    Nope. 2so cant fix mechanical issues. We use it for extra lube and to keep carbon deposits at bay.

    If you always have good diesel and your engine and driving style arent prone to carbon buildup 2so will have almost zero effect.

    And this is the logic I have trouble getting to terms with.

    Scientific proof is presented that you are at best just wasting money, and now suddenly shift the reason to the diesel. Because, SA has the shittest diesel according to you...

    Quick summary:

    HFRR test results: 2SO improves lubricity in Market Diesel

    SLBOCLE test results:
    2SO improves lubricity in Market Diesel, Refinery Diesel and EN590 diesel

    Cetane Number: 2SO improves Cetane levels in Market Diesel


    Zinc Content: all dosed fuels are under 0.3ppm, far from the boundary value : "Zinc levels as low as 1pmm in diesel can cause severe injector fouling"

    To go to the "Conclusion":

    CONCLUSIONS

    Based on the results of this study, the following conclusions are drawn:
    • At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel lubricity.Not true. See above.
    • All diesel fuel sold in South Africa has to meet the SANS 342:2014 lubricity specification to ensure the proper protection of diesel fuel pumps and injector systems.Can't dispute a law
    • The low sulphur diesel products sold by Sasol contain lubricity improver additives which are far more effective than 2-stroke oil.Show tests
    • At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel cetane number.Not true, a Cetan difference of 1 point is not insignificant, that's 2%
    • No measurable effect on all other regulated diesel properties was measured at a 200:1 dose of 2-stroke oil in diesel.Very interesting: no issues detected regarding the use of 2SO: "Exhaust emissions of the Market Diesel were compared to a 200:1 blend of Market diesel and 2-stroke oil. The test was repeated three times for each fuel and the average results were compared. The results showed that the 2-stroke oil had a negligible effect on all legislated emissions (Carbon Monoxide, Hydrocarbons, Nitrogen Oxides and Particulate Matter (black smoke)). There was also no evidence of any visible smoke. The fuel consumption over the test cycle was also unchanged. This is in-line with expectations as 2-stroke oil is a light oil such as diesel, so small amounts should have no marked effect on emissions from a diesel engine."
    • 2-stroke oil can contain around 16ppm zinc, or higher depending on the formulation and batch.So what, so does engine oil present in your engine and which is present in your combustion chamber.
    • Trace amounts of zinc in diesel are known to rapidly accelerate injector nozzle deposits.Incorrect: >1ppm is known to have an effect
    • Engine test results show that a 200:1 blend of 2-stroke oil in diesel results in a 2% loss of engine power in a 16 hour test due to injector fouling, a risk that would apply to any common rail diesel engine, but could also worsen fouling in older engines.This contradicts the following: "The fuel consumption over the test cycle was also unchanged." The test was an artificial zinc fouling test and has no relevance to a 200:1 mix
    • Vehicles fitted with a diesel particulate filter (DPF) in the exhaust system could experience reduced DPF life due to the collection of ash and metal based contaminants in the filter over time with the continued use of 2-stroke oil."Could" not WILL. See the following: "
      The results showed that the 2-stroke oil had a negligible effect on all legislated emissions (Carbon Monoxide, Hydrocarbons, Nitrogen Oxides and Particulate Matter (black smoke))". Please explain the CLEAR contradiction between the Conclusion and the body of the test.

    As I said: I'm not sold. The study conclusions are at variance with the test results. Unfortunately, as in any REAL test, no actual numbers have been shown, just vague graphs. This is so contrary to good scientific practice, it's actuially laughable.

    Show me where I said we have the shittiest diesel.

    I use it because it was designed to lube and lube is crucial in a diesel engine. And i use for its carbon cleaning properties. I have seen it enough times with own eyes on various vehicles in the REAL world to be convinces thereof. I doubt any LAB test will convince me otherwise unless im there to witness it.

    Nobody has answered my two fundamental questions.

    1. With all the hype around the subject, why was no third parties invited to witness/partake in the sasol lab test?

    2. Why is the internet not filled with negative reports of 2so use?

    Yes, in a 20:1 mix in petrol engines.

    Are you willing to shell out 250k for this test? Not? Oh...

    2. Why is the internet not filled with negative reports of 2so use?

    Its filled 50:50 with results of believers, and people that sais it does nothing. The reason you dont see negative results, is because you ninja google for positive results on the subject. Go passed the first 20 hits for a change.

    Btw, its only my FIL that sais you will run damage using 2so.

    The rest of the world that is against, sais your wasting money and pollutes our air.

    Hype? In your earlier post you said thousands, that's hardly "hype" considering there are 7 billion people on the planet. I'd guess that the "hype" is mostly here, and also why would Sasol do that? You don't see drug companies inviting people to watch them test their drugs, it's just not done that way, you know it! You can invite who you want, there will always be some idiot that says, I wasn't there so it can't be true.

    Well because like my statement above, 99,9999999999% of the driving population in the world don't use 2So, and don't care to tell the whole world that it doesn't matter to them. It's the 2So guys that want to tell everyone what they're missing, noone else cares...

    I doubt having two or three third parties will cost extra at the lab test......unless they find results showing that 2so is beneficial. Then it can cost sasol billions.

    Show me 10 bad reports online. I can show you hundreds of good reports.

    Do people complain or praise mostly online?

    No hype? Why is thread still going after how many pages?

    Have you seen how many forums around the world discuss this very topic?

    If there is no hype why did sasol do the teat? Why did magazines write articles?

    Yeah, no hype at all.

    Just because you see this as hype, and think that a couple of thousand people think it's hype, hardly makes it hype in the global scheme of things. I still stick to my previous statement, I used it for almost a year, it did ZERO for my car, only an insane person would continue wasting money on something that does zero for them. Thus I stopped...

    Hang on. It did zero for your car? So the sasol test is wrong then? You should have had blocked injectors or worse performance according to them?

    Im confused now, are you pro or anti 2so?

    Impartial means it does nothing which contradicts the sasol test.

    I want bad reports.

    Heres a result.

    2so made my back bumper plack. Thats it. It did nothing more.


    Is it bad or impartial?

    Impartial is a result as well.


    God I can't believe I am even trying to explain how results work, to someone that can't grasp the consept of results...

    Ok, I just realised something. Please continue to use 2so.

    If you don't, and the sales drops to low, the companies making 2so will have no reason to produce it, and I will have to chuck my edge trimmer in the bin...

    I dont see how SASOL could "loose millions" if the proof was that 2so turnes diesel into a better product.

    On the contarary. They would then have market advantage as the first to dose diesel with 2so "to lubricate and clear carbon", something the well researched diesel fuels of all major petroleum companies apparently does not do...

    One downside of 2so which I will admit is that 2so increases the sulphur ppm. I calculated it to be about 15ppm increase iirc.

    It cant be that bad if my engine oil stays golden for thousands of km after service. This is 400km after my last oil change.

    Legislation wont allow such a blended formula even if sasol wanted to produce it.

    I also dont understand how my injectors are still fine after all this use? Sasol determined i should have had failure ages ago.

    Really is a deurmekaar topic ne?
