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.

Max, not sure camshaft placement has anything to do with it - my Audi A4 has a
DOHC set-up, 20 valves, with an oil cooler, and only holds 4.2 quarts....! So,
must be a question of higher efficiency, as you also noted....
