Wouldn’t it be logical to say that if they added a drain plug later on that they realized that it wasn’t a lifetime oil? And after coming to that realization they would have sent every Ford dealer instructions on how to change the fluids? Although I am no mechanic, I’m handy enough to do this type of thing as well as having a garage to do it in. My son is stationed at Ft. Bragg and lives in the barracks so there is no place him or I to do it. Two local Ford dealers in the area but only one has done it. It’s aggravating as **** making several calls to finally find someone that understands what’s involved with a fairly simple fluid change. Thanks to all for the replies.
