B737 NG – Oil Quantity Readout

[Prop's ????]

Can anyone advise me when the oil quantity (OIL QTY) readout on the lower DU changes to a reversed video and reads LO? I understand it changes when the quantity is low, but at what quantity?

PROP`S???,
A LO message shows when the oil quantity is less than 4 US Quarts(3.8 litres) for 35 seconds.The oil quantity shows in reverse video when the low oil quantity exceedence is active.

Note an oil tank full capacity is 21 US Quarts (20.2 litres)
