oil changes

I did not want to hijack the synthetic oil change thread, but it brought up something I have found odd. I schedule all the maintenance on a large fleet of industrial equipment and it all calls for an oil change every 250 Hours which is 4 times a year if ran a good solid 8 hours a day.

Now lets say I drive my car 50 MPH for 250 hours that is 12,500 miles of course the manufacturer recommends an oil change every 3000-5000 miles is my car engine such a P.O.S. compared to a forklift engine???
