How to clean dirty diesel injectors : a guide that will explain how to do it yourself cleaning of diesel engine injectors .
The injectors of a diesel engine are a key component of the car’s powertrain assembly. Over time, combustion residues – especially in the case of dirty diesel fuel – tend to accumulate and encrust the injectors.
Dirty diesel injectors, symptoms
The cleaning of the diesel injectors should be done periodically, before the onset of symptoms. The symptoms of dirty diesel injectors , when they arise, testify to an already overt problem.
Early symptoms see a strenuous cold engine start, excessive fuel consumption, increased noise and loss of power.
With clean injectors, combustion will be more efficient and vehicle performance should improve from the first acceleration by reducing both noise and exhaust fumes.
How to clean diesel injectors
There are liquid diesel injector cleaners on the market. These are additives that must be added to the classic diesel. These additives, entering the circulation, eliminate the traces of dirt which, over time, have accumulated in the injectors and in all the mechanical components involved in the combustion of the fuel.
It is important to clarify that these additives are excellent and effective only if they are to be used periodically and not when the problem is extremely obvious or if you made a mistake in refueling by adding petrol instead of diesel.
Cleaning diesel injectors: wrong refueling, petrol instead of diesel
If you have dirty diesel injectors because you have put petrol instead of diesel, you will be forced to go to a mechanical workshop that will disassemble the fuel system and mechanically clean the injectors.
The cost of cleaning the diesel injectors , emptying the tank and lubricating the injectors, may vary according to the mechanical workshop you are contacting.
Last month, I took my new 3008 to the Peugeot dealership, I had lent it to my mother who, taken from old habits, had refueled the wrong way by filling up with petrol instead of diesel!
For cleaning the injectors and the entire fuel system, I had to incur a cost of 250 euros. On this occasion, I asked the mechanic about the validity of the additives for cleaning diesel injectors , the opinion was quite positive, indeed, they were advised to me as long as I use them periodically.
The mechanic advised me to use a good diesel cleaner due to the poor quality of the diesel fuel circulating in the filling stations.
The cost of simply cleaning the injectors (without emptying and cleaning the tank) would have been around 150 euros.
Why do diesel injectors get dirty? According to the Peugeot mechanic, they get dirty due to the presence of water in the diesel and poor quality diesel, rich in incombustible residues that accumulate in the injectors .
How to clean diesel injectors without disassembling them
The cleaners mentioned above allow a thorough cleaning of the diesel injectors without resorting to mechanical interventions. It is a very simple DIY and affordable for everyone.
All you have to do is “intercept” the best product for cleaning diesel injectors . Make sure – of course – to choose a product for diesel engines!
If you are looking for the best product for cleaning diesel injectors, know that, most of the products on the market, are quite valid because they have similar formulations.
How to use the additive to clean diesel injectors?
It will be necessary to bring the car almost dry (in reserve). Fill up with quality diesel and add the additive to the fuel tank.
The additive for diesel injectors will clean them better and lubricate them so as to protect them and keep them clean longer.
Also this time you will have to run out of fuel and refill with a quality fuel such as Blue Diesel (as recommended by the mechanic). From the next refueling, then, if your wallet needs it, you can go back to the cheaper diesel.
Among the best additives for diesel injectors on the market, I was recommended Bardahl TOP Diesel which can be bought on Amazon at a price of 19.65 euros with free shipping. This additive restores the efficiency of the car’s fuel system, manages to clean and descale the injectors from the first treatment.
