The Motorcraft conditioner restores the lubricant that is missing from today's fuels. I was wondering if the 6.4 had accounted for this, in it's design, and eliminating the need for the conditioner.
i think you mean fuel pump. the hpop (high pressure oil pump) is oil only and never touches fuel. if it sees fuel, you got a serious issue somewhere.
the lower sulpher dried up seals that werent made for the lower lube. injectors too.
but ive been running diesel kleen for a year and a half and the whole life of me owning my sd since last aug, i dont see any gains.
