You want to run an engine once a month or so to keep all the internal parts protected from rust by a thin film of oil. It is best to let it heat up all the way to drive out as much moisture as possible.
Internal rusting is a big issue on airplanes that do not get flown often enough. The first thing to go are the cam shafts.

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. Looking around the neighborhood, I assume the people with the rusted-out mufflers are the ones that just let it idle.
- dekhn 4y agoIn fact there was just a PR blitz about not idling to circulate oil: https://cars.usnews.com/cars-trucks/features/aaa-says-dont-warm-your-car-up https://cars.usnews.com/cars-trucks/features/aaa-says-dont-w... 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.
