1. What is Miles Per Gallon (MPG)?

MPG (Miles Per Gallon) is a measurement of a vehicle's fuel efficiency, showing how many miles the vehicle can travel using one gallon of fuel. It's a standard metric for comparing fuel economy between different vehicles.

2. How Does the Calculator Work?

The calculator uses the simple MPG formula:

Where:

• Miles Driven — Total distance traveled (miles)
• Gallons Used — Total fuel consumed (gallons)

Explanation: The calculation divides the total miles driven by the total gallons of fuel used during that period.

3. Importance of MPG Calculation

Details: Knowing your vehicle's MPG helps estimate fuel costs for trips, compare fuel efficiency between vehicles, and identify potential mechanical issues if MPG drops suddenly.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's considered good MPG?
A: This varies by vehicle type. Generally, 25+ MPG is good for city driving, while 30+ is good for highway. Electric vehicles use different metrics (MPGe).

Q2: Why does my actual MPG differ from the manufacturer's rating?
A: Manufacturer tests use controlled conditions. Real-world factors like driving style, traffic, weather, and vehicle maintenance affect actual MPG.

Q3: How can I improve my vehicle's MPG?
A: Regular maintenance, proper tire inflation, reducing weight, avoiding aggressive driving, and using cruise control on highways can help improve MPG.

Q4: Does MPG change with vehicle age?
A: Yes, as engines wear and components degrade, fuel efficiency typically decreases slightly over time.

Q5: Is MPG the same as fuel economy?
A: Essentially yes, though some countries use liters per 100 kilometers (L/100km) instead. Higher MPG means better fuel economy.
