It was explained to me this way, and it makes some sense: We all have used diesel to clean various engine parts, right. Why? Because it excellent at removing grease and oil. From what I understand, high sulfur diesel had lubricating properties where the LS diesel does NOT (or not much anyway). Without the HS diesel, the rods within each injector and the distribution pump components will wear much faster. Also, if an injector is NOT atomizing well, the LS diesel can wash the cylinder wall clean of the film of oil and cylinder wall will become scored.
Speaking of "stupid boating tricks" How about thye suggestion I've seen from some people to add a few gallons of gasoline to diesel fuel for quicker starts and better performance?

My '68 Mercedes 220 diesel also called for a gallon of gasoline per tankful in climates where temperatures could fall below 0'F.
That was to help prevent the fuel from gelling, it also reduced the lubricity considerably but since it was just an occasional thing the increased wear probably never showed up.
But it turns out the real problem each and every time has been that some where some how gasoline has been introduced into the system by mistake.

However Da Book on my 82 Diesel Rabbit explained the use of up to 10% gasoline to assist in cold weather..
no matter how cold it got - and the Bitterroot Valley got really cold - I never considered adding gasoline, or any other magic sauce - it just isn't necessary.

Just a glow plug mechanical engine, nothing fancy.
But that engine had a mechanical fuel injection pump not an electrical high pressure pump like the TDI. Also the pump is not the same on early TDIs. This just started since the 2009 version TDI that meets the new EPA specs. The problem was thought to be the material used in the high pressure pumps so Bosch jumped up with several mods. But when the dust settled it was gas that had been introduced into the fuel and that is what caused the problem.
"So anything lingering in the pipe is sent on with the next product. In gas it isn't' a problem high test to reg or mid range all mix OK. Diesel into gas is not a problem but some time gas into diesel can be. Just depends on how much is there. Vinny"
Years ago, while representing a fuel supplier in court I was shocked to learn that the allowable tolerance for cross-contamination in the tanks was 10%. That was not for the various grades of gasoline, but for diesel - gas.
Many fleets & farmers have been adding filtered waste engine oil to their fuel for decades with no ill effects. I would not be so sure this is a bad idea.
Jet A in a Jetta .. I love that and several of JDs posts (especially #37) has been very interesting. #37 took me WAY back w the Saab and DKW 2 stroke cars. JD do you remember the Javelin Jupiter? Sure glad somebody started this thread.
I read someplace when researching this particular problem that this is not the case in Europe. VW said that the lines from the various tanks run down to the pump directly from each tank and the pump is right at the tank car / truck fill. So in effect the cross contamination is non existent in Europe. But it turned out to be contamination in this country plain and simple. There was one case where the truck driver had dumped a 500 Gal compartment of gas into the service stations diesel tanks by accident.
They did that where I worked once but the other way around. Diesel in the gasoline tank. Every truck (small trucks, vans and pickups) that took on fuel that day smoked and stalled a few miles down the road..............

Not sure... but I think the term "pipe" was meant to mean "pipeline" from refinery to whereever...not at gas stations...although there could be sone comingling there too
When I took a tour of a refinery...they showed large inflatable balls sent through pipeline to separate the different grades of gas/diesel. When asked was there sloshing around the balls and mixing...the tour guide said "yup"....
