Such a time I've had today with changing my new truck's oil for the first time. I'd like just a few minutes with the ford engineers concerning all the BS that has to be done prior to actually changing the oil. Well anyway, the oil is changed and the covers under the engine and transmission have been set aside for the time being. In changing the remaining oil life back to 100% is kicking my butt. I must be missing something?? The owners guide tells you to hit the setup button to cycle through the features, mine is the one with the 4 arrow buttons and the ok button in the center. I have tried about everything to get this thing to reset back to 100%. so far no success, can anyone explain just how this is accomplished?? Thank you!!
