has anyone actually run regular motor oil? rp actually suggests 10w-40 oil for ford mtx using XT-M5-QS spec
WSD-M2C200-C (ford honey). amsoil suggests 5w40 oil with some type of additive added. and blackstones results showed that the ford honey was more of a 15w40 diesel oil. rp recommends sychromax for ford mtx that call for atf. but if ford changed from atf to the honey should the old recommendation be discarded along with fluids that match that old recommendation. after reading that whole thread it seemed we are looking for a fluid that matches the honey as much as possible without ep additives. the amsoil mtf sycromesh was mentioned but everyone seemed to skip over it. its 7.70 a quart which isnt bad. but its a 5w30 so i dont know if thats any good. there was so much talk that the ford honey is a 75w90 gl3 or gl4 gear oil that it doesnt seem this would be a match as a replacement
