<DIV>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.</DIV>

<DIV>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.</DIV>

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. <BR><BR>Mike M<BR></DIV>

<DIV dir=ltr>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.
