still no "official Proof" been provided though

You are of course quite right Mr Pinks. If there was "official proof" there would be an outcry about the quality of diesel fuel. However, there seems to be a growing body of acceptance that there is an erosion of the lubrication qualities. For me this was confirmed by a guy I know who is a technical manager with a leading oil company. He admitted to me that this was the case but would not say it publicly due to the disquiet this may cause. They are under great pressure to produce fuels that have less and less emission issues and something has to give. Bizarrely he admitted that he put 2 stroke in his company car!...the world is going mad! John

What sort of 'official proof' do you want and who from???

Do you think fuel companies are going to admit to producing poor lubricating fuels that should have additives put in by the customer  2002 Honda VFR800

thats the point, fuel companies won't admit there is an issue with the fuel

so a independent lab could check out this claim, the OP also stated a couple of car brands had stated they have tested it, but not an ounce of documentation to back it up, not that i had searched for it since

There are universities that have spent thousands on why milk makes corn flakes soggy, but not one has published the 2SO benefits, its all hearsay from a garage/users and its alleged benefits, its obviously not doing any harm, as there would be numerous breakdown related threads on the internet, but is it actually doing any good?

If your confident it works then use it, but i only can see its benefits if you are going to run the car into the ground and not swap it every 3 to 4 years like most people do, if your not then you paying extra money out to benefit the owner in 10 years time

Again you are right, no proof 2SO works but at the same time it doesn't cause problems. I am one of those people who does keep cars for 10 years plus and I am also risk averse in the extreme so am happy to take action that may save me grief further down the road. Each to their own....  John

like you say each to their own

Interesting topic. I was wondering does it matter what type of 2 stroke is used or is any ok.

If you read the thread in full there is the spec you need to use, any will not suffice

This subject seems to have gone very quiet, not just on this Forum but others as well. I'm still undecided on its benefits if any.

It is indeed interesting that for such a widely discussed subject there has been no conclusive endorsement or repulsion from any industrial party associated with the design and build of diesel engines, motor oil producers or motor industry manufacturers.

So diesel car owners are left with the potential of good or harm if they indulge in adding the correct type and dosage of 2SO to the diesel fuel. And by doing nothing they are assured of nagging "never knowing" if they could have extended the life of many of the components allied to their diesel engines.

So why the lack of endorsement or outright indignant rejection of the claims that have been made across the www on this subject. Tis a mystery as murky as diesel fuel itself.

The one thing that seems pretty clear from this thread is that if you are going anywhere with sub-standard diesel it probably is a good idea to use the stuff. That's what I get between the lines from Y-F's posts and the comments about South African diesel. Whether to use it in the "civilised" world seems much less clear, and as people say, no evidence has been provided. I'm inclined to use it with supermarket diesel, given that they seem to sell the most basic product they can get away with. The FL2 engine, it appears, is not designed to cope with the old-fashioned basic diesel I remember from my youth. I'm increasingly inclined to use premium branded diesel nowadays.

Hi all
I've read this post from the beginning, and must say I am extremely intrigued.
I've just picked up a TD4 GSe, having part exd a TD4 FL1.
The FL1 was starting to have problems with HP pump degradation and breakdown which was causing the injectors to block, so was using injector cleaner regularly to alleviate as I couldn't do without while I took them out and had them rebuilt.
Anyway, as the pump was breaking up, and reading the non lubricating properties of the current diesel fuel we have access to, I'm nearly sold on the idea. I understand how the 2SO would work, as I'm an engineer, but not automotive, but intelligent enough to be able to work out the benefits at this moment.
I suppose what I'm really looking for is not an endorsement per se, but actual forum members who are using this now, and have not suffered as far as they are aware detrimental or destructive effects.
I know this is a big ask, but having seen the threads with all of the Pros and cons, I'm teetering on getting some and giving it a go.
Just need users to answer, not the sitters on the side who still think the earth is flat.
Sorry to be a bit abrupt, no offence meant.

I started adding 2SO from the very day, when I took my brand-new car from a dealer in Dresden, Germany. That was in February 2010. Now, I've got 35 TKm on the clock and I still stick to this rule. When using 2SO I've felt that the engine runs smoother and the car is more responsive at acceleration. I don't want to argue with anybody if this is just my imagination. I just continue pouring into tank a dose of 2SO in ratio described by YF at every re-fueling and that's it..

Thanks Atrix. That's exactly the sort of answer I'm looking for, someone who has done it and able to comment on it. I presume through the winter you haven't seen any problems, as the only thing I'm a little hesitant on is if mixing the 2SO with Diesel will make it more susceptible to emulsifying and causing clogs. However, as it has been mentioned earlier, the 2SO will bond at a molecular level, so this should in some way resist that.
Let's see some more!!!!

I used it in my old car (Fabia vRS) as it used to smoke a bit under load, read that 2SO would probably help, so gave it a try.

After a few tanks, I noticed:
Less smoke at start up
Less smoke under load
Injector noise was reduced, and ran much smoother
Fuel consumption improved by 3-4mpg

Started using it at around 50k miles, used religiously, every tank of fuel, up until it was sold at 85k, and never had any issues with it at all Strathearn Engineering
