# How to calculate the gas mileage of my car

**Fuel consumption** is one of the aspects that drivers worry about the most. And, if we want to drive economically to save some money in these times of crisis, we need to know what our average gasoline consumption is. But, do you know how average fuel consumption is calculated? If you do not completely know the method to follow and you want to know **how to calculate the gasoline consumption of your car**, in this article we give you the keys to do it.

#### one

To have control over what you spend on fuel and improve its efficiency, you need an easy and quick method to calculate it. In this way, you will know your **average consumption** and you can try to save a bit on gasoline. Regardless of whether your car is diesel or gasoline, the calculation method is the same for both.

The first thing you should do is **fill your** fuel tank with fuel and set the **km to 0 counter** . To do this, look at the control panel. Normally the odometer is located next to the speed indicator. You will see that two numbers appear, the one above is the number of total kilometers that you have traveled with your car, and the one below is the one that you have to change and set to 0. In general, below this number is a button that you must press to do it. Then, write down the **number of total liters** you have refilled when filling the deposit.

**Exhaust the fuel** of your car until you leave it in reserve. When you reach this point, in order to calculate your car's gas mileage, **write down the number of kilometers traveled** . This way you will have the distance traveled with an entire deposit.

Now you have everything you need to calculate your car's fuel consumption, all you have to do is a **simple rule of three** . We use this formula because the only way to know what we consume is by calculating the consumption made at 100 km. So, if your car has a capacity of 40 liters and you traveled a distance of 500 km, for example, what you have to ask yourself is how many liters have I spent in 100 km? In this way, divide 40 by 500 (40: 500 = 0.08) and multiply the result by 100 (0.08x100 = 8). The result of the operation is 8 km / l. **The result will be the average fuel consumption of your car** .

If your car only counts the total kilometers traveled from the first day of life of the vehicle, and you do not have the possibility to put the counter to 0, there is **another way to calculate the consumption** . Fill the tank, write down the number of liters and the number of kilometers traveled so far.

#### 6

When you have used up all the fuel, **record the number of kilometers** traveled again. Now, to know the exact distance you made with that deposit, **subtract the two numbers** . So, if when you refilled the kilometer counter it was 70, 000 and when you exhausted the 70, 500 deposit, subtract the numbers and you will get that the kilometers traveled have been 500. Now, make the rule of three of step 4 and you will have the average gas consumption of your car.
