Hogwash. There is no concrete evidence that ULSD has a lubricity problem, only guessing, assumption and finger pointing to a convenient scapegoat. A few random and isolated pump failures are not "proof" that ULSD has a problem. Pumps have always been failing, thats how Diesel Injection shops have managed to stay in business for decades before ULSD's introduction. We hear about more pump failures now because more people than ever have internet access to communicate their problems to the masses.

what do you recommend as a lubricant until further info is available?

Nothing. Anything you add to the tank besides fuel is a waste of money. Just because the bottle claims it can increase MPG by X% or pay for itself does not make it true. The "Tornado" intake swirler claims it will increase MPG but we all know it does not. Why does it continue to sell? People
think it works.
The only two times an additive is useful for Diesel is anti-gel in extreme cold and biocide for a fungi infection.
