I just saw this in a new Toyota owners manual:
--------------------------------------------------------------------
Oil capacity
(Drain and refill - reference*)
With filter 3.9 qt. (3.7 L, 3.3 Imp.qt.)
Without filter 3.6 qt. (3.4 L, 3.0 Imp.qt.)
* The engine oil capacity is a reference quantity to be used when changing the engine oil. Warm up and turn off the engine, wait more than 5 minutes, and check the oil level on the dipstick.
