Just got an update. So I was right after all. My service advisor called me back and told me that the fuel filter is supposed to be replaced at every second oil change

So make sure you all get your fuel and intake air filter replaced every second oil change. If they refuse, refer them to the attached file. It states this on page 11;

Emission Control Maintenance
