I disagree with putting the quantity of oil listed in the Owner's Manual (as the engine's capacity) when changing oil. No matter what method you use to drain the old oil some quantity will remain in the engine. At oil changes I add all but the last quart, run the engine for a few minutes, turn the engine off, check the level on the dipstick, then add some portion of the last quart so that the level is halfway between the min. and max. marks on the dipstick.
