# Fuel consumption calculation

Configure the device-side Fuel consumption calculation block in Navixy by setting fuel type, engine volume, and a multiplier for the estimate.

Sets the parameters the device uses to compute fuel consumption itself. This is separate from platform-side [fuel sensors](/docs/user/guide/devices-and-settings/vehicle-sensors/measurement-sensors.md).

## Settings

* **Fuel type**: gasoline, diesel, or LPG. Affects the built-in fuel rates the device uses to estimate consumption.
* **Engine volume**: the engine displacement in liters (for example, 2.0 for a 2-liter engine).
* **Multiplier**: a correction factor applied to the estimated result. Use 1.0 for no correction. Set it below 1.0 if the device overestimates consumption, or above 1.0 if it underestimates.

## Availability

Appears on device models that compute fuel consumption on the device side.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://navixy.com/docs/user/guide/devices-and-settings/device-specific-controls/engine-and-diagnostics/fuel-consumption-calculation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
