two stroke oil in the diesel ?

[linus]

This one is new to me (probably already discussed here )but somehow sounds good to me: every time you fill up your tank adding some 2stroke oil (+/- 1:250)
Anyone heard of this, or adding regurarly 2strokeoil ?

Why would you want to do that?

Why would you want to do that

Well....On many german internet pages i have read that it makes diesels (especially common rail) start and run smoother and it should lubrificate the diesel pump. Many of the 2stroke oil users swear on it after hundreds of thousands of KM. They swear also that there are no negative effects on the engine at all.

I dont know but it might be true

Someone correct me if i'm wrong, but does'nt diesel have it's own lubricating properties

[Red Tranny Cann Man]

Pretty sure diesel is already a lubricant, but modern diesel has aparently got less sulphur in now-a-days so therefore is not as good at lubricating as older stuff.

Think I might leave the 2-stroke out tbh, a general rule for anything regarding fuel is that if the big refinery companies are doing it to make money, then its worth it.

linus have you any english language sites on the subject ?

[Gavin]

modern 2 stroke oils have lots od dditives and detergents and catually keep the engines very clean, it may be that putting it in a diesel helps keep it clean too

Ifound this with a google search:

The first message explains the (possible) benefits of adding 2stroke oil:

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%.



On german forums i found treads with over 50 pages on this argument...:

I took a 1958 Gardner engined bus to Germany and Sweden a few years ago. It ran fine on German diesel but as soon as it was running on Swedish diesel it kept stalling and was difficult to start. It was obviously something to do with Swedish clean diesel and the only way I could get it to run was to put engine oil in to the fuel tank with the diesel. This was advised to me by a local classic truck enthusiast who saw me stopped across a road junction!
I put at least 5 litres in each time I filled the tank up and then had to adjust the engine idling speed to get it to run. Whether it was a good thing for the engine and fuel asembly I have no idea but it certainly helped me to finish the contract and bring the bus back to the UK. The smell of Swedish diesel fumes is very sickly sweet, I presume its bio or rape seed or similar?

Interesting. Worth looking into some more

[jolly olly]

This has got me very interested in trying it out two, after reading through the link thats posted.

[Backbone of Britain]

Very well explained, worth looking into me thinks.

[jolly olly]

After going through all the posts it seems to look promising but i would like to see what comes back with the studies thats supposed to be going on.

[painter4]

i have some shell advanced 2t oil i used for my go kart but i think its mineral based is this ok to use ..

[jolly olly]

Just copied and pasted this from the other site hope it makes sence to some one, so if your brave enough to try it let us know the out come.

The quote.
I would use any of the two 2-T oils, whichever I would get cheaper.
You can also use the Mobil Extra 2T.
Important is, that those 2T-oils should comply with JASCO "FC" or ISO L-E "GC" or "GD", which should be written on the bottle. All 2T-oils as per these norms burn with an ash content of less than 0,05%.
