Ford has been using GTX Prof 15w40 in my FG. Is that known as Castrol GTX Modern Engine in the red bottle? I had a look online and that's what comes up but it doesn't even say if it's semi or full synthetic. Should I just keep using this or tell them to use something else?What oil is everyone using/recommend? Link to comment Share on other sites More sharing options...
