For lubricity for your pump, I use either optilube or Hot shots. both companys have products for just lubrication that's vastly superior to 2 stroke oil. Optilube had studies that show how much better it does over alot of other competitors in an independent lab study. Hotshots is a newer additive and is also great for lubrication, preventing rust, cleaning, cetane, etc.

no clue......

But is those millions of miles in a newer diesel with a modern ejection pump as I had asked? Or millions of miles with a old db2 injection pump, with ULSD where as ULSD did not even exist yet?

Answer: No.

Many do run a 2 cycle oil in these old dogs to protect the pump, due to the very known lack of lubrication in ULSD. I do, and the truck run noticably better with it than without.

The notion that no adding a lubricator to the fuel is a bad notion. It can only help, if used properly.
