I have a new 2015 platinum expedition. The day I got it, it smelled really bad. I had my husband smell it and he said they must have spilled oil on the engine. Well today after driving it for about 5 minutes it heated up (although temp control says it was ok). I parked in the garage and 45 minutes later I went out and the entire garage stunk. The hood was throwing all kinds of heat and was really warm. Tonight my husband went out and pulled the dip stick. It was extremely light and smelled like oil and gas combined (smelled like a skidoo lol). Any thoughts as to what it could be?
