To put the power-over-overhaul-run into a more comparable perspective, I think it's helpful to compare the gallons of fuel consumed [as a proxy for the amount of energy/work output]. A small aircraft engine like in a 172 might be 10 gallons per hour, or 18K gallons of flight time over an engine run.

18K gallons will take a typical road car around 500K miles, so an airplane engine getting "only 1800 hours" of flight time likely outperforms the typical auto engine.
