How to choose your injector cleaner

With a plethora of injector cleaners on the market, it can be difficult to choose the right product for your car. For a successful purchase, here are the criteria to remember:

#1 - The type of car

All cars are different and require different maintenance. If your car has a diesel injection system, you'll need a diesel injector cleaner. Of course, if your car has a gasoline engine, you'll need a gasoline injector cleaner. If you are in any doubt about this, don't hesitate to ask a mechanic for advice.

#2 - The type of cleaner

The choice of injector cleaner will depend on the condition of your car. If your car shows no signs of a malfunctioning injection system, you will need a preventive product. On the other hand, if the car's behavior indicates that the injector is clogged, you should use a curative product. Remember that the different categories of injector cleaners are not used in the same way.

#3 - The composition of the product

Injector cleaner is a product that contains specific additives capable of treating clogged injection systems in depth. So, before buying a product, always refer to the information on the bottle. Even if the main components are not detailed, you will get to know the additives that are used to dislodge the scale from the injection system components.

#4 - The size of the car

The size of the car will give you an idea of how much injector cleaner you need. Indeed, the amount of product needed is not the same depending on whether you drive a city car or a large SUV. Remember that the fuel consumption of a car has a direct impact on the amount of injector cleaner you need to perfect the cleaning of the injectors.

#5 - The reputation of the manufacturer

Letting yourself be seduced by products with very attractive prices is a mistake not to be made. Injector cleaners offered at bargain prices often have limitations, or even defects that can become detrimental to the car. In order to prevent this from happening, take a closer look at the reputation of the manufacturer.

How to use an injector cleaner ?

When a car is stopped and the engine is still warm, the chemical components of the fuel evaporate and settle in the injection system. When the injector becomes clogged, it can no longer perform its function properly, resulting in a loss of power, increased fuel consumption and starting problems.

To solve these problems without driving the car to the garage, the use of an injector cleaner is necessary. This product can be used in 2 different ways:

Preventive use

It is a question of preventing the appearance of the dysfunctions of the injector. In this case, the injector cleaner should be poured into the fuel tank every 5,000 km, for example. Be careful, because while some products require a full tank, others only require a volume of fuel of about 20 liters.

Curative use

The product is used when mechanical problems have already appeared. In this case, it is necessary to opt for a more concentrated injector cleaner in large quantities. To do this, pour the product in small quantities into the fuel filter or directly into the injection pump. It is also possible to pour the entire contents of the bottle into an empty tank before adding fuel. This requires that you run at full throttle until the cleaner can take effect.

How do I know if an injector is clogged?

Your car's injector needs cleaning when it has trouble starting or when it starts late. If you feel the throttle is slow to respond, it means that fuel injection into the combustion chamber is inadequate. But the most common signs in all cars are an unusual increase in fuel consumption, the production of a black combustion gas and a loud noise from the engine. Don't wait for any of these symptoms to appear before servicing your car's fuel injection system.

The different types of injector cleaners

Our research has enabled us to highlight 2 categories of injector cleaners, namely diesel injector cleaner and gasoline injector cleaner.

Diesel injector cleaner

Diesel Injector Cleaner cleans all components of a diesel engine injection system. Among other things, it cleans the injector, valves, combustion chamber, pumps and pipes. When used properly, this product should remove black fumes, reduce high fuel consumption, and ease the car's cold start process.

Gasoline injector cleaner

This product works in much the same way as its diesel engine counterpart. Of course, this type of injector cleaner can only be used in a car that uses gasoline as fuel. After treatment, engine wear, noise and fuel consumption will be reduced. In addition, the injectors and pumps will no longer seize up.

Injector cleaner or engine descaling additives ?

Injector cleaner

As it is very rich in active ingredients, the injector cleaner (whether gasoline or diesel) will completely clean the car's fuel system, notably thanks to propanol and open-chain hydrocarbons. The injector cleaner will also sanitize the engine's combustion chambers, which will improve the quality of ignition and reduce fuel consumption. Finally, this product will remove water residues from the fuel by means of alkanes.

Engine descaling additives

Similar to injector cleaner, descaling additives are sold at service stations and auto centers. These cleaning products are used to get rid of some of the carbon build-up on the fuel injection system and multiple engine components. To use this product, nothing could be simpler. Pour the contents of the bottle into the fuel tank and drive a long distance for the product to take effect.


In reality, these 2 products are complementary. The use of descaling additives does not exclude the use of an injector cleaner. However, the action of the latter is more targeted. By preventing the clogging of the injectors, the product extends their life. With this product, you will not have to change this essential part of the car prematurely.

5 good reasons to use an injector cleaner

Injector cleaner is a product that must be added to the fuel in order to infiltrate the car's injectors. You will see that this additive will offer many benefits to your car.

The fluidization of the combustion

The injector cleaner will clean the circuits of the combustion chamber of your car. This will allow your car to consume less fuel while using it in the best possible way. Imagine the savings you will make by investing in a single bottle of injector cleaner. In addition, better fuel combustion will also reduce the amount of fumes released by the car.

Corrosion prevention

A good injector cleaner will help prevent premature corrosion of the injection system. The active ingredients in the product will remove carbon deposits and the slightest traces of water in the system that cause oxidation and crumbling of metal parts. The injector cleaner is the best way to prevent the seizing of engine components.

Passing a technical inspection

The injector cleaner will allow you to prepare your car for a technical inspection. As mentioned throughout this buying guide, this product is very effective against the clogging of the injection system that is responsible for the car's malfunction. Remember, a well-maintained car will never fail a technical inspection.

Guaranteed compensation

The use of an injector cleaner will avoid problems with your insurance. If an accident occurs, you will not be compensated by your insurance company if its investigations prove that your car was not in good working order at the time of the accident.

The ecological gesture

A well-maintained car will not emit a huge amount of polluting gases when it is running. Beyond the technical aspect, the use of an injector cleaner is therefore a responsible gesture from all motorists.

The best brands of injector cleaners

In our opinion, the best brands of injector cleaners in 2022 are :


Bardhal has been marketing a wide range of car care products since 1936. Today, the injector cleaner is its most popular product that motorists around the world are snatching up.

Created in 1918, Facom is a French brand specialized in the production of tools (automotive, aeronautical...). Today, the brand is dedicated to the production of maintenance products, including injector cleaners for both gasoline and diesel engines.

Mecatech is a young manufacturer. Indeed, its activities as a producer of lubricants and fuel additives only started in 2006. Approved by major oil groups, Mecatech's injector cleaners are among the most appreciated on the market.

Wynn's is a manufacturer immensely known for the quality of its lubricants and additives for cars. By using a Wynn's injector cleaner, you will prevent contamination of essential fluids and solve any problems your car may be experiencing in record time.

In business since 1986, DieselSprint specializes in industrial lubrication and additives for the automotive sector, especially diesel engines.

Ask about the product

It may seem trivial, but before you buy an injector cleaner, always find out what type of engine the product is for. Is it a gasoline or diesel engine injector cleaner? Using the wrong product can damage your car, so keep that in mind.

Prefer big brand products

Choose an injector cleaner that is offered by a well-known brand. This will allow you to get help in case a problem comes up after using the product. Customer support is always appreciated especially if you are not very mechanically savvy.

Use injector cleaners that have warranties

Injector cleaner is not a perishable product, especially if it is not a one-time use. If you plan to buy some, especially to perform a preventive treatment, make sure the additive does not expire after 6 months. This way, you can use it with peace of mind by following the instructions.

Ask a mechanic for advice

Certainly, it is easy to use an injector cleaner, but if you have even the slightest doubt, it would be best to entrust the treatment to a professional. Ask your car mechanic for advice, or let him or her perform the operation, while observing it meticulously. That way, you'll be able to do it next time.

Check your car's mileage

As mentioned earlier in this buying guide, the use of an injector cleaner as a preventive treatment should be repeated every 5000 km. To avoid starting a curative treatment, check the mileage and repeat the operation when the time comes.


How to use an injector cleaner ?

Whether it is intended for a gasoline or diesel engine, an injector cleaner can be used as a curative or preventive treatment. In preventive mode, the product must be added gradually to the fuel every 5,000 km. In the curative mode, the contents of the bottle must be poured into the tank.

When to use an injector cleaner ?

There are no good times to use an injector cleaner. Don't wait until your car is malfunctioning before adding these additives to your tank. Mechanical professionals recommend a preventive treatment every 5,000 miles and a complete injector system cleaning every 10,000 miles.

How to recognize a car that needs an injector cleaner ?

It's easy to recognize a car with a clogged injection system. The most common symptoms are increased fuel consumption, loss of power, unusual production of black smoke and disturbing engine noise. Sometimes the car simply refuses to start.

What is the difference between a gasoline injector cleaner and a diesel injector cleaner?

These 2 products differ in their use. Indeed, a gasoline injector cleaner is used for a car whose engine runs on gasoline. The diesel injector cleaner is therefore reserved for a diesel engine. The two products must not be confused, as this could harm the engine's proper functioning.
