I've been gone from France too long. I've never heard "station de lavage" before.

Very awkward and formal. Anyone would call it lavage auto, lave-auto or simply lavage if the context is clear.

Maybe I'm too old or my family was weird. We called it "le carwash" with a beautifully French "carouache" pronunciation. But yeah, "lave-auto" sounds more familiar.
