IF it starts to leak, you need to take it somewhere that they will ACTUALLY follow the replacement procedure from Ford. Some didn’t leak. Most in fact. But, once they leak, the replacement procedure has to be followed precisely, and I believe that procedure involves a long cure time before refilling and most shops aren’t willing to give up a garage bay for this. In my narrow, military mind, it’s this reason alone they went (back) to the metal oil pan. Shops just wouldn’t follow the instructions properly.
You’re not hitting them fast enough.
