accurate results, measure fuel consumption over a significant distance (100+ miles is recommended).

5. Frequently Asked Questions (FAQ)

Q1: What is considered good fuel efficiency?
A: This varies by vehicle type, but generally: 25+ MPG for sedans, 20+ MPG for SUVs, and 30+ MPG for hybrids is considered good.

Q2: How can I improve my vehicle's fuel efficiency?
A: Regular maintenance, proper tire inflation, reduced idling, smooth acceleration, and removing excess weight can improve MPG.

Q3: Why does my actual MPG differ from the manufacturer's rating?
A: Manufacturer tests are conducted in controlled conditions. Real-world driving with traffic, weather variations, and driving habits affect actual fuel efficiency.

Q4: How often should I calculate my fuel efficiency?
A: Tracking MPG over several tanks of fuel provides the most accurate average. Calculating every fill-up helps identify changes quickly.

Q5: Does fuel efficiency change with vehicle age?
A: Yes, as engines wear and components degrade, fuel efficiency typically decreases slightly over time without proper maintenance.
