greetings:
  help me with the math...  10M revolutions at highway speed (2500 rpm) will
be used up in 4000 min. (4000m * 2500r/m = 10Mrev)  that's about 66 hour, or
about 5 days (straight), which at 60 mph is about 4000 miles.  did i do this
correctly?  if so, i have a newfound respect for the mtbf of most engines!

later,
