I have always added a qt of ATF to all of my Ford Powerstokes every 5K miles at service time since around 1985 to help increase injector life. Not sure if it works or not. But have not had to change many injectors out after warranty period has expired. Some have run up to 675K miles. That being said. I have not put any in the Newell 8v92 yet.
