Shopping guide


The first aspect that you must bear in mind before buying your injectors cleaner is the type, which in turn will be determined by the combustion mechanism with which each vehicle works, that is why you will find a special one for those who come to gasoline and another for diesel; Each one is different and brings specific additives for cleaning.

In this sense, you must bear in mind that the compression of a diesel engine is much greater than that of gasoline, so we should not use the same products for both. We can tell you that the variety that you will find in the market is really high, so you can get some diesel injectors cleaner that fits the needs of your car.

On the other hand, it is important to know that experts recommend cleaning injectors every 4,000 to 10,000 kilometers because in this period the accumulation of waste can be greater. Everything depends on the behavior of each vehicle and the use we give it.

You should also take into account that the cleaning of injectors can be done by other mechanisms, such as the ultrasound processor with a sweeping kit, but both are much more expensive and that is why we recommend the use of additives to economize and obtain very good results.


Just as cars are different, not all cleaners offer the same characteristics. If you have noticed the increase in diesel consumption, the loss of force when starting and the exit of gases or black smoke when you are driving, then it is time to clean the injectors.

Diesel nozzle cleaners provide a number of benefits to your car. In the first place, they allow saving on fuel consumption, since they reduce the expense we make each week. Even if we do not see it right away, in the long run, we can save a good amount of money.

Some cleaners are also responsible for passing their additives throughout the area of fuel injection and its pipes, managing to eliminate almost any type of dirt that may be found in them, avoiding corrosion and the release of toxic gases for humans. Also, after cleaning with the use of additives, the vehicle can regain strength, because when the injectors are dirty or have particles of fuel, the car does not work with the same power.

Finally, if you are doing a comparison of diesel injection cleaners, it is important to take into account factors such as the place where you are, the service station where you load fuel and even air pollution, as these can affect the frequency of cleaning that will be given to the injectors.


Each brand and model will offer you its own presentation, which will be determined by the number of milliliters in additives it can bring. You will find bottles of la iter, 500 ml or small 250 or 300 ml.

According to experts, it takes about 400 ml to clean up to 70 liters of diesel, but it will depend on the type of additive, for this reason, it is very important to pay attention to the specifications of each product.

Also, it is important that when you go to apply the cleaner for diesel injectors, the tank of the car is completely full, so that it performs the function effectively. In this sense, you must drive the vehicle as usual and replace the fuel when it is in the reserve or is almost empty.

On the other hand, it may be that the amount of content that each model brings increases the price of the product. If you’re wondering how much it costs, you can rest easy because your budget will not matter, since you can find from a very economical to the most expensive one.
