I put 25ML in our fiesta 1.6tdci on a fill up & its sweet & very quiet.
It made it very quiet , especially on acceleration & improved the economey after the third fill. It also reduced smoke, whilst only visible at night in headlights of cars following its reduced it to virtually zero.

About 300ml per tank of diesel. Seems to make a difference in noise, and smoke.

I think you missed a nought off Mr McP - its about 300ml to a tank full

I think he means 350ml per 70L if 1:200

i put supermarket diesel in, with the occasional premium branded fill up.

it makes a no difference adding anything else than that, 2SO is nothing but a unproven fad, backed up with absolutely no data what so ever, apart from numerous people who put in and and think they are benefiting because there car hasn't broken down, were as it quite possibly wouldn't have anyway.

Effects of 2t oil added to diesel cars.

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 negative 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 (sulphur contained) diesel.
The engine-research centre of a well-known German car manufacturer 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 homeopathic doses 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 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.
More information: in Germany we have to present our cars every 2 years to the TUV -Technical Supervision Organisation - who will check, amongst 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 mileage by 3-5%.


There was also pictures of a 2.5TD engine that had covered 170000KMs with TSO added and it was virtually spotless when stripped. Now if it reduces emissions its going to run cleaner and be more efficient.
From what I have seen its done a cracking job on our Fiesta.

Sadly with our FR2 having been so unreliable I Dont add TSO to that as I do not want to effect any warranty

With a totally empty tank maybe, i don't let it get that low.

That is quite a weird remark to make "Pinky". I, for one, noticed a difference with the sound. I can understand you choosing not to use it yourself but can not understand attacking those who do!!

I dont and have never attacked anyone who does use it, or promote its "benefits" All I have asked for is proof, but even though they had all this data and how some manufactors said it was safe, they could only repeat their statements with out facts

But I also did try it with my old car over a fair few tanks full, and found absolutely no difference, no mpg improvement, noise just the same, then decided my warranty was more important on unfounded fluids been shoved in the tank each time I popped into the petrol station.

It might benefit the engine slightly, so they say, waste of time and money IMO, if it was a wonder elixir then the proof would be published.

I think that I would want to check with the manufacturer of the 2-stroke oil what its sulphur content was (if any) before putting it into my fuel tank. Sulphur used to be very much a by-product of the refining process with fuels, and the additional refining-out of this is partly why lubrication has suffered in ultra-low-sulphur fuels.

It is not the DPF that will suffer directly with the presence of sulphur, but the catalyst brick will poisoned outright by the presence of sulphurs in the exhaust gas streams. That will, in-turn, cause the DPF component to fail, as the passive catalytic temperatures that would normally be achieved under higher engine loads (motorways, A-road hills) will be more difficult to attain, and that means the DPF will not light-off anything like enough to stay clean.

I think that it would be worth someone with some oil-industry experience to ascertain that the 2-stroke oils on sale in Europe do not have any significant quantity of sulphur left in them. The man who makes his living fixing Landrovers will never go hungry.

I don't have a DPF on mine being an 07 model but what I do have is fuel pump paranoia. There are documented occasions of early fuel pumps seizing and trashing it's drive camshaft....not nice! Anything that has the remotest possibility of increasing the lubricity of modern diesel fuels therefore gets my vote! John

Oldgeezer's post above is post number one in http://www.freel2.com/forum/topic878.html, a topic which became quite heated. Read it and make up your own mind. By the way, I'm also well out of warranty and am lucky enough not to have a DPF.
