Burned, I don't think so. Eaten, more likely. They service department topped it off before the consumption test at 1800mi, and marked the dipstick. It is reading low at the moment. No smoke, no signs other than "maybe" some power loss. Hence why I am now calling my truck a lemon. Its already been backed into(rear wheel, slight scratches) and a nice half dollar sized door ding. Soooo, I now get to have a discussion with Ford and my dealership about how I ordered a truck that was supposed to get me from A to B and not be in the shop once a month. If they come back and need to swap an engine the conversation will turn more serious, in that I ordered a truck with specific matching numbers and not a new truck with a newer engine, better get a new one built before my lawyer files. But this is all just typing until I have an answer next week.
