Can you add some additional tank sounds based on the fuel!

I love Factorio, and this is my first post!

I really wish the fuel type affected the sounds the tank, and maybe other vehicles make. A tank running on coal should sound clunky, like a stream engine; but a tank that runs on solid fuel should sound like an M1A1 Abrams jet turbine. Anyhow, just my little suggestion.

Keep up the fantastic work!
