Ask a Question
If we are talking about professional cleaning, then it takes place on professional equipment with special tools. Look for this service in your service station. For the rest, various additives from this rating will help.
Question to the expert
What if there are no additives available?
For those who cannot find an injector cleaner on sale, but plan to flush it, we can recommend carburetor cleaning fluid. The products have identical compositions.
Additives against professional cleaning
The first method, which involves pouring additives into the tank, is amateur and intended for independent use. The rest of the methods are already professional.
If we rely on reviews, the results of real tests and research, the effectiveness of professional cleaning on a ramp and under the influence of ultrasound is objectively higher. But they are aimed at combating the most serious deposits caused by prolonged or improper operation of a car engine. This does not mean that additives should not be used. They serve as a preventive measure that is aimed at removing minor contaminants and keeping fuel nozzles clean.
You shouldn't place high hopes on cleaners. They may not justify them. When the sprayers are heavily contaminated and cannot do their job efficiently, you cannot expect a miracle from the additive. If the manufacturer promises to clean everything to perfect shine and cope with the most difficult types of dirt, he is blatantly lying.
Causes and signs of poor performance of diesel and injector injectors
Car owners consider cleaning the fuel system of diesel or gasoline engines a basic operation that ensures the normal functioning of the power unit.
Important! The injectors act as a unit that allows fuel to pass through for further mixing with air. In theory, the fuel arrives without foreign impurities, but in practice, foreign compounds often clog the injectors. This causes engine malfunctions.
Up to 90% of car owners encounter low-quality fuel, so they are familiar with deposits on the injector needle valve. The denser this layer, the higher the likelihood of malfunctions in the fuel system.
This is evidenced by a whole group of signs:
- with each attempt to add gas the vehicle twitches;
- fuel costs increase significantly;
- at idle the engine is unstable;
- difficulty starting the engine;
- when unscrewing, it is clear that the spark plugs are dirty, despite the recent change;
- speed drops for no apparent reason;
- the sensors alternately fail, producing various errors that actually do not exist.
To prevent engine failure, prevention is important. Experts recommend producing it based on mileage. The maximum permissible limit is 40,000 kilometers.
Important! Following simple rules will help reduce the risk of injector contamination: buy only high-quality fuel, spark plugs and oil. And don't skip scheduled maintenance.
Types of fuel injector cleaners
Injector cleaners for gasoline engines and diesel engines, with all their diversity, are divided into only 2 categories, each of which has its own characteristics.
Solvents
This option is the most common and effective. The operating principle of solvents is simple:
- neutralization of carbon deposits;
- breaking them down into small fractions.
Small particles escape freely through the exhaust system, leaving system components clean.
The composition of such products includes polyetheramine. It is the basic active ingredient, to which the manufacturer adds a number of additives and auxiliary components.
Detergents
Detergent compositions are less popular. Craftsmen and car owners often argue about their effectiveness and cannot come to a common opinion. Most people are sure that washing liquids do not completely clean the system - they only remove part of the carbon deposits, creating a dangerous illusion of cleanliness. This is especially true for heavily soiled elements that have not been cleaned for a long time.
Important! Experts recommend detergents to owners of new cars. They do not require complex aggressive cleaning, and prevention using light compounds will protect parts from the formation of deposits.
Soaking in dimexide
Dimexide has the property of cleaning objects from hydrocarbons and oils, and the drug is purchased at the pharmacy. The implementation of this option is quite simple: you need to remove the ramp with the injectors, then disassemble it into parts.
Dimexide is poured into a wide-necked canister or other container. Now you need to lower all the ramp parts into the canister and leave them there for ten or twenty minutes.
The process is completed by wiping the elements with dry towels and installing the spare parts in place.
The best manufacturing brands
Should I clean the injector with a detergent, additive or solvent? This question is asked by almost every car owner. And sooner or later he realizes the need for cleaning. But in order not to worry about your car, you should choose products only from trusted manufacturers.
Chevron
The company arose in the late 70s of the 19th century. From the first days it was engaged in the production of petroleum products and chemical compositions for various purposes. Today it occupies a leading position in the industry. Among its range of products, injector flushing into the tank is in great demand. It is presented in a wide range.
Red Line
The company was founded at the end of the last century in California. Its goal is to produce lubricants for the racing segment. Until now, it produces the best products for motorsports, while simultaneously producing formulations for ordinary car enthusiasts.
Royal Purple
One of the oldest companies in the segment. Its specialists have been working on lubricant formulas for more than two centuries. Each new sample is more effective. That's why new items from Royal Purple are instantly sold out.
STP Oil
The company began producing lubricants in the middle of the last century. They gained their fame thanks to Nascar. And they are still considered one of the best.
The most popular additives for cleaning the injector are those added to the fuel tank.
How to clean injectors yourself
Today we will offer four ways to clean the fuel system of a gasoline engine.
They look like this:
- Using carburetor cleaner.
- Application of a flushing cylinder.
- Adding acetone to gasoline through the fuel tank.
- Using Dimexide in the process.
Each of the listed methods has features and rules that should be followed when using the options. Because of this, all paths are considered separately, with consideration of the procedure.

What to look for when choosing a cleaner
Nowadays they produce a lot of chemicals for cleaning fuel systems, and choosing the right one among them is not easy. It is necessary to familiarize yourself with the characteristics of all products, avoiding too aggressive ones that can damage system parts. Many car enthusiasts use a gasoline additive because it saves them from unnecessary costs: effort, time and, of course, financial ones. When choosing it, you need to consider:
- The same aggressiveness of the product, so as not to damage the rubber and parts of the polymer system.
- The viscosity and octane number of the fuel and the cleaner must match.
- The force of impact on deposits. It is desirable that the additive dissolves contaminants and does not turn them into flakes, which can lead to failure of spark plugs and various sensors.
Advice!
It is worth assessing the degree of contamination of the injector nozzles and other parts. If it is small, then the mentioned additives and other non-aggressive substances that clean the fuel system using special installations will be quite sufficient.
If the engine is running at the limit due to an excess of accumulated deposits, only the intervention of professionals will help.
The best analogues of injector cleaners
The injectors become dirty in any case during vehicle operation. The driver can drive carefully and refuel with the highest quality fuel, but sooner or later he will be faced with the need to clean them.
And the main reason lies in the composition of the fuel itself. It contains a lot of foreign impurities:
- additives;
- sulfur compounds;
- water;
- benzene;
- fine dirt particles.
During engine operation, the fuel heats up and all excess components turn into a sediment, which is a viscous resin or varnish. Such deposits interfere with the normal operation of the injectors and the system as a whole. Without cleaning, problems that arise cannot be dealt with.

Why do you need to flush the injectors?
Contamination of the injectors means a decrease in the dosage of the combustible mixture, soot deposits and, as a result, a complete cessation of the fuel supply. The tightness of the injector valve seal is broken, fuel leaks occur, and the toxicity of the exhaust gases increases.
Signs of dirty injectors:
- difficulty starting the engine;
- reduction in engine power and increase in vehicle acceleration time;
- increased fuel consumption;
- an increase in detonation in the engine cylinders, the appearance of interruptions in the exhaust system;
- instability of engine idle mode;
- breakdown of sensors that regulate the air supply to the fuel system.
For cooling system
Vehicle owners rarely consider flushing the cooling system a priority. But its clogging is fraught with a long list of problems:
- pump breakdown;
- radiator failure;
- periodic engine overheating;
- improper operation of the stove.
And this is just a sample list! In each specific case, it is worth contacting the experts. They will determine the level of contamination in the system and suggest the best cleaning method.
Important! Professionals recommend cleaning the system every time you replace antifreeze. The maximum possible period of operation of a vehicle without cleaning is 3 years.

Mechanical cleaning
This method was relevant until the mid-90s, when car engines were not so capricious. Its essence is to flush the removed injector using the car battery. To do this, you will need to unscrew all the injectors and assess the degree of contamination.
Then you need to take the battery, two wires with terminals and a cleaning agent in a bottle. At the beginning of the process, connect one end of the wire to the battery, and plug the other end into the injector connector. Another wire needs to be hooked onto the outlet part of the nozzle, and the free end should be left dangling.
Now you need to connect the bottle with cleaning fluid to the inlet. Next, you need to start spraying while simultaneously shorting the free end of the wire. Inside the nozzle, the solenoid valve will operate (to open), and the liquid will pass through the part.
For engine
Gasoline and diesel power units become dirty at different rates. Therefore, to clean them, experts recommend using specialized compounds designed specifically for a particular type of engine.
Important! Diesel engines are the most sensitive. They should be cleaned not as they become dirty, but at regular intervals.

Pros and cons of cleaning yourself
The first argument in favor is savings. Some car enthusiasts save money and do not go to the service station. Clean the injectors yourself. This is an acceptable option when it comes to older engines, where the intake system does not depend much on the central control unit of the car. In addition, it is important to consider the mechanic’s experience. If a person disassembles and maintains an engine for the first time, there is a high probability that he will not cope with the task.
The second advantage is the objectivity of the assessment. You will certainly know the exact status of your fuel system. No mechanic at a service station or mechanic at a dealership can deceive you. Self-cleaning will show the true picture of what is happening. However, you will need to master minimal skills in car repair.
The main disadvantage is the impossibility of washing to an “ideal” state. No cleaning method at home will give you the same quality as professional equipment in a specialized service station.

For transmission
An automatic transmission is a complex system of components and elements through which fluid constantly circulates. Its contamination and increase in viscosity leads to serious consequences:
- increased wear;
- resource reduction;
- accumulation of wear products in key components;
- reducing pressure in the system and more.
Traditional transmission fluid changes will only provide short-term results as sediment will remain in the system. Therefore, before replacing, it is imperative to clean the transmission. Cleaning liquids can also be used for preventive purposes.

Wynns
One of the most famous flushing agents for cleaning injection systems. According to the majority of car owners, Vince has proven itself to be a liquid that can effectively clean not only injectors, but also valves and combustion chambers. The product easily copes with even stubborn carbon deposits. It easily cleans mineral deposits.
Some experts compare this product in terms of effectiveness with the ultrasonic cleaning procedure. The main thing is to use the liquid in recommended dosages. Otherwise, you may do more damage to the fuel system than clean it.
Methods for cleaning and flushing the injector
Cleaning is traditionally done in one of three ways. Some car owners use all options depending on the situation. Others use only one familiar method.
Gasoline additives for injector flushing
Adding liqui moly additive to gasoline
This method is considered the least energy-consuming. Moreover, it is also the cheapest of all. Additives are sold in car dealerships in a wide range and, if necessary, are simply poured into the tank.
Masters recommend doing this regularly as a preventive measure. If signs of contamination have already appeared, it is worth adding a double or triple dosage of the product.
Important! If the gas tank is heavily contaminated, additives should not be used. All the dirt can go into the electric fuel pump, which will cause it to fail. And replacing this element is very expensive.
Washing and cleaning the injector with ultrasound
Cleaning injectors with ultrasound
This is one of the most popular and effective cleaning methods. It is based on the complex effect of ultrasound and solvent on previously removed injectors. Vibration does not harm the elements themselves, but causes carbon deposits and contaminants to separate from the metal.
Important! In general, the method is convenient and only takes about an hour. But its cost does not always satisfy car owners. It is due to the use of high-tech equipment and a significant amount of work on removing and installing injectors.
Flushing the injector without removing the injectors from the engine
A highly effective method based on connecting the engine to a special installation that drives a cleaning composition through the system. After working in this mode for half an hour, even old deposits are washed away.
Methods for cleaning injectors
The injector is cleaned using various means. The most popular option is automotive chemicals.
Washing methods:
- Additives for injectors: they are poured to clean the injector into the tank. You can buy injector cleaning fluid at a car store. The capacity is enough for 40-60 liters of gasoline; filling is done exclusively into filled tank.
Application scheme: additives are mixed with the fuel mass, then pass through the elements of the system, simultaneously removing deposits and soot areas. Additives don’t have any particular disadvantages, but if the filter is clogged, they will be powerless for fine cleaning.
- Injector cleaner: devices that work with or without dismantling the injector elements. If dismantling of elements is necessary, the connection is made using a ramp. When performing work without shutting down, circulating liquid is poured into the system. The price is affordable, the results, when using high-quality equipment, are excellent.
- Ultrasound is an effective, albeit expensive option; it is used to restore the functionality of the injection unit. No cleaning compounds are needed at all. Ultrasound is effective for heavy deposits when other removal methods are powerless.
Prevention can be carried out using any of the methods described above. The optimal frequency of procedures is every 20-25 thousand kilometers, regardless of the current state of the fuel supply unit.
It is especially important to carry out preventive maintenance for cars with a distributor injection system.

If the flushing solution does not help return the fuel supply system to its original condition, you will need to contact a professional. They will perform diagnostics and provide comprehensive system maintenance using appropriate equipment.
What do Internet users think about gasoline additives for cleaning injector nozzles?
- Doesn't boost, but cleans “Castrol TBE has already been mentioned here. A 180 ml bottle will be enough to treat approximately 5 tanks (250 liters). Actively fights detonation and cleans the engine. An acquaintance who drove a Subaru Forester appreciated its turbo engine. Although the engine speed does not increase, the engine runs smoother and cleaner, and pulls more confidently. Although, maybe this is self-hypnosis.”
Hi-Gear Flush Fluid
Hi-Gear is a washing fluid with a “soft” effect. Its main difference is the complete absence of harm to the injectors and the engine itself. Can be used multiple times throughout the year. At the same time, professional liquids can cause some damage if used frequently. Well suited for removing hard tarry deposits. The composition does not include any aggressive substances. Therefore, no harm will be caused to various polymer parts. Used in diesel engines.
Are additives always beneficial?
We purchased a new car
. Or bought a used one in Europe, where the fuel is of excellent quality. It has a pristine fuel system. After refueling, add a cleaning additive to the fuel. It doesn’t matter how often, the main thing is periodically. The entire system, from the tank to the nozzle, is constantly flushed and is in a clean, working condition. If you do not refuel with “left” fuel, using an additive can ensure trouble-free operation of the injection system for several years.
We didn't buy a new car
. She has already managed to “run” along our highways and tasted Russian gasoline. We do not know whether the previous owner monitored the condition of the fuel system. Most likely no. At the bottom of the tank, on the filter mesh, a thick layer of sediment has accumulated, consisting of resinous substances and mechanical impurities. On the advice of the seller, we add an additive. It, as written in the instructions, dissolves resins perfectly. Only first, not in the nozzle, but in the tank. If the tank has never been cleaned, bitumen-resin slurry with asphalt flakes enters the fuel line, destroying the equipment and completely clogging the injectors. The consequences of such an action are worse, the more contaminants settled in the tank. As a result, you may end up having to replace the fuel pump, catalyst, control system sensors, and clean the injectors with ultrasound.
Summary: the use of a fuel additive to flush the injector is indicated for a car with a clean fuel system. And it is not recommended if dirt has accumulated in the tank.
