What happens if you leave your car running for 8 hours?
Leaving the car running all day won’t do any damage. A modern car can run for days and days until it runs out of gas, if the engine’s cooling system is working normally. A. There are a number of ways to cool your car, but the most common method is to use a fan. The air is then forced through a series of pipes to the outside of the vehicle, where it is cooled by the surrounding air.
This process is called convection, and it’s what keeps your engine running at a steady speed. If you don’t have an air conditioner, you can also use an electric fan to do the same thing. However, electric fans are more expensive than fans that run on compressed air, so you may want to consider using a gas-powered fan instead.
How long can a car idle without damage?
Idling your car for 30 seconds to a minute is not harmful to your vehicle. Even if you shorten the duration of your car’s idling, it won’t damage the engine. If you have a car that has a manual transmission, you should start the car up as soon as you get out of the driveway.

“It’s not a good idea to leave your car unattended in a garage, especially if you don’t know what’s going on inside the vehicle,” said Dr. Michael J. Osterholm, a professor of environmental health sciences at the University of Minnesota and a co-author of the study, which was published in Environmental Health Perspectives.
