# How To Calculate Fuel Consumption Rates

The fuel consumption rate of a car is a value that shows how much gasoline (diesel fuel, gas) was consumed when the car traveled a certain number of kilometers.

## Instructions

### Step 1

Recently, most cars (especially foreign cars) are equipped with on-board computers. Therefore, it is not difficult to determine the rate of fuel consumption, it is enough to look at the display of this computer, where all the information is displayed.

### Step 2

If you do not have an on-board computer, then you can determine the fuel consumption as follows: - fill the car's fuel tank completely;

- reset the counter on the speedometer to know how many kilometers you will drive;

- when gasoline runs out, divide the number of kilometers by the number of liters of fuel poured in, and you will get the fuel consumption figure

### Step 3

However, fuel consumption will not always be the same. Its value is influenced by a lot of factors. First of all, it is necessary to check the air filter and, if necessary, replace it; when the filter is used, fuel consumption increases significantly.

### Step 4

The second action that needs to be performed is to measure the content of carbon monoxide (CO) during idle at 2000 - 3000 rpm. If the level is too high, then you will need the help of specialists.

### Step 5

It should be remembered that an unadjusted car consumes about 10% more fuel. Low pressure wheels also increase fuel consumption.

### Step 6

The camber must be very precisely adjusted to save on gasoline. If the air conditioner is running in the car, the fuel consumption increases by 10%, and sometimes more, it will depend on the operating mode.

### Step 7

Remember that open windows in a car at a speed of more than 50 km / h increase consumption by 2-3%, the higher the speed and the more open the windows, the greater the consumption.

### Step 8

With frequent braking of the car and subsequent acceleration, gasoline consumption also increases. Do not brake abruptly, try to slow down smoothly.

### Step 9

When on a bump or slope, use the handbrake instead of using the clutch and accelerator pedal.

### Step 10

Correct selection of gears will also help to reduce fuel consumption, do not shift upshifts ahead of time, this will reduce acceleration time and increase fuel consumption.

### Step 11

Observe the optimal speed at which fuel consumption is minimal, usually it is 90-100 km / h.

### Step 12

Do not warm up your car for more than two minutes, unless, of course, there is a strong minus on the street. You can calculate the car's fuel consumption rates using the data provided, which should be taken into account when choosing a driving mode for a car. The technical condition of the car should also be taken into account.
