Engine hours track equipment runtime independent of distance. Essential for boats, generators, construction equipment, and fleet vehicles. Conversion to miles helps estimate maintenance intervals and resale value.

Pro Tips

Check your manufacturer's manual—some commercial vehicles specify maintenance by hours rather than miles.
If your car is used for delivery or towing, use a lower average speed (20-25 mph) to account for higher stress.
