If I turn on my car and let it idle for hours on end, does that count as "miles driven?" Example, I buy the car new with 0 miles. I idle the car for hours daily for a month. Over that time, will it actually show miles were driven because the engine/RPM was running? I am trying to sell a car and don't want to add mileage any further but do turn it on once a week so the battery does not die.
Just drive it in reverse as much as possible and you will reduce the miles on the odometer.
Generally no. I can't think of a single vehicle where the mileage ticks up with the engine on without the transmission rotating. However, large trucks (including our Duramax) also tracks hour rating of engine usage. We've got over 4,000 hours on ours.
This got me thinking. What's the hour rating of a car with 100,000 miles on it? At a 40 mph average, it takes only 2500 hours. There is idling of course but still, it's a lot less than I thought. How did you rack up 4000 hours?

Nope mileage only increases when car is rolling but a lot of new cars today have hour meters built in the dash displays

Why not test the theory?
Go out and look at the mileage, take a picture or write it down.
Then run the car for 10 minutes, then compare the current mileage to what it was before you started the car!
Just to be sure, do the test again but this time run the car for 12 minutes instead.
miles driven is based off TIRE revolutions, not engine revolutions. when you idle the engine you are getting zero mpg because you are not going anywhere.
No. It measures off the transmission. If you disconnect the drive shaft and run the car in gear wit hut moving, you will log miles.
Just leave your A/C off. Your odometer is run off your A/C.
