If you live in a hot and humid environment and park with the AC on or remote start a truck in the winter time to get it heated up, the high idle option is perfect to prevent issues.
Most people's idle hours build up way faster than they would ever expect it....the idle hour meter Ford started putting on these trucks has really enlightened some folks on how much they actually idle.

Thanks, I had assumed that the engineers would work all that out in the ecu programming.
