    Default 2 stroke oil in diesel?

    Hi!
    A friend sent me this article- what do you guys think?
    Anybody want to start a 2 stroke diesel additive product with me?

    http://www.freel2.com/forum/topic878.html

    ....due to the pollution control measures of the EC diesel-oil is nearly sulphur free and contains up to 5% of bio-diesel. Sulphur has the property to grease the high pressure injection pump and the injectors. Without sulphur, the reduced greasing property of the new diesel has already shown negativ impacts on the long-term stability of the injectors and the high pressure pump. 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 (sulphor contained) diesel.
    The engine-research centre of a well known German car manufacurer has conducted some long term tests of diesel additives to find out whether any one of them will have an impact on the long term reliability of the diesel engine components. This introduction to explain were my information comes from.
    The results of this research: any diesel additive of any manufacturer presently on the market is not worth the money!
    BUT: 2-stroke oil, which we use in our motor saws, lawn mower or in 2-stroke motor engines has shown to have an extreme positive impact on diesel engines, if such 2-stroke oil is added to the diesel in a homoeophatic dosis of 1:200. 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 burnes 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 clogg, and the "burn free" process of the DPF will be much less.
    One more information: in Germany we have to present our cars every 2 years to the TUV -Technical Supervision Organisation - who will check, amongs others, 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 milage by 3-5%.

    I add 200ml/65l tank every second tank. Been running like that for 60 000 km and no probs so far!

    Being the ever critic.
    1) The Yamaha guy supplies no link to the source of this info.
    2) He uses big words. "homoeophatic" is not a word.
    3) He can't do math. 1:200 on 70l = 350ml, not 0.300 litre.
    4) TUV afaik is a quality assurance certification organisation like ISO. I don't believe that do any kind of scientific testing. But I could be wrong about this and stand to be corrected.
    5) Cloud-factor? and a number with no unit.

    Anyone here actually tried this and can confirm/deny by own experience?

    Default already covered

    Thanks scotty's!
    I see there was a huge chirp on the subject already.
    I'm an additive junky- even use HP sauce on my eggs!!(steady now)
    So...seeing as I'm a SASOL diesel fan...I'll be chucking in the 2 stroke additive!

    This will be an interesting one. A D4D that is running a 2 stroke additive. What mileage on your car now?

    As I said. This will be a nice test case. I know you change your diesel filter regularly and now you are running 2-stroke as well.

    Commonly the D4D's have problems with the injectors from about 50,000km.

    If this is a cure, I would love to hear TSA's response.

    I've been running 200ml on every tank (40L or so) for a while now. I can positively say that the engine is smoother, seems a little quieter and I am actualy getting a few km more per tank. I agree that the low sulpher diesel is not good for my Bosch VE pump and the 2 stroke makes up for that and keeps the engine and injectors clean. The new common rail engines are designed with the low sulper in mind but I'm sure 2 stroke will also do these engine's some good.

    This is very interesting indeed, and it makes sense as well. I hope it works.

    My Fortuner also has 60 000 km on the clock, and has never had any two stroke oil added to the diesel.

    Maybe mine can be the control test for Uys's vehicle?

    On the other hand, maybe it is safer for my pocket to just start adding the 50-juice?

    Correct. I don't go more than 20k km on a filter.

    I don't believe that adding the two stroke will improve fuel consumption, BUT, I can see that is does when I do add it. My fuel consumption is better by about 0.5 km/l on every tank that the two stroke is added to.

    By adding two stroke oil the lubricity of the diesel is improved which 'eases' the mechanics of the injection system and probable improves the spray pattern from the injectors. This will improve the efficiency of the combustion process thus providing more power/fuel quantity or less fuel /power requirement. Both equates to reduces fuel consumption.

    Hi, Redliner.

    I'm aware of cloud TEMPERATURE - this is the temp at which diesel fuel starts to experience initial thickening / waxing.

    I've NEVER heard of the term "CLOUD FACTOR" when referring to exhaust emissions.

    Exactly what I was thinking. When the wax starts falling from solution at low temps.
    But I just get the feeling this guy is plucking terms and big words from a dictionary and mixing and matching terms as he goes along.

    I have tried 2 stroke on my last two tanks and the current one is running low sulphur without additives to compare. The fleet statement did show and improvement over the last two tanks though.

    As for the performance and sound its TOTALLY subjective but somehow in my mind it feels smoother through a longer section of the rev band and quieter (on an already pretty quiet diesel motor).

    I hope it works without side effects though i have only a few months on my warranty left.

    I've seen and heard plenty stories on this topic, but I'm still not entirely convinced.

    One thing I'd like to add is that I've had this discussion with guys in the US on the ClubTouareg forum as well, and some of them add 2-stroke to their V10's. However, there's a big difference in their fuel specs. Over here, we have what we call LSD, which is 500ppm and ULSD which is 50ppm. It seems that in the US and Canada, their LSD is 50ppm and their ULSD is 15ppm. They seem to be of the opinion that you don't need to add 2-stroke if you run on 50ppm diesel.

    They also have various blends of Bio-Diesel and they add stuff to that for various reasons as well, but that doesn't apply to us... yet...

    Just m2cw.

    Andrie,

    Have you tried it?
