Never have.

I've always oiled mine after use and have not had any problems. Yes, it means degreasing them before the next use, but never felt put out by it. A quick shot of some manner of degreaser (gun-scrubber, brake cleaner, etc.) and usually by the time it's at operating temperature the oil is burned out. Not to say it's the only way, just the way I do it.

For me, oiling something I don't want to rust is sort of like keeping any holes covered that you don't want a dirt-dobber nest built in, it's just something you do.
