Surely it would smoke as it does in a little stroker, how ever i can see the benifits as it would lube any moving part as it does in a stroker.
The question is how much do you use and how often?
I wouldn't use engine oil as this would not burn the same way 2stroke oil does and wouldn't mix in the same way.

General consensus is 200:1, and no it doesn't add to the smoke!

About 43 years ago I had a lambretta [ didn't we all] if a filling station didn't have the 2 stroke mixing oil pump I would use a few squirts from the Redex pump which I always thought made it perform better than using 2 stroke.
Anyway i would guess that the use of 2 stroke oil or redex cant do any harm to an engine? Most diesel owners swear by Millers? Similiar product? Could work even better in Petrol engines as at least diesel has some lubricity unlike petrol? Dave

Why not just run your car on biodiesel? It's got a higher lubricity than petro-diesel, it's a better solvent, and it's cheaper. Win/win/win situation and no need for 2-stroke oil

While we're on the subject of 2-stroke, how much fun would a 2-stroke R75 be lol.

Mick,
I agree. There are several pages of comment about this on another Forum and the consensus is that it is beneficial; engines run quieter, marginally more economical and with better lubrication. I'm not technically minded but there is a lot of very informed opinion on the forum and on balance I'm inclined to believe it's worthwhile.
The suggestion is to put 1/4 litre into 50 litre tank immediately before refuelling (as you say 1:200 ratio).
Whenever it's mentioned to service agents though the usual reaction is don't do it because it's not written in the manual and they worry about their warranty. Manufacturers warranty of course is sadly no longer an issue with MGR cars.
I'm going to try it in my ZT-T CDTi and I'll let you know if it improves, explodes or disappears in a cloud of smoke.
Anyway everyone.

Mick, if it helps any, I had to replace the mechanical fuel pump on my BMW 525tds at around 135k miles. As this was costing £600 for the pump only I thought it prudent to ask the diesel specialist (Lawson Diesel in Edinburgh) what kind of additives I might use to ensure longer life of the pump (not that I was going to run the car for another 135k but I was interested). They basically told me not to bother with additives but to pour a small amount of engine oil into the tank with every second or third full tank of fuel. They didn't specify any particular amount. I ended up, IIRC, pouring in about a quarter of a 500ml bottle of Tesco or such like oil on every third fill-up. This was obviously further diluted with fuel top-ups between fill-ups.

I can't say I noticed any more smoke although the motor was "black-boxed" and smoked under heavy acceleration anyway. Also, I didn't notice the engine being any quieter although at that mileage I wasn't expecting miracles anyway. I don't remember any problems or even thinking anything like " I wonder if that's because I put oil in the fuel". Nothing!

I haven't used this method with the ZT as I am always that bit more wary with newer technology but I do use Millers treatment.

Hopefully this helps a little.

found this on another forum I'm not going to do it I just thought id show everyone


to all interested:
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%.


and more :-
You may all know that Mercedes Benz have conducted in 2007 a long distance reliability test with a number of Mercedes E-Class 320 cdi from Paris to Beijing. Due to the fact that the diesel quality in East European Countries, Russia and China does not meet the DIN requirements, and Mercedes did not want to take the risk of their engines to flopp due to lousy fuel, the total tour has been accompanied by diesel tanks to re-fuel the E-Class cdi's. Selected members of the Mercedes clientele could apply to participate in selected parts of this test-tour, and advocats and notaries had to certify the correctness of this long term reliability test.
Although Mercedes does not like it published or made public, it is a fact that the diesel-fuel used for this test did contain 2-stroke oil to grease the high pressure pump components and to keep the engines clean during this marathon.
Why our car manufacturers do not officially allow the homoeophatic addition of 2-stroke oil to the diesel fuel has many reasons, mostly of legal nature. Besides this, which car manufacturer has any interest in excessive reliability of their engines? Their repair shops will have great problems.
Meanwhile the "2-stroke-oil to diesel" issue has attracted the interest of a number of Universities in Germany, as this 2-stroke oil has shown to have amazing poperties if added in a small dosis to diesel fuel (1:200), especially the positive impact on air pollution, reduced fuel consumption and improved long term reliability of the diesel engine. The pro and con discussions will go on for a while. But as soon as an accademic report has been published by one of our Universities, this will change very fast.
By the way: all car manufacturers reject the addition of any fuel "additive" in their cars, and warn that guarantee MAY be affected. Nobody says, that guarantee WILL be rejected. 2-stroke oil in its properties is not an additive, as you add oil to oil if you "dope" you fuel with a dosis of 2-stroke oil. The dosis of 2-stroke oil in your diesel-fuel is very difficult to analyse, as every (chemical) analysis has the main function to identify substances which are harmful. But 2-stroke oil has proven not to be harmful at all, on the contrary!
Personally, I use 2-stroke oil now for many years in all of my diesel cars (my present business car is a Mercedes 320 cdi DPF Automatic). And I never had any problems whatsoever.

Thanks for the input guys.

Paul, that's a very interesting bit of info there.
Unlike you, I am going for it!
Will search out some JASO FB or better, mineral only, and give it a try.
