I've seen these numbers so often on this site, what's a good rule of thumb for engine hours to miles conversion? Running PTO based operations (dumps) so we change our oil between 250 to 300 hours. The more I think about this, the more I think the intervals too long. We are under 5MPG consistently. Might hit 6 on a good day.

depends on how hard you work it.. but most of the time hours can be converted into rough-miles by multiplying them by 48 - 53.

EXAMPLE: (typical highway truck)...
8,000-hours * 48 = roughly 385,000 miles

EXAMPLE: (typical highway truck that is worked hard, low rpm's used, and has low fuel mileage)...
8,000-hours * 53 = roughly 424,000 miles
