Adding Cars to calculate Fuel consumption

I like OpenRouteService and would like to contribute to it.
It is possible to add Cars to the Database for the Fuel Consumption?
At the moment, there are few Cars and many with partly false fuel Consumption.

Thank you for the Answers,

the fuel consumption is done by the openfuelservice, but the last update was about 2 years ago.
We currently don’t have the resources to work on it.
But if you would like to take a go at it feel free to make pull requests to
