" inferior oiling system"
Just like all the other engines from companies who don't recommend 5w-20.

WHAT THE #@$%!
The 4.6 L SOHC doesn't have 6 quart capacity, the 4.6 DOHC does.
Valve-train design is the reason for the 5w30
The 4.0 V-6 is imported from Germany. I'm surprised that 5W40 is not specified for it, as most German engines specify a heavier oil.
I've noticed that older engine designs usually specify a higher viscosity oil. Is this the case here?

Perhaps you missed reading Eric Smith's post?
Some Ford engines will have more sliding friction type components & require a higher HTHS than the typical 2.6 of a 5W-20.
Ford knew from the get-go that not all the Ford engine designs could handle 5W-20.
From a late 2000/early 2001 press release:
"The Ford Escape will be the first new model shipped with the new oil. All Ford 2001 model year vehicles - except the 4.0-liter Ford Explorer, 3.9-liter Lincoln LS and 3.3-liter Mercury Villager - will be shipped with the new oil as they go into production later this year. Eventually all new Ford vehicles will use the new oil."

In older car applications, the 4.6L sohc had a 5 quart capacity.
The 4.6L trucks always have been speced for 6 quarts, including my 98 f150.
Per the Motorcraft Oil Application & Crankcase Capacity Chart, the following are the 5.0 qt applications for the 4.6L engine.
4.6L -2V REP Mustang (95-02) 5.0 qt
4.6L -2V REP Crown Victoria/Grand Marquis (92-02) 5.0 qt
4.6L -2V REP Town Car (91-02) 5.0 qt
4.6L -2V REP Mustang (95-02) 5.0 qt
4.6L -2V REP Crown Victoria/Grand Marquis (92-02) 5.0 qt
4.6L -2V REP Town Car (91-02) 5.0 qt
They don't seem to be avialble any more, but at one time you could download manuals for different vehicles and different countries at the Ford site. You could see vehicles spec'd for 5w20 in the US and thicker oils elsewhere. Design aside, load and drain intervals are also a factor.
the 4.0L Cologne is known to wear the tips of the pushrods causing them to mushroom and wear out due to no/poor oiling provisions for that section.
btw the 4.6L SOHC in my mustang takes 6 quarts, both according to the dipstick AND the owners manual. my 2000 Grand Marquis with a 4.6L SOHC takes 5.5qts.
most mustangs with a 4.6L take 6 quarts. ive seen a lot of DOHC 4.6's in cobras take 6.5-7 quarts.

The Ford 4.0 SOHC has pushrods?

there were 2 4.0 v6 motors in the Exploder the OHV and the SOHC.
