I have been researching archoil products and I have a few questions from those who have used it. My truck is a ‘14 with the 68RFE. Deleted and tuned by DRD. Other than that it is stock. I have decided to try the oil additive but the fuel treatments have me puzzled. Since I am deleted will I see any benefit from the 6400D? Will the 6200 be enough? Should I do both? Not a lot of information on which one would be best or using both one after the other.
