Since you use PM-22A and recommend everybody "use some sort of additive that adds lubricity," do you know what exactly is in PM-22A that adds lubricity?
Not directed at me, but I'll take a stab at this one anyway.
Best answer is no, I have no idea what does add the lubricity. However, it is advertised right on the bottle that it does add lubricity, so I guess I must take Ford at their word on this one. It is also listed on the so called document in question, of which I have a copy on my computer.
In my mind, considering:
a) the admittedly small number of failures, and
b) also considering that two failures from just members here on the forum were subject to Ford's attempts to weasel out from warranty(Ricatics was denied warranty, a Canadian forum member told me in a PM that Ford tried the same with his, but had to warranty it since they had just done a fuel filter change service on his vehicle at Ford)
then at the least using a Ford approved product is not something that would be a mark against me in the event of a similar warranty claim on my part.
That said, it would have been nice had the Ford PM-22A stuff been tested in the old Diesel Place lubricity study done some years back.
Stanadyne, Schaeffers, and Opti-Lube XPD products did extremely well in those testings.
In fairness, some here have seen an exceptionally long thread on the Ford 6.7L diesel, where some "intelligent" types tried to figure out what was going wrong with the pump.
The one point relevant from that thread is the unknown affects diesel fuel and diesel with additives undergoes within the pump itself due to the very high operating temperatures and pressures produced in the pump.
It would certainly be a shame should an operator, like myself, in an attempt to increase lubricity of the fuel, actually cause more harm due to the interaction of the additive with the pressures and temperatures in the pump. One must consider that this pump is generally always running twice the RPM's that the engine is under most all conditions.
It is a situation impossible for someone like me to know for sure. But, given the certainty that the fuel in the US is too dry for this pump right from any filling station, I will err on the side of trying to do something better for my vehicle and continue to use lubricity additive.
