Winter storage
In my end of the world the car goes into storage when the snow stays on the roads (the average date is November 22) and stays my hilly quarter-mile driveway is snow free, along with the roads. Dropping liability and collision is a simple email to my agent and saves a couple of hundred dollars. Unfortunately, my motorcycle policies do not allow the same.
You all remember from high school chemistry that burning hydrocarbons releases primarily carbon dioxide and water (plus relatively small quantities of other stuff we call pollution). The problem is that until the oil gets up to around 212F, some of the moisture in the exhaust gasses are absorbed into the motor oil. Above this temperature all moisture is vaporized... the oil can't hold moisture above its boiling point.
But, you must drive the car in order to get the oil up to this correct operating temperature of around 212F; it will probably never get there just idling even if the coolant gets to its operating limit. Add to that the fact that when cold, engines operate on their "fuel-rich" open-loop program, which exacerbates the moisture problem. Plus, the catalytic converter never "lights off" at idle because EGTs are too low.
