He-he "Snake oil" is just a generic term for useless products.
AFAIK it originated in the Wild West when medicine salesmen sold quack
medicine as a cure-all.

No potential damage and it will be OK. I would try a maximum of 1.5
litres at first. Use up threequarters of a tankful of the treated fuel
then top up with diesel only for the second tankful. By the time you
use most of the second tankful you should find a very significant
improvement. If not, try again. If it doesn't work then, the injectors
need calibrating. This is unlikely though not impossible.
As to speed. Nothing works instantly. Think of a washing machine full
of clothes. It takes a couple of hours to wash, then they need to dry
and be aired and ironed before they are clean and fit to be worn
again. Much less palarver is involved with useing an additive like ATF
to clean the injectors. Just apply, use and wait for results. Best to
forget about it for a week afterwards before checking the smoke.
Otherwise it is rather like watching paint dry or yourself growing
old; nothing much happens from minute to minute.

No but I have used it with good results in a Toyota high pressure fuel
system and various other diesel vehicles only on an 'as needed' basis.
Remember to mix well. I fill the tank about a third full and add a
third of the mixture, fill to half full and add half of the remainder
and then add the rest at around the 3/4 mark. No need to be *that*
precise but remember that when fuel is concerned "cleanliness is next
to Godliness"

I sort of knew that, just got the impression that generally snake oil type
products end up causing blockages, like slick50 and the like.

The cambelt was done at 110k (17k ago) at a VW/Audi specialist, and the
timing properly checked on their fancy computer equipment. Is that what you
mean by calibrated (wrt timing) - or calibrated in a different way?

Ah, I get you - so it's got more chance of mixing more evenly throughout the
fuel? Cool.

No, I mean taking the injectors out to spray and pressure test them.
Crack-off pressure falls off over time and also fuel volume injected
gradually increases, usually to the actual benefit of less noise and
more power to a point. That point is where soot emissions become
unacceptable to the extent that either you are concerned or it fails
the MOT soot test.
I don't know whether your engine is a standard unit or a Pumpe-deuse.
Either way, your mileage should not cause this kind of concern. But
you never know. There is a bit of luck involved with running any
engine.
If you are still concerned after doing the cheap additive trick as I
described, then take it to an MOT station and ask them to actually do
a soot test. They will be able to give you a proper measure of the
soot to either confirm your anxiety or take a load off your mind.

No, I mean taking the injectors out to spray and pressure test them.
Crack-off pressure falls off over time and also fuel volume injected
gradually increases, usually to the actual benefit of less noise and
more power to a point. That point is where soot emissions become
unacceptable to the extent that either you are concerned or it fails
the MOT soot test.
I don't know whether your engine is a standard unit or a Pumpe-deuse.
Either way, your mileage should not cause this kind of concern. But
you never know. There is a bit of luck involved with running any
engine.
If you are still concerned after doing the cheap additive trick as I
described, then take it to an MOT station and ask them to actually do
a soot test. They will be able to give you a proper measure of the
soot to either confirm your anxiety or take a load off your mind.

Yeah, I think the fact that it's quite a freely revving diesel engine means
that the power is easily accessible and it's quite easy for it to overfuel a
bit.

It's just a standard one. Proper old-skool design, dating back to 1991!

As far as MOT soot tests goes it's fine - it's only when it's under load
under hard acceleration, or actually during acceleration generally, that it
smokes a bit. I'll give the ATF a try as you've suggested and let you know
how I get on.
Anyway, cheers for all the advice. Good, this internet thing, innit? I'd
happily repay the favour if you ever need any help with talking ***** or
telling mildy amusing stories.

It is a diesel engine and that should not happen at any revs. It is
governed and turbocharged and, in your case, electronically managed.
It should not smoke *significantly* at any revs, though it could give
the occassional puff when suddenly accellerated from low revs.
To gauge what is 'significant', take it for that smoke test.
