Fuel additives: Should you try them?

Should I perhaps use fuel additives to verschandeln the injectors if I'm experiencing gray smoke and poor starting behavior in a warm engine?

Hi,

Okay, I can't give you a precise explanation about the gray smoke that comes from diesel engines yet.
He probably knows that it could be strongly related to the oil.
With gasoline engines, white smoke was always a sign that water had mixed with the engine oil.
Is it the same with diesel engines?
I would definitely take a look at the oil.
Perhaps it's foamy and watery?

You can't really go wrong with diesel additives.
The car is more likely to produce black smoke if the combustion is poor due to dirty fuel injectors.

Michael.

Are there any additives that can verschandeln the injectors? I'm very interested in knowing!

Can anyone provide some information on that?

Thank you very much.

Biodiesel is supposed to have a strong cleaning effect. There have been cases where filters have become clogged after the biodiesel has dissolved the dirt that the diesel had left behind and flushed it into the filter.

It might also help with the nozzles.

Try smartly.

Do you happen to know why that might be the case? I'm really interested.

I've used biodiesel before, but after switching back to regular Super Diesel from Aral, you're just relieved that your car is running properly again. I'm not sure if anything can be added to it for cleaning purposes.

Sure, here is the translation of the text from German to English:

'cu' is a Spanish abbreviation for 'con usted,' which means 'with you.' It is often used in online communication to indicate that the sender is available to chat or talk.

Here is an example of how 'cu' might be used in a conversation:

Person A: 'Hey, I'm bored. Want to chat?'
Person B: 'Cu!'

This means that Person B is available to chat with Person A.

'Cu' can also be used to indicate that the sender is thinking about the recipient. For example, if Person A is thinking about Person B, they might send a message that says, 'Cu.'

In general, 'cu' is a friendly and informal way to communicate with someone online.

Hi,
There are these additives from various manufacturers for all sorts of things.
Sure, here's the translation:

'e.g., from Liqui Moly'

Fuel additives:
Soot stopper.
Fuel injector cleaner.
(im Prinzip reinigen sie das gesamte Kraftstoffsystem incl. Pump.

Oil additives:
Valve cleaner.
Viscostabi.

There's even something to seal minor leaks in the cooling system.
Radiator sealant.

Michael.

ok, thanks.

'If there are additives that claim to verschandeln the pump and injectors, I wonder where all the dirt goes that is supposedly dissolved. You'll likely find minimal deposits from diesel in every pump, without it immediately causing any problems. If these deposits become so significant that you notice them, then they must be quite substantial. When you then add an additive to the tank that is supposed to verschandeln the pump and injectors, it will also work inside the tank. The result can only be a flood of dirt that has to pass through the entire system, if the additive actually delivers on its promise. I don't want to know what happens then.'

My personal opinion on this: Just leave it alone! Many additives are touted as having amazing benefits, but the effects are often not scientifically proven.

Eike.

Can I also verschandeln this manually, or something like that?

Just put it in a bucket with gasoline or alcohol?

Eike's post sounds wonderfully logical - I've never seen it explained that way before!

Hello,

Of course, this will also dissolve any accumulated dirt from the tank and the pipes.
The diesel particulate filter installed in the engine compartment captures all of these particles (approximately 0.004-0.010 mm in size).
It's hard to imagine him not doing that.

Even after filtering, slight deposits are dissolved from the pump, pipes, and injector nozzle, but these deposits are all within the micrometer range.
Similar additives are added at all gas stations.
It's better for some, worse for others.
It would be new to me if adding something could cause damage.

I would be more concerned about whether the gas station had been recently restocked with fuel.
During the process of filling the gas station tanks, all sorts of things can get stirred up.
But as I mentioned, that's what filters are for!

@Chris (Mtw13ve)
What exactly do you want to clean?
The fuel injectors have such small openings that they should never be touched with your fingers to avoid clogging.
One thing that could be done is to have the nozzles cleaned out at a workshop.
This also allows you to determine whether the nozzle produces a fine mist or rather distributes small droplets, which would then cause poorer combustion.

Hi, I just wanted to go through everything and see what needs to be either replaced or cleaned. What about the electric fuel pump? I guess the injectors probably need to be replaced after 240,000 km anyway... What do you think makes more sense?

After experiencing starting problems during the winter, I added a can of Liqui Moly diesel injector cleaner to the fuel tank and then drove it for about half a tank. Since then, the engine has started a little better when cold (I think the glow plugs might not be in the best condition).
