Depends on the car and how clean it is prior to that change -
Anything unknown or shown to be dirty last filter opening gets a 1-1 oil to filter change.
If its whistle clean last cut - Ill topside suck out the oil and just leave the filter on - I run mag drain plugs.
If you are bothering to take the filter off at all - just replace it.
