Sorry about that I ment add to fuel !
You might want to check in with one or two of the many Ford diesel forums.
I use fuel additives that Cummins recommends in my 5.9 engine however what my engines needs can vary from other Cummins owners in different temp zones or a host of other differences.
Do you buy fuel from one supplier or retailer.
Go to a ford dealer and buy the additive that Ford recommends for the older 7.3 engines.
Additives that worked for the 7.3 may not be compatible for the new 6.7 engine
I would also check out a few of the many Ford diesel websites.....and pay attention to what other 7.3 diesel owners use or say. The new gen diesel engine may not use the same type of fuel additives.
