I have a question....
Why does FP3000 / Plus recommend using LC20 in conjunction with it, yet there is no similar recommendation when using FP60 (that I can see)?
Does the former have a negative effect on motor oil TBN, thus the recommendation for LC20?
Just curious. My 2 gallons of Plus arrived today and I'm hesitant to run LC20 in my 7.3L PSD unless you folks think it's ok. As for my 5.9L CTD, I'm not hesitant due to the electronic injectors.
So, I'm wondering if LC20 is simply recommended or actually necessary with the Plus.
