1. What is Gas Mileage?

Gas mileage (also called fuel economy) measures how far a vehicle can travel on a specific amount of fuel. It's typically expressed in miles per gallon (mpg) in the United States.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Distance Traveled — Miles driven during the trip
• Gas Used — Gallons of fuel consumed during the trip

Explanation: This calculation gives you the average miles your vehicle traveled per gallon of fuel used.

3. Importance of Tracking Mileage

Details: Monitoring your gas mileage helps identify changes in vehicle performance, plan fuel costs for trips, and assess the efficiency of your driving habits or vehicle maintenance.

4. Using the Calculator

Tips: For accurate results, fill your tank completely before your trip and again after to measure exact gas used. Record your odometer readings at both fill-ups for precise distance measurement.

5. Frequently Asked Questions (FAQ)

Q1: What's considered good gas mileage?
A: This varies by vehicle type. Generally, 25+ mpg is good for most cars, while SUVs/trucks may get 15-20 mpg. Hybrids and electrics have higher equivalents.

Q2: Why did my mileage suddenly drop?
A: Possible causes include poor maintenance, underinflated tires, carrying heavy loads, or changes in driving conditions (more city vs highway driving).

Q3: How can I improve my gas mileage?
A: Regular maintenance, proper tire inflation, reducing excess weight, and smoother driving habits can all improve mileage.

Q4: Should I use trip computer or manual calculation?
A: Manual calculations (like this calculator) are often more accurate than vehicle trip computers, especially over multiple fill-ups.

Q5: Does AC use affect mileage significantly?
A: AC can reduce mileage by 1-4 mpg in most vehicles, especially at lower speeds. At highway speeds, open windows create drag that may offset AC usage.
