When the oils filled back in the truck to its recommed level in less than 3 days its out and the truck will lose all power shut down and the check engine lights come on.. any ideas? corry little

I think that if your engine is consuming that much oil you have a serious internal problem. Get it to a Diesel specialist or a Ford specialist ASAP, you're lucky you haven't had engine failure yet.
