Re: Adirondack Case Guy: Not long ago, heating oil in NY was the same as off-road and farm diesel. Had better lube then diesel at the pump now. So, no big surprise you did okay with it. I've used it for years. Bet you won't do so well now! Last year most suppliers in NY switched and now heating oil is separate from farm fuel and has NO lube added. Might get away with it in n in-line and/or piston pump injector-unit. Not in a rotary.
Re: Allan in NE, David g, Bob, Buick-Deere . . . very uninformative blanket statements with no useful content. All one needs to do is read a CAV or Stanadyne document about what their lube requirements are for mechanical rotary-distributor pumps. Then see if the fuel you are using meets those specs. Some does not - plain and simple.
Or read the service bulletins from Stanadyne re premature wear on the transfer-pump blades and the special kits Stanadyne offers for use with low-lube fuel.
Or the many documents re. failure of Stanadyne rotary pumps in the US military that suffer head & rotor wear in GM diesels.
I've seen that most people on this forum (that comment) send their pumps out to be fixed and rarely attempt to repair themselves. Yet - these same people are experts on injection pump wear? Good grief!
It goes like this. The major metal moving parts in a distributor pump e.g. a CAV, Stanadne/Roosamaster, Diesesl Kiki, Bosch VE, AMBAC, Rotodiesel, etc. - can last over 1,000,000 road miles or 30,000 engine hours. Who - at this time - will know if their pump life has been cut in half or to one third? Not many I suspect. If you buy a so-called "rebuilt" pump - it likely already had parts with very high hours. So when a pump craps out - we rarely know how much use the parts inside have and what the cause is.
Now - to the rare situation where someone has a brand new (not rebuilt) pump and it gets a scored head & rotor or ground up transfer-pump blade - then we have something to diagnose.
You naysayers - yes- you will spout out whatever makes you feel good but that changes little. To the guy spends a little extra adding lube to to his/her fuel? Something wrong with a little insurance? Hey Buick-Deere. Do you have fire insurance on your house? If so why? Is it on fire? The reasoning much different with adding lube to pump diesel that just about always has less lube then the older diesel fuel. I guess by the naysayer's reasoning -it's fine to spend lots of money on "rebuilt" pump but silly to use any sort of insurance to preserve the life of what we've got that works at present?

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
