The vans are -supposed- to get serviced every 5k, but the reality is that it often gets pushed beyond.
I think the 5.4 for the Econoline is the older 2 valve motor w/o VVT. Ford probably realizes that the van buyers are mostly commercial customers, so they keep the drivetrain simple. Don't know about the 4.6l, but I bet that it would still be ok, as it's in the lighter-duty E150 range.
As I recall, the 2-valve 5.4l has a forged crank, oil cooler and was designed for HD "severe" service.
Also, the 5.4l has a 6 or 7qt sump which helps too.
Thanks. Yes I bet the larger sump helps a lot.
