RWThomas1,
Only the "crankcase " of the MB injection pump is lubricated my engine oil. The barrels and plungers are lubricated by the fuel as are the injectors.
GREG,
The only top end lubrication you have to worry about is the top end of you injection pump where the fuel lubricates the barrels ans plungers. So a little top lube wouldn't hurt since you get the fuel for free.
