I was always told to take the car for an actual drive (including a highway stretch) to achieve these ends, otherwise the moisture you're expelling accumulates in the exhaust system.

Since I have yet to see any of these various claims having any impact on the maintainability or function of my car, I think I'll stick to my plan of not wasting the gas in my engine for months at a time.
