I brought my V60CC in for an oil change this morning then to set up another oil consumption test. I checked my oil after letting the car sit for a few hours and it's overfilled, is this common? Is the dealership trying to get out of doing a ring job by having the oil be full when I bring it back? It says they put 6q in but the capacity is 5.8. Could .2 Q really move the oil level that high on the dipstick when on a flat surface?
