Well, the old "this is what we did in the past" may come back and bite some folks in the back side. The Tier 3 and Tier 4 diesel can be pretty finicky characters with those DPF and SCR/DPF systems, let alone the crazy common rail pressures that have became part of the scene. I have seen the look on more than one owners face when they had to replace a DPF filter.
But this lubricity thing is mostly a ruse to get folks all worked up. I go thru 21,000 gallons of diesel per year on average. I have been using ULSD since it's introduction (roughly 2006), running trucks roughly 135,000 miles a year, no additional lubricity additives put in to compensate, just winter fuel treatments and biocides, and the last injector I lost was in 2001, long before ULSD even was a blip on the radar. I have had ZERO fuel system related problems due to ULSD.
Check with any major OEM dealer shop or authorized repair facility. ULSD has not been the gremlin that many folks seem to think it is. There may be some other issues that ULSD has, especially regarding additional retention of water and easier for microbes to set up shop in fuel tanks, but lubricity has not been one of those issues.
