Mine is 12 and 2. Also get the test kit for the Antifreeze so you don't cavitate the block. Or follow the Ford maintenance schedule and put the additive in every 30K (IIRC) I use the test strips from Fleet Pride, mine checked okay at 35k miles. I usually check it every oil change. I also keep a bottle of the additive on hand.
