    Default Another 2SO Story

    I have another 2SO story
    Just recently came back from a long trip to Kunene, van Zyl's etc. in my Td5... About half way through the trip my lift pump in the fuel tank started screaming like a dying squirrel. Added a bottle of 2SO to the next fill up and no more screaming pump. Funny.

    It will prolong the pump's life due to the added lubricity but it won't "fix" the pump.

    Start saving for a pump regardless.

    There is a cheaper solution somewhere on this forum. I think Discomad posted it - quite recently.

    I was abou t ask what makes this pump so much more special/expensive than the pump a V8 RRC or Disco 1 uses?

    I used to buy an intank fuel pump for the RRC at R400. Pumped at 3....something bar IIRC?

    The latest Car have a writeup on feul and the additives. According to the article Sasol did a test and 2 stroke does not have a measurable effect on lubricity and because 2 Stroke apparently contains heavy metals it damages the injector holes during prolonged use.
    Interestingly Sasol is also the only feul retailer that add additives to increase lubricity.
    I thought I was wrong, but I was mistaken.

    I have no idea. From the article I assume that the test centered around lubricity and injector life.

    Hi All

    it is awesome how some of you guys love to debate in circles, like a dog trying to catch its own tail

    LRWit 2sO in diesel REDUCES smoking compared to the normal running of a diesel motor, especially under heavy load, low revs condition. Now reduced amounts of smoke mean a cleaner more complete combustion. And that is what prolongs the life of cats, DPF's and also what keeps exhaust sensors clean.

    LRWit a dirty partially clogged EGR is a much bigger threat to exhaust sensors on diesel engines than 2sO mixed into diesel at a rate of 5ml per litre.

    I have stocked up on popcorn and I will enjoy following this thread!!!

    Tried to get hold of the VDO pump unit alone from Diesel Elec. but up here in Nam they say its not available on their system. Any other options out there?

    I dont know what test they did but an independant study proved that 2SO adds lubricity.

    Why the hell do we add it to 2 stroke engines in the first place?

    George, it is VERY clear that you are utterly convinced that its safe to use 2SO on Lambda and CAT equipped cars.

    I remain unconvinced BUT I AM NOT STATING THAT ITS NOT SAFE EITHER!!

    So, unless you or whoever present categoric, credible, verifyable, scientific PROOF or reference to such evidence, that 2SO IS NOT HARMFULL to either, I will remain concerned (even if I am the only one to have - and voice - such concerns) about the POSSIBLY negative consequences your persistent recommendation of 2SO might have on those lamba/CAT equipped engines who's owners accept your (and other's) 2SO advice as "good, sound & safe advice".

    So, if I'm debating in a circle like a dog trying to catch its own tail - then its AWESOME!!!

    Since my concerns seem to trouble you - I will hence forth remain silent on this matter. Its no skin off my back.
    Best regards

    You have zero control over the application of the advice regardless of your good intentions.

    I do not believe a Lambda sensor can survive 2SO additives.
    I do not believe a CAT can survive when a dirty system suddenly gets cleaned with 2SO additives.

    I do think it would be wiser to not only punt the benefits, but also point out some possible precautions, regardless of how small they might be.

    Always safer than sorry.

    Sorry Marius, but that on it's own is not an argument. 2SO is meant to be added to petrol used in 2 stroke engines. Petrol does have much lower lubricity than diesel and hence the addition of 2 stroke oil to petrol in 2 stroke engines is essential.

    if you understand that a 2 stroke petrol engine has no sump with oil in it, you will understand why lubrication needs to be added to prevent things from seizing up

    I agree that the magical effects of 2SO are debatable but the fact that it adds lubricity is not debatable. Its a fact!

    I understand 2S engines very well and if 2SO is good enough to lubricate a 2S engine then it is definitely beneficial (even in our low ratios) in terms of lubrication in our diesel engines for the injectors and HPFP..... As proven in the study I posted earlier.
