Did my second change yesterday. Got it good and warm and then let it sit on the ramps for a good hour before taking out the drain plug. Despite what the manual says, it's holding 7 quarts of Pennzoil Platinum and still is well below the "full" mark on the dip stick today. These motors must hold oil up in the heads for a good while after being shut down. DIY oil changes mean you can take the time to get ALL of the old oil out in a change.
