I called disco george out on this nonsense too, and his insistance that we all need to trickle charge our batterys

I'll take 'lab tests' in the same vain that I take manufacturer claimed mpg figures. What happens in the real world is what matters.
It will certainly be interesting if any response is forthcoming.

What about the zinc on your injector, that sounds painful At work

That zinc stuff seems a little exaggerated...
If in 16 hours the flow is reduced by 2%, imagine the hundreds if not thousands of hours some engines spiked with 2SO have functioned... And not many, if any, have complained of fouled/blocked injectors...
Call me stupid, but why zinc to adhere to the injector's nozzle metal? It's not an electrolytic process... And copper???...

Just adding some balance, I've read the tests and they are by no means definitive, very little substance in the tests and it makes you wonder why a small oil company such as SASOL have done this test and no one else has? There is always a reason, usually financial, we just need to see what it is

I agree with what Alex says. In my experience, I have not seen any improvement in fuel consumption or quietness. However, the MOT smoke test definitely has been improved by using 2SO - from 0.9 to 0.5 on my previous manual, 0.7 on my auto. Therefore, if anything, the injectors have been cleaned, not blocked! 10MY (Sept 09) TD4 HSE Auto in Stornoway Grey (Now Gone)

The idea of the fouling could explain the loss of economy I saw (see earlier in the thread). I stopped adding it after almost 4000 miles driven. Now to see if Millers reverses the drop in economy (as it suggests it will).
Again though, it proves nothing I just reported what I saw

The exaggerated response of Npinks to this "Test" is typical for his past and present attitude to this subject. No further comment from my side.
Unfortunately, the cited test has not revealed the make and quality of the two 2SO used in the test.
YF has not without reason recommended the use of non-synthetic 2SO. I myself use the addition of 2SO to my diesel for more than 10 years with 100thousands of km driven WITHOUT any claimed fouling of the injectors.
On the contrary, the injectors are exceptionally clean, and the bi-annually TUV exhaust test is by more than 50% better than the values demanded by Mercedes.
So what is true or correct? The SASOL 2SO test has certainly substance, but claiming that most 2SO oils contain Zinc and therfor foul the injectors, makes me a little suspicious, especially after the low running time of the claimed period.
Please keep in mind that SASOL is a diesel producer and therefor has a great interest in the underlining that their product is a quality product according to established standards. What they do not say is the insufficiency of those standards due to ever increasing pollution control regulations.
So, everybody should judge on his own, and the polemic, as cried out by Npinks, be please valued with great care.

Interesting "test" I am left as clearly are others why, if the fuel injectors of the engine used were so measurably fouled with zinc, after 16 HOURS of running, why the countryside isn't littered with broken down FL2's (and other makes of car) all with completely blocked injectors after hundreds and thousands of running hours?

There are key themes on this site around the problems that FL2 owners experience that are continually renewed, rear diff failure being one example yet I have not been aware of any threads let alone repeat ones, concerning fuel injector nozzles bunged up with zinc or anything else for that matter.

I am left wondering why the reality doesn't quite seem to match these results? I'm not dissing it - just wondering!

Well Paul you are not and I am entitled to my opinion, a test has been carried out and provded it's not worth the additional effort to add 2SO, feel free to post a test that shows it is worth it, if one exists  Former Mod/Member, with the most post & Chicken George Arch nemesis

One test by a non impartial fuel company proves very little.
The anecdotal evidence of thousands, probably more, of diesel and 2so users must count for something.
SASOL have provided some nice graphs where are the photos of Zinc deposits?
The decrease in fuel flow is interesting but based on what? A computer was controlling the engine, what was the feedback loop? If it was power then the test could almost be indicating that less fuel was needed to get the engine to the required speed commanded by the accelerator, therefore not indicating a blockage but a fuel saving.
Too many variables left unanswered.

Yes, Npinks, you are certainly entiteled to express your opinion. But you have never substanciated your opinion, perhaps due to missing knowledge. To jump to the presented results of one singe (non-neutral) oil company and to dismiss the use of 2SO without considering the positive reports of thousands of 2SO mixer worldwide over millions of driven km or miles does not put your "opinion" in a trustworthy light. You tend to only accept what you want to accept, irrespective the many reports which put your "opinion" in the trash box. So please come down from your horse, as we say in Germany.
And one more thing, Npinks, I do not believe in the benefits of mixing 2SO, I KNOW due to my education and long practical experience.

I don't need to provide proof of whether it does or doesn't work, the fact that the motor manufacturers don't tell you to add 2SO into you diesel is enough for me its obviously not required, but when some people rave on about it been so wonderful do many millions of miles, it obviously isn't doing any harm adding it.

If you care to have read my opinion from day one, it is asking for proof that it does do something good for the engine, nobody has been able to provide this proof, but someone has provided proof it isn't all what it is claimed to be.

It not me on your german high horse either, its those that are using it and dismiss the facts proven that are getting up tight

anyway, until you or your fellow users can provide the proof it actually "helps", I'll enjoy my weekend with the knowledge i ain't wasted my time adding 200ml of wonder elixir to each tank in a vane hope of keeping my engine nice & clean, or spick and span as we say her in good old blighty

ta ta for now old boy, see you over the english chanel for a dog fight when you have the proof  Former Mod/Member, with the most post & Chicken George Arch nemesis
