Ran Amsoil Signature Series 15w 40 in my 2011 and now running in my 2017. Not a problem ever came back on the lab reports. Been going by the lab for oil change intervals which has never exceeded ford recommendation. Ford also states in the manual for bioblend fuel to run either 5w 40 or 15w 40 for my MY17.
