Hey I just bought a 2019 f350 platinum with 13k miles on it. Not 130k but 13k. Anyway I have 6.0 with like 325k miles on it I use as as welding truck and I’m pretty familiar with the fuel and oil additives that work best for my situation. Is the optilube XPD the preferred fuel additive for the 6.7? Seems like it but I’m just double checking. I have a year of power train warranty left so the optilube will not void this? Should I just stick with the motorcraft? Any suggestions are greatly appreciated. Thank you.
