I dunno, I have a buddy that was a diesel tech in the service. Apparently the military runs their "multifuel" diesels on something like jetA. He was always changing injection pumps. This may be a moot point with the MB pump as it is lubed with engine oil but I would add some sort of lubricity additive or 2-cycle oil just in case. If you were getting the fuel for free it would seem very inexpensive to dump a quart of something in the tank when filling up. RT
