to begin with, I pull the dip stick, open the oil fill cap and break open the oil filter cap. This will release most of the oil out of the oil filter housing.
I then use a 19MM or 3/4" socket to remove the drain plug and always replace the copper gasket otherwise you WILL drip oil.
While the oil is draining (it will take a while) I move up top to the motor and replace the oil filter, its pretty straight forward it just un-snaps and snaps in the top of the plastic cap. Remember to replace the gasket with a new one and then I put it back together being careful not to over tighten the plastic cap
By this time most of the oil should be drained and then I pour 1 to 1.5QRTs of fresh oil in the motor and let it drain out to get the rest of the dirty oil in the bottom of the pan.
Install the plug with a new cooper gasket.
While I'm under there I go ahead and drain the water seperator for 30 seconds too
