It is standart procedure, that technicians overfill the engines. Since they make extra profit on sold oils, they put the maximum amount the manual states, while trying to do the job quickly never fully drain the crankcase.
I am putting 8 quarts into the engine having 8.5 capacity and regardless taking my time to drain the old oil, I am getting close to the full mark.
When you check the oil level short time after stopping engine, it is always going to show lower, since the oil from the heads take few minutes to drain to the bottom.
