Why do some car exhausts drip fluid? - Ymmel

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?

It is just water. When the engine starts the cold exhaust heats up creating condensation which drips off as the exhaust fumes are expelled.

It “can” be oil, but you’d need to be pretty unlucky, and need a new engine.

And then it wouldnt “just” be oil, it would be belching out smoke too.
