Diesel Additives and the HDi

[fred1]

Hi.

Interesting posting by on the "Freel2.com forum concerning recent investigations by a "well known" German car manufacturer. The posting was spotted recently by a C5-L forum member. See below:-

"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%."

Food for thought!!!

Can you reveal the source or location of this article please?
I work for a small independant lubes manufacturer and feel sure this could be a great "new" addition to our range, assuming the source is reliable.

Hi,

As I said it was a post on the Freel2.com forum, link to the post below.

Been putting a drop in my c5 hdi for about a year now.

[poggle]

does anybody think i would be able use this instead of Eolys oil in my 2.2 hdi its a lot cheaper to buy

No. The Eolys is there to reduce the temperature at which the particle filter burns off the trapped particles.

From reading this post the 2-stroke oil is being used to add lubricity to the diesel so as to prolong the life of the moving parts in the pump and injectors.

I agree that it prevents DPF from clogging.

1. Clear codes with obd2 if in limp mode.
2. Inject 2 bottles of DPF cleaner through oxygen sensor hole. Forced regen can damage DPF.
3. Disable start/stop, especially on long rides when you want passive regeneration heat to be optimal. Don't drive with very high rpm and low speed because DPF feels smoked and choked. Instead keep high gear and high speed for high cleaning airflow through DPF.
4. Pour into almost empty tank 2 stroke oil (ISO EGD/JASO FD quality). You say 1:200 ratio. I did 1:120 ratio, 500ML and then full 60L tank. Citroen C4 B7 immediately was running smoother, quieter and with noticeably more power.

There is no need to change my car's DPF but there is a programmed problem which says that DPF has already reached (only 10 years old car) end of service, therefore has to be changed. But the DPF is working good, I want to clear that stupid error code.

"P1445 Additive adding. The quantity of injected into the particle emission filter has exceeded the maximum threshold. The particulate emission filter must be changed."

This guy has same error even though his car works well, viewtopic.php?t=67830

Well this appears to be a real blast from the past

Original post is from before I joined this forum in 2013

The original link has expired but the above content has survived ....interesting to see your endorsment frer8833 and I have some 2-stroke left over from my X7 days

@Skull:

It'd be fun to know if you get improvement

@Paul-R:

Thanks for finding the wayback link, it has 87 pages
https://web.archive.org/web/20161021110 ... ic878.html

My summary of the first ten pages is,

A. Up to 1 litre of 2-stroke oil (low ash) before full tank, or 1:50 ratio, is safe (recommended initially for heavily sooted car). One person used 500ml like me and liked it. The regular maintenance amount is 300ml.
B. Cetane points is increased by 3-5 for a smoother combustion. TSO burns cleaner than diesel.
C. Soot in exhaust is reduced by 50%. Quieter, smoother, torquer, improved cold start.
D. 2-stroke oil protects turbo from soot and metal particles.
E. On average 5% better mileage. One says 10% (30+3 mpg)
F. Biodiesel is aggressive for pump etc but 2-stroke oil is lubricating but is still not considered an additive because it is almost same as diesel. (The one I used is blue dyed).
G. Someone added TSO for years without any damage. Gets more power uphill.

"I myself use the addition of 2SO to my diesel for more than 10 years with 100thousands of km driven WITHOUT any claimed fouling of the injectors.
On the contrary, the injectors are exceptionally clean, and the bi-annually TUV exhaust test is by more than 50% better than the values demanded by Mercedes."

Soon, at a petrol pump near you....

Stuff always come back even if for a differing reason

My summary of the first ten pages is, ...

I'm only on page 6 but considering ....

Using some FB grade 2T on my HDi Xantia (1999 non-DPF)

Using some FC or FD grade on my Daughter's KA TDCi (2011 DPF) when and if I inherite it in due couse ...

[frer8833]

My opinion now is that 2 Stroke oil is for power/torque, fuel economy and cleaning injectors but it's not for decoking the DPF which is better done with 125ML of Mecarun Eco 10000 Diesel to a half tank of diesel. I did 125ML first, but after I added a few days later, without refuelling, 125ML more + 20ML of C99 the car woke up like a sprinter horse.
