OIL? 2001 GT Vert

5 quarts would put you at the very bottom of the dipstick mark, we would always put 6 at the ford dealer, but anywhere in between is safe for the engine, if you put 5 just make sure your engine doesn't burn or leak oil that will bring the level lower in between oil changes

5 quarts is the exact center of my dipstick, every single time. In 01 ford changed the dipstick length (after doing some research) to allow 6 quarts. Not sure why, just know it was done.
