I'm sure that you can. But most States have laws prohibiting this. You can also run the risk of carbon monoxide poisoning under the right conditions! Comparing the cost of idling the car for the long periods verses getting a motel room. I think it'd be cheaper and safer to get a motel room. HTH. -Jim


that's just crazy, could cause death, not good for your car. as Jim stated get a room

I have an CO detector in the car. What harm would it do to the car?

Some cars, when idling, don't reach operating temperature or cool down below operating temperature. This can cause sludge and water condensation inside of the engine. Especially if it's cool or cold outside. This will shorten the life of the engine. Possibly greatly. HTH. -Jim


If you look in the owners manual there is a warning about extended idling. Just a bad idea. If you still think about going through with this I would recommend that you have a fancy timed or temp sensors remote start unit installed, with that you can set it to start and run for a period of time then shut down throughout a 24 hour period or a sensor unit will start it at a predetermined temperature and run it till it reaches another predetermined temperature.
