Does this stuff work?or do the injectors need to be removed and cleaned /reset?

What stuff?
I have used fuel additives and feel I can tell a subtle benefit in reduced tendency to produce smoke and smoother running engines even when used extensively at slow speed.
But I would imagine fuel additives may not cure an injector fault

I would also assume that given the average car tank is 60 or so litres and the average boat somewhere between 700 and 4000 litres you are probably best to use it on as close to an empty tank as possible or you will spend more on the cleaner than removing the injectors!
However one article at random says they dont work!
http://www.superstreetonline.com/how-to/engine/impp-1106-fuel-system-cleaners/
This seemed relatively scientific - but the car forums all have different views so I suspect you will get nothing different on here!
The pictures people post on here of injectors show frequent carbon deposits on the nozels. I can see that the inside of the injector MIGHT be cleaned, but not the outside of the nozel which is basically where the explosion happens and the cleaner will simply be ignited.
Even the inside - given the massive portion of diesel in the fuel compared to cleaner I would be sceptical that it could honestly have much impact. If there were a way of getting pure cleaning fluid to the injector without combustion it would become more plausible.
Just my view!

Thanks. My thoughts also.

I had trouble with a corsa diesel with irregular engine running,put some injector cleaner in the fuel filter and the rest in the tank,made an immediate difference and been ok since.

i can see if you put it in the fuel filter ( as long at this ok and does not cause other issues ) then neat cleaner could well do some good.

im not entirely sure what people are trying to acheive with injector cleaning fluids.
i understand completely and have benefited from diesel purge for cleaning the wetted surfaces of the fuel system.
its not a big undertaking to remove the injectors, clean the nozzles with a brass wire brush and pop test them while they are out.
build up of carbon can then be reduced by cetane improvers which are much more concentrated and finacially worthwhile making the engine burn the diesel more efficiently, or giving a bigger bang for your buck.

MAN manual specifically says don,t use these products ( Bosch’s injectors )
Aside there’s the dilution issue as they seen to sell car sized doses .
I think there’s stuff allready added in diesel anyhow ?
Then ( allow me stand in my pulpit
and preach) what’s the point if you are NOT gonna generally zoom about at the correct EGT anyhow ?
Your agglomerated soot particles from excessive low speed low EGT,s will stick and eventually knacker the tips anyhow .You know 8ugger up the very spray pattern that you think you are trying to protect with the injector cleaner .
Lack of use combined with inappropriate use shortens the life of marine diesels assuming you follow the maintenance regime.
Having said ^^^
Water in the fuel is the real injector killer .WIF
Pretty catastrophic with Common Rail - CR
So ensure the filtration side is as good as it can be before you seek out any snake oil .
Consider fitting if you have not got any a bowl primary filter so you can see it and drain it .
Some WIF,s .
Check filler cap seals / vent pipes etc .
Occasionally drain off the crude if any with the tank drain cock if you have one ?
Or if you are itching to buy a little bottle - to cure your insomnia
buy something like a water dispersant - anti bug additive.
There’s products like Startron diesel additive allegedly dissolve any water into the fuel thus eliminating the fuel/ water bug breading interface .Imho ideal for over wintering where the turn over in the tank is basically zero for the coldest months .
With perhaps occasional use in the summer with weekly fill ups and high turnover in a content hot / warm ER - Like in the Med season .

Remove water from the fuel, dissolving it sounds all wrong.

There are two types of fuel treatment
The type that causes any water to drop out
The type that disperses the water microscopically in the fuel.
Which is best is a matter of opinion – but both are available .
Neither is a cure for significant water in fuel issue. We are talking about microscopic amounts of water

Yup it’s part of overall WIF hygiene .
Just it’s the H2O that you need to worry about -re injector longevity.

I put 2 or 3 bottles of STP petrol fuel injector cleaner in the tank of a 2.8 V6 Granada I bought cheap. The result was dramatic. Initially it was only running on three or four cylinders, and wouldn't do more than about 40 or 50 mph. After treatment it was good for 120 
It gradually picked up; first running consistently on 4, then 5, then 6, reliably, with a good smooth tickover.

Prior to MOTs I dose my elderly Disco 1 with injector cleaner on an almost empty tank before taking it for a blat. Clouds of soot ensue.
