The fuel is burnt.It's the harvested and useful Btu's which are the issue.
There's a lot of waste heat leaving the engine via the cooling system and exhaust gas.
A Toyota Prius with an adiabatic engine would only get about 130 mpg on the highway.
I would take your friend to task for suggesting that they're experiencing 430-mpg.
The old vapor carburetors claimed only 150-mpg.And that was at a steady 35-mph.(that's all the car would do.35-mph).
