Don't know if this will help in any way, but here, is possible to set some race options.
It is possible to change fuel and tyre wear amongst other stuff.
That will change the fuel rate of the entire session, meaning every car on that session will have its comsumption multiplied by that.
Like everything else on a car, he'll need to go through the .acd I guess.
For older projects I made for private use, I know for a fact that every car has a specific number that corresponds to the fuel consumption rate, then the game does the rest of the math.
He'll have to find that value and tinker with it.
