Adding 2 stroke oil to fuel - Interesting reading!!

That's the point, you need a crystal ball to foretell the future combined with a spreadsheet of know and unknown variable factors.
As much as I love my Yeti it's just another example of 'white goods' particularly with China FTA.

If you read through the experiences that others have had i'm sure you would be reassured that it's a positive result for the DPF.
That's from actual experience, not just theory.

I'm not specifying any one item.
All the potential financial disasters involve DSG, Haldex, injectors, turbo, split ac etc etc
For those not equipped to cope, in a DIY sense, with this complexity need to remember that after 5 years any one of these could make your much loved vehicle a financial black hole in quick time.
New cars are sooo desirable at runout time your own car is living on borrowed time.
"Careful analysis" can be painful.
Believe me, I wish it wasn't so and I could continue to do all my own basic maintenance and KNOW it wouldn't burn me financially but emissions and economy targets are killing the new car as a long term prospect and car salesmen love it!

Ahh this old discussion. Last time this was at the top of the heap I was running b100 in all my diesels so it was a moot point for me. Right now, however, I have no B100 to buy near me so I have been on dino diesel for a while.

I took the audi for a fill up tonight and literally as I was walking out of my garage noticed an old bottle of 2SO in the garage, so I emptied it into the tank before I left - about 120ml.

By the time I'd gone to get fuel and then driven back home again round trip of about 4km, the darned thing was purring even more smoothly than usual.

I did try this in one of my old golfs a few years back when I lived in newcastle and didnt have access to bio then either, and remember something similar happening.

I wont advocate its use to anyone who isnt convinced themselves from all the things they can read, but I'll certainly give it a good go for the next few weeks and see what effect it has on economy, if any. Personally, I have nothing to lose.

I will also be interesting to see of the Audi starts blowing smoke for a day or so

Just so long as it doesn't start to sound like a Trabant

Just read your fuelly and 6.7L/100km for the 1.6TD Caddy. You must have heavy traffic in your neck of the woods when it's rated at 5.7L/100km. I got the rated 6.7L/100km for my 2.0TD and 2SO oil lowered that to 6.3L/100km by calculation at the pump.
So you could expect the same saving from yours, after all the carbon gets cleaned out and also have it quieter, cleaner and smoother.
The only thing is, it doesn't say 'Diesel fuel additive' on the container but none of those branded diesel fuel additives have ever made any difference when I have tried them.

Why would this happen?

Why would this happen?

Because it should clear out the deposits. Several people have reported that older engines smoked a bit on the over-run but it cleared after a few days and they could feel the improvement.

I've a rule in my business - "use always as per instructions" I think it's valid in almost everything in people's life.

I can see where you're coming from now and can understand your point of view.

I was trained in both aircraft and automotive, engines mainly and spent a fair bit of time diagnosing and solving problems. I always enjoyed the problem solving and creative engineering. Prior to that I hated being told to do something 'because I said so' would throw instructions in the bin to do it the hard way and still do. Sometimes I have to fish them out when i'm stumped!

So you accept the instructions as gospel while I always look for a better way and often find them. Our brains are wired differently.

That doesn't make any sense really. The mass of deposited carbon in the combustion chamber is very small. If it all got cleaned out at once, which it certainly won't, it would amount to nothing more than a quick puff of muck.
I've rebuilt enough diesel engines to know what carbon buildup looks like and how and where it builds up.
The only possible reason I could conceive of for temporary smokyness brought on by some kind of fuel related cleaning, would be that between carbon buildup being baked on and flaking off, it might foul the spray pattern of the injectors... But even that seems to be a stretch.
As it happens, my Audi only ever really smokes on startup and I note that today it didn't seem to really.
