And what is it? Always assumed it was just water but now I’m pretty sure it’s not. Also do all cars do this?

    No, if your car was built in the last 50 years it probably has a catalytic converter, which will burn off any fuel that hasn’t combusted before it gets out of the exhaust. And even so, once you get to the point where you’re having fuel flow out the exhaust it would be flooded to the point well beyond hydro-lock and wouldn’t be running at all.
