Plus the injectors are way below the res & if they could flow without running, then the res would always drain. Bottom line is, the oil doesn't need to be changed in the res. Just do a oil change like normal. At least on mine it' slike that. Who knows if there's problems, or im proper gaskets that block the "low" pressure return gally. Don't know & don't care. Mine is fine.
