Nozzle cleaners
Content
The question of how to clean injectors often worries both owners of cars with gasoline and diesel engines. After all, in the process of operation, they naturally become polluted. Currently, there are popular means of cleaning nozzles from carbon deposits - "Lavr (Laurel) ML 101 Injection System Purge", "Wynn's Injection System Purge", "Liqui Moly Fuel System Intensive Cleaner" and some others. In addition, there are three cleaning methods that affect whether the nozzles need to be dismantled or can be cleaned without removing them. It is the quality of cleaning and the purpose that the liquid for cleaning the injector (the so-called Injector Cleaner) will differ.
Nozzle cleaning methods
Among the variety of products, the better to clean the nozzles, there are two types that will be designed for one of the basic cleaning methods, since different cleaning compounds will be required. So the methods are:
- Pouring the cleaning agent into the fuel tank. Auto shops sell injector cleaning fluids designed for 40 ... 60 liters of fuel (in fact, for a full tank of a modern car). Their application consists in simply adding an additive to the tank, and although they perform a wider function - they increase the octane number and remove excess moisture, they also clean the fuel from carbon deposits and deposits quite effectively. This method has two advantages - simplicity and low cost. There are also two disadvantages. The first is that all the dirt in the tank will eventually clog the fuel fine filter. The second is a large number of fakes that are ineffective.
- Washing the nozzles in the cleaning plant. Two options are possible here. The first - with dismantling, the second - without. Dismantling the nozzles means cleaning them on a special ramp. And the option without dismantling means that the fuel rail is disconnected from the fuel lines and the tank. After that, a special injector cleaner is poured into the cleaning unit, and it is connected to the fuel rail on the car. The composition passes through the nozzles and cleans them. In the case of using original high-quality nozzle cleaners, in most cases a good result is noted. The cost of the procedure is acceptable.
- Ultrasonic cleaning. The most expensive, but also the most effective method. Cleaning agents are not used in this case, however, this method is perfect for extremely dirty injectors, both gasoline and diesel. For ultrasonic cleaning, the nozzles are dismantled and placed in a special bath. The procedure is available only at a professional service station.
Depending on what method is planned to be cleaned, a means is also chosen to clean the nozzles. Therefore, they are also divided into classes.
Such reasoning is valid both for machines with modern multiport injection, and with the older system - monoinjection, where only one nozzle is used. Although in the latter case it is easier to clean it.

Rating of popular means
In ordinary retail outlets and online stores, you can currently find many different, both well-known and not so well-known, nozzle cleaners, but most of them have conflicting reviews and tests on effectiveness. We tried to evaluate nozzle cleaners as objectively as possible and made a rating based on positive and negative feedback from real car owners who used or tested these compounds at different times. The rating is not commercial in nature, so it's up to you which tool to choose.
Wynn’s Injection System Purge
The tool is positioned by the manufacturer as a cleaner for the elements of the fuel system of gasoline engines, including the injector. As in the previous case, washing with Vince is carried out at a cleaning plant, but already from any manufacturer. The procedure is standard, you need to disconnect the line and the fuel tank, and clean the injector nozzles using the installation at running internal combustion engine, since cleaning the injector by Vince removes carbon deposits not by flushing, but by burning!
The manufacturer claims that the cleaning agent, in addition to its immediate functions, also cleans the intake tract, fuel distribution line, fuel pressure regulator and pipelines from harmful deposits. In addition, the tool has a decoking effect. Please note that the liquid is quite aggressive, so when connecting, you need to use hoses that are resistant to aggressive elements, and the washing machine must be connected exactly to the frame, excluding rubber fuel hoses from the system.
Real tests have shown a fairly high efficiency of its use. Internal combustion engines, even with a mileage of 200 thousand km, show the best dynamics and get rid of failures when revving. In general, reviews about the Vince nozzle cleaner are mostly positive.
Wynn's Injection System Purge is available in one liter cans. The article number is W76695. And the price for the above period is about 750 rubles.
LIQUI MOLY Fuel System Intensive Cleaner
This cleaner can be used for cleaning gasoline carburetor and injection engines (including those with single injection). In accordance with the description, the composition removes deposits from injectors, fuel rail, lines, and also removes carbon deposits from valves, candles, and from the combustion chamber. Please note that Liquid Moli for cleaning nozzles is sold as a concentrate, in a 500 ml can. This volume is needed dilute with gasoline, preferably high-octane and high-quality, the cleaning efficiency depends very much on the last factor.
To the mentioned 500 ml of concentrate, you need to add 4 ... 4,5 liters of gasoline in order to get about 5 liters of the finished cleaning composition. To flush an internal combustion engine with a volume of 1500 cubic centimeters, approximately 700 ... 800 grams of the finished liquid is needed. That is, in order to get such a volume, you need to mix about 100 grams of concentrate and 700 grams of gasoline. The cleaning mixture is used in a special washing unit for washing nozzles on the ramp. Indicates the installation type LIQUI MOLY JET CLEAN PLUS or other similar equipment.
Real tests showed very good application results. So, up to 80% of resinous deposits can be washed from the nozzle, and the remaining pollution softens very much, and during the operation of the internal combustion engine it can be removed on its own. If you wash the nozzle for a long enough time (for example, up to three hours), then you can achieve its complete cleansing. Therefore, the tool is definitely recommended for purchase.
Cleaner Liqui Moly Fuel System Intensive Cleaner Sold in two volumes. The first is 5 liters, the second is 1 liter. Accordingly, their article numbers are 5151 and 3941. And similarly, the prices are 7500 rubles and 800 rubles.
Fuel system cleaner for gasoline engines Suprotec
The fuel system cleaner "Suprotek" of domestic production is rightfully very popular with motorists. This is due to its high efficiency, namely, high-quality cleaning of both cold and hot internal combustion engines. This is made possible by its balanced composition, which includes the appropriate additives, including additional oxygenates, which provide an increase in the oxygen content in the burned gasoline. And this has a positive effect on the combustion of fuel at high temperatures, that is, high-temperature cleaning of the fuel system elements. At the same time, the Suprotec cleaner contains no harmful components, such as methanol, metals, benzene and others. Accordingly, the value of the octane number does not go beyond the permissible limits. In addition, with a load on the internal combustion engine, the cleaner is able to reduce fuel consumption by approximately 3,5 ... 4%, and in idling mode - up to 7 ... 8%. In the exhaust gases, the content of residual hydrocarbons is significantly reduced, the presence of which indicates the degree of contamination of the internal combustion engine.
Real tests have shown quite good performance. namely, when driving at low speeds (first-second gears and medium engine speeds), the Suprotec fuel system cleaner provides a smooth ride without twitching and jerking. However, it is worth noting here that the general condition of the fuel system as a whole and its individual elements, namely, also affects the behavior of the car. For example, you need to check the condition of the fuel filter. Therefore, the cleaner is unequivocally recommended for purchase by all owners of cars with gasoline ICE on fuel of any brand.
Sold in a 250 ml bottle. According to the instructions, one bottle is enough to dilute in 20 liters of gasoline. The article of such a package is 120987. Its price for the above period is about 460 rubles.
LAVR ML 101 Injection System Purge
One of the most popular means in the domestic market. Independent tests have shown that the additive is able to wash up to 70% of carbon deposits on the nozzle (depending on its condition and age). To use this liquid for washing nozzles, a special installation "Lavr LT Pneumo" is required. Accordingly, to use the tool, you need to look for a service station where this equipment is available, or buy it for yourself, or make such an installation yourself (unlike the usual one, you need to make it in order to connect a compressor to a container with cleaning liquid to create working pressure).
"Lavr 101" not only cleans nozzles well, but also reduces fuel and oil consumption, and also provides easy start-up in the cold season, increases the overall resource of the internal combustion engine. Real tests have shown that the product effectively cleans nozzles, therefore it has gained wide popularity among both ordinary car owners and car service workers involved in cleaning nozzles.
Cleaning agent Lavr ML 101 Injection System Purge is sold in a one liter package. It has an article - LN2001. The price of a nozzle cleaner as of the summer of 2020 is about 560 rubles.
Hi-Gear Formula Injector
This injector cleaner differs from the previous ones in that it must be poured into the fuel tank. The manufacturer reports that even one application is enough to remove carbon deposits on the injector. In addition, the additive provides lubrication of the needle valve of the injector, prevents it from freezing, extends the service life of injectors several times, eliminates detonation (the so-called "knock of fingers"), prevents the formation of deposits on the intake valves and carbon deposits in the combustion chamber.
As for the application, one bottle of 295 ml is enough to clean the fuel system of an internal combustion engine with a volume of up to 2500 cubic centimeters. It is desirable to fill in a full tank of fuel. There is also a large pack of 946 ml. It is designed for three cleanings of ICEs of passenger cars or two cleanings of ICEs of trucks.
Real tests of the use of the “High-Gear” nozzle cleaner showed its rather high efficiency. At the same time, it was noticed that its composition is quite aggressive, therefore it fights well with resinous deposits on the elements of the fuel system. As the manufacturer assures, in one cycle you can completely get rid of resinous deposits.
The most commonly purchased package of Hi-Gear Formula Injector has a volume of 295 ml. Her article is HG3215. The price of such a package is about 450 rubles.
also one popular remedy - Kerry KR-315 is also poured into the fuel tank and mixed with fuel. It is packaged in 335 ml bottles, the contents of which must be added to 50 liters of gasoline (if the tank volume of your car is slightly smaller, then not all the contents need to be poured out). According to the description, the additive cleans injector nozzles, dissolves deposits and resins, reduces rough engine operation, improves performance and reduces fuel consumption, protects the fuel system from corrosion and moisture. Interestingly, the tool does not harm catalytic converters. The big advantage of Kerry KR-315 is its low price.
Real tests of the cleanser showed that it can get rid of more than 60% of contaminants, including tarry and heavy ones. If you re-wash, then there is a chance that the nozzle and other elements of the fuel system will be completely cleaned. Therefore, despite the low price, the tool works quite effectively, and is definitely recommended for purchase by owners of cars with a gasoline engine and an injection system.
As mentioned above, the volume of the package is 335 ml. The article of the bottle is KR315. The average price of such a package is about 90 rubles.
Please note that the use of a particular cleaning agent largely depends not only on its composition and, consequently, on its effectiveness, but also on the condition of the internal combustion engine, fuel system, nozzles, quality of gasoline used, vehicle mileage and other factors. Therefore, for different motorists after using the same tool, the result may differ.
However, from general recommendations, it can be noted that additives poured into fuel are best used with high-quality gasoline. The fact is that low-quality fuel has little oxygen in its composition, so adding a composition to it that requires excess oxygen for its operation is detrimental to the internal combustion engine. This is usually expressed in his unstable work.
also, after pouring a cleaning additive, it is better to ride at high speeds in order to combine chemical and thermal cleaning. It is best to ride at high speeds somewhere outside the city. The effect of using the additive is usually felt only after all the fuel in the tank has been used (it must first be full). But watch out, so that before the end you have time to get to the gas station (or you can carry a canister of gasoline with you in the trunk).
If you have had any experience using these or any other nozzle cleaners, share your opinion in the comments.
Other similar nozzle cleaners
As stated above, the market for nozzle cleaners is quite saturated and only the most popular ones have been listed in the previous section. However, there are others, no less effective, which are presented below.
AUTO PLUS PETROL INJECTION CLEANER. The agent is intended for pouring into cleaning installations (for example, AUTO PLUS M7 or similar). Please note that a concentrate is sold in the bottle, which must be diluted 1: 3 with good high-octane gasoline (the quality of future cleaning depends on this). In general, the additive shows good results in cleaning nozzles.
STP SUPER CONCENTRATED FUEL INJECTOR CLEANER. This agent must be added to the fuel tank. It is sold in a 364 ml bottle, which is designed for 75 liters of gasoline. If you fill in less fuel, then the amount of additive must be calculated in proportion. note that This additive should not be used on vehicles with heavily contaminated fuel systems and/or fuel tanks.because she is very aggressive. Rather, it is suitable for cars with low mileage.
COMMA PETROL MAGIC. also added to the fuel tank. One bottle of 400 ml is designed for dilution in 60 liters of gasoline. Tests have shown that the additive works quite "softly", and it can be used in cars with a heavily contaminated fuel system and a contaminated fuel tank. Please note that the features of the additive include the appearance of flakes in the cleaning liquid, this is normal, you should not pay attention.
Toyota D-4 Fuel Injector Cleaner. Suitable not only for Toyota cars, but also for other injection vehicles. Its average efficiency is noted, and the cleaner is more suitable as a prophylactic.
RVS Master Injector Cleans Ic. Good injector cleaner. In addition to cleaning the injector, it also cleans the gasoline passing through the system. The effectiveness of the tool as a whole is rated as above average.
Carbon Clean. Liquid for washing injectors (MV-3 concentrate) MotorVac. also one popular cleansing liquid. Tests show its average efficiency, which, however, is offset by a small price.
VERYLUBE BENZOBAK XB 40152. It is rather a complex tool that not only cleans the injectors, but also cleans the entire fuel system, spark plugs. reduces fuel consumption, removes water from gasoline, protects parts from corrosion. Sold in a small tube of 10 ml, added to the fuel tank. In repair mode, it is designed for 20 liters of gasoline, and in preventive mode - for 50 liters.
Injector cleaner Abro IC-509. is also a complex cleaner. Packed in packages of 354 ml. This amount of additive is designed for 70 liters of gasoline.
Runway RW3018. In addition to cleaning injectors, it also cleans cylinder walls, spark plugs and other internal combustion engine elements. Its average efficiency is noted, which is compensated, however, by a low price. added to gasoline.
StepUp Injector Cleaner SP3211. A tool similar to the previous one. Cleans nozzles, candles, cylinders, facilitates the start of the internal combustion engine, removes carbon deposits. Rather, it can be used as a prophylactic on new and medium-range ICEs.
Mannol 9981 Injector Cleaner. It is an additive to gasoline, and it is recommended to add the agent to the tank BEFORE pouring gasoline. In fact, it is a complex cleaner that cleans not only injectors, but the entire fuel system, removes carbon deposits. More suitable for prevention. The 300 ml package is designed to dissolve in 30 liters of gasoline.
Lavr Injector Cleaner. also a very popular tool, and judging by the reviews, quite effective. Unlike the composition from this brand already described, this cleaner must be poured into the fuel tank; for this, a special convenient funnel is included. In addition to cleaning injectors, the product cleans intake valves and combustion chambers, promotes the binding of water in gasoline, and protects metal surfaces from corrosion. One package with a volume of 310 ml is enough for 40 ... 60 liters of gasoline.
In fact, there are a lot of such funds, and their full transfer is not worth it, and it is impossible, because over time new compositions appear on sale. When choosing one or another means, try to buy those that you have heard or read about. Do not buy cheap products of unknown brands. So you risk not only throwing money away, but also endangering the internal combustion engine of your car. If you know a good remedy that has not been mentioned, write about it in the comments.
Remember that cleaning additives in fuel must be poured, firstly, when there is at least 15 liters of fuel in the gas tank (and the amount of additive must be calculated in the appropriate proportions), and secondly, the walls of the gas tank must be clean. If you plan to use such funds as a preventive measure, then they should be used after approximately every 5 thousand kilometers.
Cleaning products for diesel injectors
The fuel system of diesel engines also gets dirty over time and debris and deposits accumulate in it. Therefore, these systems also need to be cleaned periodically. There are special tools for this. namely:
- LAVR ML-102. This is a product for flushing diesel systems with a decoking effect. It is noted for its very high efficiency in cleaning nozzles and a high-pressure fuel pump (TNVD). By the way, only the pump can be cleaned with a tool, it helps some people. The product is sold in jars of one liter. Its article on sale is LN2002. The average price of such a volume is 530 rubles.
- Hi-Gear Jet Cleaner. Diesel injector cleaner. According to the manufacturer's descriptions, it cleans the spray nozzles from resinous deposits. Restores the shape of the fuel spray jet and the dynamics of combustion of the mixture. Prevents the formation of deposits in the cylinder-piston group. Prevents wear of the plunger pairs of the fuel pump. Safe for catalytic converters and turbochargers. On the Internet you can find a lot of positive reviews about this tool. It is sold in packages of three volumes - 295 ml, 325 ml and 3,78 liters. Their part numbers are HG3415, HG3416 and HG3419, respectively. Prices - 350 rubles, 410 rubles, 2100 rubles, respectively.
- Wynns Diesel System Purge. Flushing diesel engine injectors. Designed for effective cleaning of the injection fuel system of diesel engines without prior disassembly using a special flushing fluid.

The price is about 750 rubles.
- Nozzle cleaner LAVR Jet Cleaner Diesel, diesel fuel additive. Domestic analogue, which is in no way inferior to imported samples. Cleans not only injectors, but also the internal combustion engine injection system. It is activated in areas of high temperatures of a heated internal combustion engine, therefore it is guaranteed not to clog the nozzles with impurities from the fuel tank, fuel lines and filters. Promotes the binding of water in the fuel, preventing the formation of ice plugs, protects against corrosion. It shows good results, therefore it is recommended for purchase, especially considering its low price. Packed in 310 ml cans. The item number is Ln2110. The price of the goods is 240 rubles.
- Liqui Moly Diesel Flushing. Diesel engine injector cleaner. The additive removes deposits on nozzles, in the combustion chamber and pistons. Raises the cetane number of diesel fuel. Provides a confident start of the internal combustion engine, optimal spraying of diesel fuel, due to which the power of the internal combustion engine increases, and the toxicity of exhaust gases decreases. Cleans the entire fuel system. Protects against corrosion. Improves the combustion process, reduces exhaust toxicity and increases the acceleration of the internal combustion engine. Interestingly, this additive is recommended by BMW for its diesel engines. The bottle is enough for 75 liters of diesel fuel. As a preventive measure, it is recommended to apply every 3000 kilometers. Packed in branded packages of 500 ml. The article of the product is 1912. The price is about 755 rubles.
As in the case of additives for gasoline ICEs, the use of one or another additive depends on a large number of third-party factors, such as the fuel used previously, the general condition of the injectors and internal combustion engines, the mode of operation of the engine, and even the climate where the car is used. Therefore, the result of using one tool for different car owners can vary significantly.
Hack and predictor Aviator
In conclusion, I would like to note that the effectiveness of the use of certain additives depends not only on their properties, but also on the condition of the injectors and other elements of the car's internal combustion engine (contamination of the internal combustion engine, fuel tank and fuel system). Therefore, additives added to the fuel, perhaps, are more suitable as a prophylactic. If the nozzles are significantly clogged, you need to connect the fuel rail to the cleaning unit and perform a liquid wash of the nozzle. If the injector is clogged critically, then only ultrasonic cleaning will help, it is carried out only in specialized service stations.
As for the cost of these funds for the summer of 2020 compared to 2018 (the time the rating was compiled), Liqui Moly Fuel System Intensive Cleaner in a 5-liter capacity has risen the most - by 2000 rubles. The rest of the nozzle cleaners have become on average 50-100 rubles more expensive, except for Suprotec - it has remained almost at the same price level.
