Wayne,
I stand corrected. You are absolutely right. I completely forgot about
the sulphur content. Big difference. I was told by a mechanic that the
sulphur partially lubed the injection pump and the low sulphur in todays
diesel fuel is one reason the expected life of an injection pump has
deminished. He recommended using an addative to lube the pump at least
every third fill up. I followed his advise and have not had a pump
failure since.
