All depends on the filter and how patient you are. I know with my truck, if I put 4.7L in, it will be a little over, after it all drains down, but it doesn't worry me.
I use a Quaker State QS8A filter, have been for the past two years with no problems.
It does allot to do with the filter I think too, my old fram vs my new bosch filter with the same amount of oil reads differently. The fram one had a higher oil reading then the bosch, same size filter but the bosch would hold more oil.
