Not sure. You did mention that some programming updates were done by Ford dealer, right? Maybe that changed something? Your fuel has gone up, relative to the OCI duration. If all other things are held equal (driving pattern, environment, loads, etc), then either the recall update had something to do with it, or you've got a leaking injector perhaps? Nothing to panic over yet, but I'd keep an eye on the fuel. Perhaps take a sample (not chainge oil, but sample oil) at 5k and then 10k miles and see what's going on? Maybe look into getting a Fumoto (or other brand) valve and sample a bit more often until you get the rising fuel issue identified.My last 3 OCI were roughly 20K miles with one being 24K miles. Yet this OCI at 20K had fuel dilution around double of the prior two OCI. What would cause this?
