No, propane does not smell like lighter fluid. Propane in its natural state is odorless; however, a sulfur-smelling compound called ethanethiol (ethyl mercaptan) is added to it to make leaks detectable. This gives propane a distinctive smell that is often described as rotten eggs or skunk-like, which is quite different from the smell of lighter fluid, which is more chemical and petroleum-like.
