Changed oil and filter. Drained both front and back of oil pan. Filled with 5 quarts. Dipstick shows 1 inch above full mark. I was told before "just mark the dipstick at 5 quarts and live with it". The dipstick is the correct part number per the ford parts website (F1ZE-6750-DA M). The car had work done to it before I got it but I cant see someone changing the dipstick tube. Does anyone have an explanation for this?
