Yes, interesting. I will have to ask one of my "know-it-all" friends.
If I had to guess, I would think total oil capacity is governed by how
much is in use (i.e., not in the sump) when the engine is running. Does
the Toyota Tacoma have variable valve timing? That must use up some
extra oil volume.

Interesting points. I don't know if the factor would be improved oil,
or
improved oil circulation design (more efficient use of the volume of
oil).
The Toyota engine is doubtless an OHC design which would naturally have
more
internal oil passage volume than a pushrod motor.
