Just wow, with the not crazy intervals using the Ford recommended oil thats pretty nuts if the oil broke down to a point where it destroyed the engine. Would love to see an oil analysis done to see if the oil really failed, or there was some other oil system related issue like the pump breaking. Another potential is if you were running a bit on the low range of normal and driving hard , seems these engines are known for oil pressure problems due to the shitty shallow plastic pan with little in the way of baffles.
This is reinforcing my decision to pre-purchase the fenfab upgraded oil pan and keep paying for premium Amsoil or other top rated full synth.
