1. What is Gas Mileage?

Gas mileage (MPG - miles per gallon) measures how many miles a vehicle can travel using one gallon of fuel. It's a key indicator of a vehicle's fuel efficiency and helps compare the efficiency of different vehicles.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Miles Driven — Total distance traveled between fill-ups
• Gallons Used — Amount of fuel consumed

Explanation: The calculation divides the distance traveled by the amount of fuel used to determine how many miles the vehicle can travel per gallon of fuel.

3. Importance of Calculating MPG

Details: Tracking your gas mileage helps you monitor your vehicle's performance, identify potential mechanical issues early, and calculate fuel costs for trips. It's also useful for comparing fuel efficiency between different vehicles or driving conditions.

4. Using the Calculator

Tips: For accurate results, reset your trip odometer when you fill up your tank, 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 gas mileage?
A: This varies by vehicle type. Generally, 25+ MPG is good for most cars, while SUVs/trucks might get 15-20 MPG. Hybrids and electric vehicles get significantly higher equivalent MPG.

Q2: Why does my MPG vary?
A: Many factors affect MPG including driving habits, traffic conditions, vehicle maintenance, weather, and cargo weight.

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

Q4: Should I calculate MPG over multiple fill-ups?
A: Yes, calculating over several tanks gives a more accurate average as single-tank calculations can be affected by driving conditions.

Q5: Does the calculator work for kilometers and liters?
A: This calculator uses miles and gallons. For km/L, you would divide kilometers by liters instead.
