## Using the car-cost

The car-cost is an optional feature that focus on your cars spend and consumption of fuel.

In order to be able to see something in the car-cost report window, the following step must be done:

### 1. Create some car categories

Let's say you have 2 cars:
- you create a category called 'Car' - you then create 2 subcategories that will be your cars: Peugeot 106 Sport, Peugeot 206, or whatever

Optionally you can set the default car to be initialized into the car-cost report window from the wallet dialog.

### 2. Fill in the transactions with necessary data's

First, set the corresponding category field for every of your spent for a car (refuel, repair,...)

Fill in additional data's in the description at every of your refuel:

- [d=] meter: is the distance the meter indicate at the refuel time
- [v=] fuel: is the volume of fuel you filling into the car tank

Example:

- '(d=92458 v=15.41)'
- 'd=92458, v=15.41'
- 'd=92458 v=15.41'

### 3. watch the results in the car-cost report
