The owner's manual states the capacity is 6.4 quarts when also including the volume of the oil filter or 6 quarts when not including the volume of the oil filter. However, it appears that the 6.4 quarts makes it a little over full, so I suggest adding the 6 quarts,run engine for a minute and then check how much more of the .4 quarts to add.
