1. What is Fuel Mileage?

Fuel mileage (also called fuel economy) measures how far a vehicle can travel on a given amount of fuel. It's typically expressed in miles per gallon (mpg) and is a key indicator of a vehicle's efficiency.

2. How Does the Calculator Work?

The calculator uses the basic mileage formula:

Where:

• Distance Traveled — Miles driven between fuel fill-ups
• Fuel Used — Gallons consumed to travel that distance

Explanation: This simple division gives the average miles per gallon (mpg) for the measured distance.

3. Importance of Mileage Calculation

Details: Tracking fuel mileage helps monitor vehicle performance, identify maintenance needs, and calculate fuel costs for trips. It's also useful for comparing vehicle efficiency.

4. Using the Calculator

Tips: For accurate results, reset your trip odometer when filling up, then note the miles driven and gallons needed at the next fill-up. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's considered good fuel mileage?
A: This varies by vehicle type. Generally, 25+ mpg is good for cars, while SUVs/trucks may get 15-20 mpg. Hybrids/electric vehicles get significantly higher equivalent mileage.

Q2: Why does my mileage vary?
A: Factors include driving habits, traffic conditions, vehicle maintenance, cargo load, and weather. Highway driving typically gives better mileage than city driving.

Q3: How can I improve my fuel mileage?
A: Regular maintenance, proper tire inflation, reducing excess weight, and moderate acceleration/braking can all help improve mileage.

Q4: Should I calculate mileage over multiple tanks?
A: For the most accurate long-term average, track mileage over several fill-ups and calculate the overall average.

Q5: Does the calculator work for kilometers and liters?
A: The formula works with any units, but this calculator specifically uses miles and gallons. For km/liter, you would need to input those units instead.
