2 stroke oil in diesel...anyone tried it?

I miss-fuelled the Toyota some months ago, 60 litres of unleaded gone to waste!
Re-filled with diesel and added some 2 stroke oil more to lubricate the "cleaning" effect of the petrol.
The Toyota is a forward control vehicle and you are very aware of the engine noise - which I did notice less of with the "additive". My father-in-law, a diesel mechanic, swore by it! I think I'll give it a try in humpy.

It needs to be MINERAL 2 stroke NOT Synthetic: 200:1 It is recommend for miss-fuel cars where petrol has been drained form diesel tank:

"
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 mileage by 3-5%."
 
Thanks Lukas for the above info. Very helpful although I don't suppose you know/able to say which German car manufacturer.....?! having forgotten to add to my previous tankful really brought home the improvement and benefits.

I too find around 3% mpg improvement too. Next challenge is how do i get my wife to use it in her Toledo other than add it myself when I think she has filled up?

I was telling a friend of mine about this a couple of weeks ago who runs a Xtrail diesel and is pretty well genned up on engines etc but he thinks this is nuts and will coke up the engines!
 
Put the 2 stroke oil in and the difference is very noticeable. As others have said, it's very much quieter and the usual slight vibration on tick over has disappeared altogether.
Too early to say anything about fuel economy, but on smoothness alone I'm converted!

Ok - I'm going to give this a try.
Which 2-stroke oil is recommended?
Where from?
How much to put in a 42l tank at fill up?

I'm just wondering about the 2 stroke oil,sounds good but wont it knack up the CAT?

...Or coke up the engine as mentioned previously? People seem to be reporting universally good results, but is this short-term gain for long-term pain!?

I've bought the cheapo 2-stroke oil from Tesco/Asda as it is mineral based
I started using it at 150:1 and have varied it from 200:1 to 100:1
I'm happy at between 150:1 and 200:1

200:1 for a 40 litre fill up is 200 ml

I talked with some Aircraft engineers this week and they agree it will be benificial but the amount of 200-300 mil seems very extreme,they were talking a few capfulls and that was just to lube the pump and injectors.
The mpg wasnt worth it they reckoned if you would create expensive damage later on.

so that and some millers then :)
 
I think there are two things being done here.
1) lube the pump seals
2) increase the cetane rating of the diesel

50ml will do the first one and 200:1 will do the second.

With regards the long term damage, why should there be any.? The mineral oil is still light enough to burn cleanly. And as someone said recently we should all give our cars an 'italian tune' every now and then.

it depends if the amount of 2 stroke oil is excessive and reaches the cat on the exhaust.
A2's seem clean enough anyway so unsure if there is a way they can tell the cats gassed or not.
 
I'm going to give this a try next time I fill up, will get hold of some 2 stroke oil, I may even have a spare bottle left over from my scooter :)
 
Can anyone recomed an oil & how much should it cost, I've had a quick look & it seems to be around £10 a litre
 
better not use my semi synthetic silkoline for my vespa t5 then will try the stuff for my petrol strimmer, i guess thats mineral
 
Hi. I've been mixing 2-stroke oil with Diesel for several years for the 1.4 TDI and fully recommend it to any PD Diesel engine user (also to any Common Rail engine user). All benefits have been listed already here. In Germany especially Taxi drivers swear by adding 2-stroke oil to their diesels.

The best positive effects ("quiet" engine + lubricating/cooling/cleaning the injection system + lower fuel consumption) are achieved by mixing 1:150, meaning 200 ml into a 30 l tank.

Be sure to buy only semi-synthetic oil featuring the combined specification of

API TC + ISO L-EGC + JASO FC​

since that type oil generates virtually zero % residues while burning. Please don't take L-EGB or L-EGD or others...
