500 engine hours = ~15,000 miles

  • Using a 30.0 mph equivalent factor for Passenger car - mixed city/highway, 500 engine hours converts to roughly 15,000 miles.
  • Engine hours measure wear more accurately than odometer miles for equipment that idles heavily, like tow trucks, RVs, generators, and farm equipment.

Next stepCheck your OEM service manual for the official engine-hour equivalency factor, as manufacturer figures vary from 25 to 40 mph. Using the correct factor gives a more accurate maintenance schedule.
