Ok, this is going to sound like a silly question/statement. I’d never heard of a hour meter in a truck. Is this in a standard pickup? If so, when roughly did that start and how do you access it? Would my 2002 F250 have such a thing?

Jim, I keep forgetting to check the hourmeter in my truck, but my car has a direct readout of average MPH.  I record it and reset with every tank of fuel along with MPG data.  The overall average of just under 3 years and just over 40K miles is 35.5 MPH.  Turns out I'm remarkably average.  I wear size Medium suits off the rack too.

Several years ago, my brother and I were comparing odometer readings on our trucks.  My truck was older and had a lot more miles.  Then we checked hours.  His had a bunch more.  His truck use was probably pretty typical, including a fair amount of local driving.  As I recall, he averaged close to the expected 35.  I rarely use mine to just drive around on short errands.  Most of the mileage is on longer trips.  Earlier today, it turned over 100,000 miles and is just over 2,000 hours.  The average is 49 mph.  Since my highway speed is usually 70 or more, it seems it would be tough to get a long term average much higher.

Back in the good old days, hour meters were typically grounded through an oil pressure switch.  If the engine wasn’t actually running and producing oil pressure, the hour meter wouldn’t clock time even with the switch on.

I have a Scag zero turn that I bought new, I put about 350 hours on it over the course of several years.  When I parked it this last fall, I accidentally left the key on, so when I went to start it this Spring I had 3500 hours on it. Fortunately my daughter works at the dealer so I was able to buy a new one.

For the record, in automotive engineering, the conversion between engine hours and road miles is usually taken to be 35, not 60.  I've also seen 33 used.  It's a broad approximation of course  Vehicles used extensively on the highway will be somewhat higher, and vehicles used extensively in heavy traffic/city conditions will be somewhat lower.  It would be exceptionally rare to find any roadgoing vehicle averaging 60mph.
