my 02 accord takes 4.5 quarts, but it only needs 4.25 quarts each oil change. if i leave the car filter and oil cap off for 3 hours to drain it, it will take 4.35 and no more. a friend of mine has a kit to blow air through the dipstick tube to drain all the oil out. with mobil 1, the process is not neccessary since mobil 1 circulate and clean engine for you.
