I did an injector leak test when I started this trial and will do another one in a couple of months to see what the diffference is. the problem is to find a high concentration injector cleaner on the market. If you are interested I can send you one to try (I got this from an american company to try so more tests would be excellent).

can you please tell people what this magic cleaner is that you are using? you keep referring to it yet never tell anyone what it is

just tell us all the name and we will source it ourselves

It may be worth knowing that Volvo forbid any oil or fuel additives and any warranty claim involving engine or oil or fuel system will be rejected if they find traces of additives ..
This is for warranty of course , but i'm sure they have a very good reason for this ...

yes they do, its another way to get out of handing out money for dodgey parts (injectors) lol

Can we please have an update on your tests, as well as where this 100% concentrate can be obtained from.

Also, have any testers reported that the concentrate has damaged their cars?

It's probably Diesel Purge he's talking about and it's excellent but I've not heard of it turning a badly leaking injector into a fully functioning one.

About half of all bad injectors are just suffering from gum deposits and can be restored using a direct feed injection system cleaner. There are very few companies that I trust in terms of both producing a product that both works and does not produce long term side effects. Liqui Moly are definitely one of those companies and they make very good engine oil and fuel additives designed for dealing with specific issues. Lubriguard and B&G are also good additive companies.

I use diesel purge every time I change fuel filters, as it's easy to just top up the fuel filter housing with it (Not as efficient as using a loop to can method). I don't bother to use any other type of fuel additive as the diesel sold in Germany has enough Bio content to provide good lubricity (Effects the life of the high pressure fuel pump) and keep the fuel system clean.

Even with good quality diesel you can still get very long term gum deposits if you do a lot of short tripping, although if your car does not have to suffer such abuse there is probably no reason to use a fuel additive at all. Some additives that are added to a fuel tank will prevent gum deposits, BUT they are a lot less effective at removing them than a direct feed cleaner.
Poor quality fuel filters can easily damage a fuel injector and no fuel additive can fix that type of damage.
