The pump manufacturers have tried to react by lining the moving parts of the pumps with Teflon or other suitable material. However, the long term stability is still not achieved as with the old (sulphur contained) diesel.

In practical terms: 0,300 litre of 2-stroke oil into the 70L diesel tank. The 2-stroke oil will be absorbed by the diesel (emulsion) and grease every moving part of the high pressure pump and the injectors.
Besides this, the 2-stroke oil will keep the diesel engine clean, as it burns cleaner as the diesel itself. In other words, the 2-stroke oil has a much lower ash-content as diesel, when burned. This proven fact delays the DPF (diesel particulate (soot) filter) to clog, and the "burn free" process of the DPF will be much less.
One more piece of information:
In Germany we have to present our cars every 2 years to the TUV -Technical Supervision Organisation - who will check, amongst other things, the pollution of petrol and diesel engines.
The measured cloud-factor of a diesel engine without use of 2-stroke oil has been 0,95. The same factor with the use of 2-stroke oil has been 0,47 - reduction of nearly half of the soot particles. Besides this, the use of 2-stroke oil in the diesel will increase the mileage by 3-5%. and more :-
You may all know that Mercedes Benz have conducted in 2007 a long distance reliability test with a number of Mercedes E-Class 320 cdi from Paris to Beijing.
Due to the fact that the diesel quality in East European Countries, Russia and China does not meet the DIN requirements, and Mercedes did not want to take the risk of their engines to flop due to lousy fuel, the total tour has been accompanied by diesel tanks to re-fuel the E-Class cdi's.
Selected members of the Mercedes clientele could apply to participate in selected parts of this test-tour, and advocates and notaries had to certify the correctness of this long term reliability test. Although Mercedes does not like it published or made public, it is a fact that the diesel-fuel used for this test did contain 2-stroke oil to grease the high pressure pump components and to keep the engines clean during this marathon.
Why our car manufacturers do not officially allow the homeopathic addition of 2-stroke oil to the diesel fuel has many reasons, mostly of legal nature. Besides this, which car manufacturer has any interest in excessive reliability of their engines? Their repair shops will have great problems. Meanwhile the "2-stroke-oil to diesel" issue has attracted the interest of a number of Universities in Germany, as this 2-stroke oil has shown to have amazing properties if added in a small does to diesel fuel (1:200), especially the positive impact on air pollution, reduced fuel consumption and improved long term reliability of the diesel engine. The pro and con discussions will go on for a while. But as soon as an academic report has been published by one of our Universities, this will change very fast.
By the way:
All car manufacturers reject the addition of any fuel "additive" in their cars, and warn that guarantee MAY be affected. Nobody says, that guarantee WILL be rejected. 2-stroke oil in its properties is not an additive, as you add oil to oil if you "dope" you fuel with a doses of 2-stroke oil. The doses of 2-stroke oil in your diesel-fuel is very difficult to analyse, as every (chemical) analysis has the main function to identify substances which are harmful. But 2-stroke oil has proven not to be harmful at all, on the contrary!
Personally, I use 2-stroke oil now for many years in all of my diesel cars (my present business car is a Mercedes 320 cdi DPF Automatic). And I never had any problems whatsoever. " ............................................................................................

Well I have maintained small mixed diesel fleets and never used it or any other additive in the tanks. Just good filtering and maintainance.
Now looking at this statement "the diesel quality in East European Countries, Russia and China does not meet the DIN requirements" I might not disagree with it but what has 2007 diesel from those countries got in common with Australia in 2019 ???? Not much I believe.
It is amazing what you can find to justify things on the internet. But probably not doing any harm. Just do not believe those claims about any of it really and the DPF :

While I can understand the argument about the 2-stroke lubricating the fuel pump and injectors (although I've read it's more complex than this, and is only a benefit for certain types and makes of diesel fuel systems and not others), I'm highly dubious about the second half of the claim that it actually burns cleaner than pure diesel.
How many of us can remember going to Asian cities when all the motorbikes were powered by 2-stroke engines, and the clouds of smoke they produced! And I still remember having 2-stroke boat engines, and there's nothing anyone can say to convince me they burnt cleaner than today's 4-stroke ones!
But those two examples are petrol engines, so maybe diesel is different - right? Well, consider this. A small amount of oil does find its way into the combustion chambers of modern diesels already - it comes past the piston rings from the sump. My understanding is that this is seen as a bad thing by auto manufacturers because it raises the emissions they are trying so hard to reduce, and it can clog the DPF filters because it causes MORE ash, not less. That's why engines with DPF fitted specify a low SAPS oil, to reduce the effects of the DPF being clogged from the residue of burning even small amounts of lubricant oil.
As for the third claim that it increases fuel efficiency by 3-5%, now I think it's just going into the realms of the snake oil salesman, but I'm going to give the usual disclaimer that I'm not an expert on these things, just thinking aloud!

I have to agree with you Mamil.
It's like back many years ago when I was a test driver in the automotive industry, we often had people making claims that they had bolted some other carburetor to a car and were getting large gains in fuel economy. Never mind that the manufacturer had spent large sums flow metering and testing various carbies to arrive at the best one and settings for that particular engine. If it were so easy that you could pull one off the shelf and get immediate improvements every manufacturer would be doing it. We put a few of these claims to physical test and not one of those we tested lived up to the claims and in fact were worse than the original specs. Hence I treat most of these claims with great scepticism.

Unfortunately engineering is underpinned by accountants and their veiw of economics.
My experience is that older diesels benefit from adding the oil, my 35 year old Volvo smokes less on startup, runs smoother, quieter and is perhaps a little more pokey. Perhaps.
Not sure if it assists the diesel heater much as I suffered a string of issues after adding to the main tank. Probably coincidence, just sayin'.
Modern high pressure diesels get no benefit at all.

A good mate of mine was a Caterpillar field service engineer and spent his whole working life with CAT. His advice to me when I got my first diesel was to always have clean oil, clean fuel and change the oil and filters regularly. His advice regarding additives was long and colourful and boiled down to DON'T.
More advice from him was, when working on cars was to always throw away used fasteners and replace them with new ones and to always use a good accurate torque wrench. It seems to work as my old Series III diesel lasted over a million km's and my current Td5 has over 400k km's on it. Neither car has suffered any failures apart from normal wear and tear (clutches, alternators, etc)

l have a 1990 1HZ diesel motor now with 400 000 k's. Have been putting 330ml ( old engine oil flush bottles with long neck) mineral based 2 stroke oil per tank (penrite green keeper oil) for over 5 years. No pump issues, runs fantastic, cold starting with in 1 crank, no injector issues. Never had a problem. Mate has an 80 series 1HZ was sceptical and has seen me use it all this time, finally convinced him to use some, with in a week noticed better idle, economy, and starting etc.. What convinced me, l had an old (20 year)Victor lawnmower (as we all did), decided it probably need new rings etc. Once l opened it up, no sludge or carbon build up, so basically after 20 years clean as a whistle!!! And lets face it we were not always kind to our mowers. So the 2 stroke oil keeps things lubricated and clean.

After having to pay for a complete pump rebuild on the Hino with only 135.000km on the clock at the time, I'll be adding the 2 stroke oil with each tankful. Clouds of black smoke gradually getting worse and worse was bad enough, but the failure in the governor restricting us to 70km/h at best all the way back from Perth was the last straw. When the pump mob pulled it apart it was very warn and we were told it was common on early model pumps with the change to low sulphur diesel. Who knows, but the cost of the pump rebuild would have bought a lot of 2 stroke oil.
