Go for 8 its never wise to max out the system because you never know what conditions could cause the level to rise again.
If you fill it 1/2 a quart then drive the car for about an 45mins/hour so it heats up as high as its gonna get under normal driving then let it sit for about 30 mins and check the level again, repeat the process until you have the level where you want it.
The MFD should display the changes instantly but you cant guarantee that its accurate until the oil has been heated and all had a chance to return to the sump.
