A few months ago I talked with one of the owners of Apollo Express which is a trucking company in Jackson MI. He said they have 5 delivery trucks with the old 7.3 Powerstroke in them. All 5 have over 500,000 with no repairs to date. I asked how ofter they changed oil. He said they schedule them for every 7,000 miles just like the big Freightliners they run.
I could kick myself for selling my 2002 PS. /forums/images/graemlins/frown.gif
