87crewdually posted--Divide the miles by hours gives you the average speed. > 35 is frowned upon and reflects more than normal idle time.
In my mind in a perfect world anything 50 and above would show mostly highway miles--so yeah at 25 I imagine your truck idled ALOT--but who really knows. Heck by the time you're done wrenching on yours i might consider it close to brand new
or at least the inside of it is clean as new

According to Ford 1 hour = 25 miles. I have 4065hrs which comes out to 101,625mls. Mean while the odometer reads 116,648mls. When I first got the truck it was the opposite high hours and low mileage. Basically the way I see it (I could be wrong) I have 15,023 idle miles that works out to 600.92 idle hours.

It's interesting that a similar question is being asked today on a Glastron boat forum except it's boat hrs vs. car miles. On the Glaston board the question is how do you compare boat engine hours to equivalent road miles to gauge the engines health and life cycle?
I do have low speed miles to and from work and several highway trips a month. Based on that I change the oil and filter on my '99 7.3 at 4,000 mi. and fuel filter twice a year.
The boat gets serviced once a year with maybe 20 hrs on it.

87crew, Yeah I get that and yes I know about the service intervals. I guess where I am getting confused is, on newer trucks they actually call out "total hours" and "idle hours". So I was thinking maybe there was away to do that with older trucks too?

I hear what you're saying, but there isn't a way to figure it on our trucks accurately, just a lifetime average.

The PCM doesn't differentiate between idle time and normal run time. To do that it would have to keep two different times, one as it does now and another time that logged if it did not see a wheel speed input or an increase in idle threshold.

Almost.
I installed a factory TBC module and upon programming, my hour meter was set back to zero.
Prior to the setback, I believe it had 1640 hours plus or minus 5.
I only remember because I wrote down the mileage and hours at the previous oil change.
