# Gas Mileage Calculator + Online Solver With Free Steps

The online Gas Mileage Calculator is a calculator that allows you to find the gas mileage of your vehicle. The Gas Mileage Calculator is a versatile tool that helps people figure out how much fuel their vehicles consume.

## What Is a Gas Mileage Calculator?

A Gas Mileage Calculator is an online calculator that allows you to determine how many miles your vehicle moves per gallon of gas.

The Gas Mileage Calculator takes in only two inputs: the distance covered and the gallons of gas consumed by the vehicle.

## How To Use a Gas Mileage Calculator?

To use the Gas Mileage Calculator, you input all the necessary information into their respective boxes and click the “Submit” button. The calculator will instantly produce the results.

The detailed step-by-step instructions on how to use the Gas Mileage Calculator are as follows:

### Step 1

Initially, we enter the miles driven by the vehicle into the Gas Mileage Calculator.

### Step 2

After entering the miles the vehicle has driven, we enter the gallons of gas the car consumes into the Gas Mileage Calculator.

### Step 3

Finally, after entering the miles driven and the vehicle’s gas consumption into the Gas Mileage Calculator, we click the “Submit” button on the calculator. The calculator quickly finds the gas mileage of the calculator.

## How Does a Gas Mileage Calculator Work?

The Gas Mileage Calculator works by taking both inputs and finding the miles driven per gallon by the vehicle. The calculator uses the following formula to calculate the gas mileage of the car:

$\text{Gas Mileage} = \frac{\text{Miles driven by the vehicle}}{\text{Gallons of gas consumed}}$

## What Is Gas Mileage?

Gas mileage is the number of miles a vehicle can travel in a particular amount of fuel. Gas mileage is also known as fuel economy. There are several ways to calculate gas mileage throughout the world.

In the United States, gas mileage is calculated in miles per gallon. Here we divide the number of miles traveled by the vehicle by the gallons of gas consumed. The following formula can represent it:

$\text{Gas Mileage (mpg)} = \frac{\text{Miles driven by the vehicle}}{\text{Gallons of gas consumed}}$

In other parts of the world, gas mileage is measured by the kilometers (km) a car travels by the liters of fuel consumed. Here the unit of measurement is km/L. The following formula can represent this:

$\text{Gas Mileage (km/L)} = \frac{\text{Kilometers driven by the vehicle}}{\text{Liters of fuel consumed}}$

A car with a high gas mileage is not only economical but also safer for the environment as well. The ideal gas mileage of a vehicle should be around 23 mpg.

## What Factors Affect Gas Mileage?

Gas mileage can be affected by several factors such as engine oil and tire air pressure. Here are some other notable factors that majorly affect your gas mileage:

### Engine Oil

You may reduce gasoline usage by changing your engine oil at regular, manufacturer-recommended intervals. Old engine oil could be the cause if you’ve observed a decrease in fuel economy and haven’t changed your engine oil recently.

Car manufacturers have improved fuel and engine oil technologies for more recent models (2013 or later), so you should only need to replace your oil every 7,000–10,000 miles.

### Air Pressure of your Tires

Tire pressure maintenance reduces friction, which reduces the need for greater engine power and fuel. The same is true of worn tires; newer tires have better tread and experience less friction, which improves fuel economy because it requires less gasoline and engine power to go the same distance.

### Using Air Conditioning

Utilizing the air conditioner can cause your engine to work harder and use more gasoline. Crack a window until the interior temperature of your automobile is equal to or lower than the outside temperature to solve this issue.

### Aggressive Driving

Aggressive driving is one of the significant factors affecting gas mileage. This is divided into three parts; driving too fast, accelerating too swiftly, and stopping too abruptly. All three of these acts result in excessive fuel usage.

### Weight

Your car’s fuel efficiency may suffer if you carry more passengers, haul a lot of cargo, or tow a trailer. This is because the additional weight puts a lot of stress on your engine.

## Increasing a Vehicle’s Gas Mileage

To increase your vehicle’s gas mileage, you can take several steps. Here are some ways how you can make your gas mileage more efficient:

You can achieve excellent gas mileage by accelerating steadily and evenly without pressing hard on the gas pedal. Driving slower, especially at speeds under 50 mph, can also significantly impact your mpg. The most fuel-efficient speed also varies between makes and models, but going beyond the speed limit can reduce fuel economy by 7–14%.

### Replacing Spark Plugs

Your 100,000-mile spark plugs are 80% worn if you have 80,000 miles on them. During the last 20,000 kilometers, misfires and incomplete combustion occur more frequently. This helps your engine to work efficiently and prevents any excessive fuel combustion.

### Replacing Oxygen Sensors

Oxygen sensors track how much oxygen is still present in the exhaust to determine the effectiveness of combustion. However, they lose quality over time, reducing your gas mileage by up to 15%. The computer turns on your “service engine soon” light when they malfunction.

### Reduce Extra Cargo

Your car’s gas mileage can drop by up to 1% when you add 100 pounds. Relative to the vehicle’s weight, the reduction is as follows: Increased weight significantly impacts smaller vehicles than larger ones.

### Checking Tire Alignment

Misaligned tires don’t roll freely; they drag. Poor alignment might result in a 10% reduction in fuel efficiency. The tires may also deteriorate more quickly.

Out-of-balance tires can result in uneven tire wear and reduced fuel efficiency. Therefore, tires should be rotated and balanced following the owner’s manual for the vehicle to enhance tire performance and fuel efficiency.

## Gas Mileage and the Climate

Gas mileage and climate are closely interrelated with each other. Cars produce toxic gases when the fuel combusts. These gases damage the ozone layer and cause pollution, causing global warming.

Fuel economic cars may help reduce pollution and smog by 50%. Cars with excellent gas mileage produce less toxic gases helping reduce environmental pollutants. Furthermore, having a good gas mileage not only enables you to save the environment but also helps you save money.

## Solved Examples

The Gas Mileage Calculator is a fantastic tool that quickly provides you with your vehicle’s gas mileage. The Gas Mileage Calculator proves to be valid for everyday use.
