Long continuous runs are the best for getting lots of miles out of an engine.

For your typical user, a million miles would be 40-60yrs, so not particularly relevant.

Most engine wear is the start/stops and moisture build up from short trips. On another forum a V-10 in a airport shuttle that run almost continuously was reported to have gone 900k miles.
