Hopefully Opti-Lube XPD will be included in the new tests. I've been using Opti-Lube XPD since I've owned my truck and curious if it's still the additive to beat.
 
its because of the first study that i changed form diesel kleen to optilube and i think my fuel system couldn't have been happier.

Started running Optilube after the first study as well. Injectors seem very happy):h
 
I willing to donate a gallon of Opti-Lube XPD if that would help.
