Is it bad to leave the engine running while in park?

Why would you want to? For all the reasons mentioned above, it's not a good idea to leave a car unattended with the engine running, in a park or anywhere else. The waste of fuel is the least of your worries. The car could move, especially if parked on an incline, and would certainly be stolen. I doubt very much if you'd be able to claim on your insurance as the loss would be your own fault.

I always shut my engine to avoid waste and noise, but it is remotely possible that an engine idling with no load given clean motor oil might polish itself. I don't say that this is scientific. It is more widely agreed that running at highway speeds is good for a car. The amount of wear taking place when the idling engine is doing no work must be insignificant.

Well it does do a little more wear and tear on the valve train and piston rings have been known to stick causing oil burning problems. It s due to the lack of load on the engine for an extended period of time. Never a good idea. Some of these answers you got are wacky!

Some gearboxes do not lubricate properly in park and may damage the box if left for any length of time. You need to read your car manual to find out.

Only if you are wishing someone would steal the car if it is unattended. Otherwise, no damage what so ever would happen to the car or engine!

Yes it is. It's not safe to leave ANY vehicle unattended while it is running.

Hello

It is designed to be. But like any car the shorter time the better as it will over heat as you are not moving

Bad for the environment and your wallet, otherwise no, apart from making it easy to steal.

fuel economy goes to heck but it is not bad otherwise as long as the fan can pull air through the radiator.
