I was jawing with the guy at the counter of the local injector pump
specialists a couple of months ago and he claimed that bio-diesel was
causing pump failures. His assertion was that regular diesel has
lubricants added to it and that even commercially available bio-diesel
doesn't and that this resulted in much more serious pump wear. I
don't really have any idea how true that is though he did a good
looking job of rebuilding the pump so I guess he isn't a total
wacko... Maybe someone in the group knows more about this and if
there are any useful additives (I'm guessing detergent and lubricant)
that you might want to think about...

The guy at the counter was wrong. Diesel fuel has no added lubricant,
the diesel fuel is in itself provides all the lubrication the
injection system gets.

Vegetable oils are good lubricants as well. During WW I at least one
aircraft engine ran on straight caster oil. It was also used as a
racing lub for years.
