Whelp after doing a couple oil changes, got tired of ...

• aiming the oil bottle opening towards the oil filler. *5quart / gallon jugs are worse that quart bottles.
• cleaning-out the special funnel that I cut the end down so that it wouldn't hit the timing chain.
  etc., etc., etc..

... only to still spill some oil!!!!! *SIGH*

SOLUTION: A pre-owned oil filler neck from a 2006 Explorer 4.6L (for cheap).

NOTE: Had I not found pre-owned, the next option was a new oil filler neck from a 5.4L - part # 3L3Z-6763-DA

Nice, I just use a small funnel, works for me.

ETA: How does the tube fit into the hole?

Has the same half-twist-thread (and O-ring seal) as the cap.

A long neck funnel at Wal-Mart for $1.85 works really good.
