8 best piston ring decarbonizers

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

As the engine runs, the piston rings and oil scraper rings become covered with carbon and soot deposits. This plaque makes it difficult for them to move, making it difficult to prevent oil from entering the combustion chambers and create compression. Various preparations have been developed to remove coke. We have studied customer reviews, as well as product characteristics, and present you a rating of the best means for decarbonizing piston rings. This will help you to select a product for quality and price, as well as the way it is used on the car.

Shumma EX Engine Conditioner

Rating: 4.9

The first place in the rating is taken by a product from a Japanese manufacturer Mitsubishi, which is recommended for the entire model range of this brand. The decarbonizer is supplied in a pressurized can and is equipped with a tube for easy feeding into the candle wells. The substance resembles foam in consistency. It is blown into the cylinders, and the holes are closed with old candles. Buyers in the reviews like that it works fast enough and will have to wait about 30 minutes. The combustion chamber is cleaned completely, including the piston rings and walls. Shake the can a little before applying. True, after starting the engine, there is very thick smoke, so the decoking procedure should be carried out only on the street, and not in the garage.

Our experts put the Japanese product in first place in the ranking, since the decarbonizing foam penetrates deeply into the parts and cleans the piston rings even from the back side, significantly increasing their mobility. Reviews also show that it does not harm the paint in the sump, unlike other products that raise the top layer of the coating in the crankcase.

Advantages

• the engine picks up speed better;
• thrust is 2000-3000 higher;
• after use, there is still a little means for preventive use;
• compression increases.

disadvantages

• the tube from the set is short, it is better to buy a longer one separately;
• the oil level may subsequently drop by 2 mm;
• high price;
• will not help if the lubricant consumption is 1 liter per 1000 km.

Kangaroo icc300

Rating: 4.8

The second place in the rating is given to the 'Kangaroo' product, which is available in a 225 ml bottle. It can be poured into candle wells or through holes from nozzles. Some of them even tried to clean valve seats and dimes. The product can be used alone or in conjunction with BG 109. Customers in reviews like that after using this tool to decarbonize rings on pistons, the spark plugs remain clean despite running 5000 km. The central insulator is not covered with soot at all. This effect facilitates easy starting of the motor from the first spark.

This is the best cleaner for de-carbonization of engines that have a small mileage of up to 70,000 km. The tool is more used for prophylaxis, removing even the thinnest film of plaque. This helps to keep the cylinder walls close to ideal. Subsequently, if you use the agent at each oil change, during the overhaul, you will not have to grind the cylinders, but only replace the piston rings with a larger size.

Advantages

• also suitable for cleaning the carburetor;
• fills the chamber well;
• extends its action to the valve pennies;
• washes away sludge residues.

disadvantages

• not applicable in advanced cases or after a run of 500,000 km;
• flushing is still required before changing the oil.

Laurel ML-202

Rating: 4.7

Next in the ranking is a decarbonizing agent from a domestic manufacturer. It comes in 185 and 330 ml bottles with a syringe and tube for easy refueling. The second bottle is enough for an internal combustion engine with a volume of more than 2 liters. The creators of the piston ring decarbonizer claim to have sold 4,000,000 units. The liquid has a rare consistency and is poured through compartments with nozzles or candles. This restores power and extends the life of the powertrain. Drivers in the reviews say that after going through the decarbonization procedure, the engine began to start much easier despite the night idle time. This chemistry is actively used on cars produced in 1994-1995 and they can do without major repairs for some time.

The product for de-coking rings in a piston system was included in the rating due to its affordable price compared to imported counterparts. Due to its increased fluidity, the substance is suitable for V-shaped engines or for carrying out the procedure on a car standing on a slope. If there is a recess on the piston crown, then the drug will flow into it.

Advantages

• safe cleaning of pistons, rings, combustion chambers;
• normalizes compression for each cylinder;
• restores power characteristics;
• reduces fuel consumption;
• cold start becomes much easier.

disadvantages

• for each engine, an individual calculation of the amount of funds is needed;
• the composition is very harmful to human skin – care is needed;
• strong unpleasant odor.

Greenol Reanimator

Rating: 4.6

The Tomsk development 'Greenol Reanimator' continues the rating. It is a highly active decoking agent. It safely removes carbon deposits, washes piston rings, increases their mobility (if fired), and facilitates the flow of oil back into the crankcase. A product for decarbonization is produced in a plastic bottle, so it can be ordered by mail on the Internet, since the container will not be damaged even with inaccurate delivery. The substance is effective at eating up to 200 ml of lubricant for every 1000 km of run. The paper box contains detailed instructions, and buyers in the reviews share that the decoking procedure can be completely carried out in the garage without the involvement of specialists.

The product is notable for its volume of 450 ml, which is 1.5-2 times higher than the offers of other manufacturers, for which the product is placed in the rating. Such a container is beneficial for auto repair shops that regularly carry out the procedure for decoking the rings of the internal combustion engine. One bottle is enough for two 1.5-liter engines, so you can buy the drug for two with a neighbor who has the same problem.

Advantages

• an increase in traction is felt;
• promotes the resumption of smooth motor operation;
• gray smoke ceases to flow from the exhaust system;
• respect for seals and rubber bands.

disadvantages

• for a week in the salon there is an unpleasant smell from the burning out of the product;
• at start-up after application of the drug, internal combustion engine 'troit' or 'pyateritis';
• high price;
• some in the reviews complain about the raised paint in the pallet.

GZOX INJECTION & CARB CLEANER

Rating: 4.5

The TOP-5 includes a Japanese piston system decarbonizer produced in the form of mousse. It is fed through a thin tube. Allowed to be used for carburetors, cleaning the fuel system, internal combustion engines of motorcycles, injection installations. The container contains 300 ml of the substance. After use, the product improves the throttle response of the motor. The manufacturer recommends applying it every 10,000 km to delay overhaul. To clean the fuel system, the agent can be applied through the throttle valve.

In our opinion, auto chemistry has earned a place in the ranking of the best for decarbonization, due to its instant action. It begins to remove coke from the first minutes of application and you will have to wait a maximum of 5-6 minutes (just to wrap candles / coils and connect high-voltage wires). This is a great option when there is no time to wait 30-60 minutes. You can hold the container at any angle for spraying, which is important for a complex engine shape with a non-standard arrangement of wells.

Advantages

• the product is produced in Japan;
• affects carbon dioxide deposits and resins;
• applicable to injection and carburetor ICEs;
• suitable for motorcycles.

disadvantages

• high price;
• cannot be used on machines with direct fuel injection;
• not compatible with diesel;
• emits a strong odor.

Edial

Rating: 4.4

Sixth place in the ranking for autochemicals from the Edial brand. The decarbonizer is available in 50 and 100 ml containers for passenger cars and commercial vehicles. There is a separate series in 200 ml bottles with a special concentration for large trucks. On request, the manufacturer supplies other packaging that is convenient for customers. The substance actively penetrates to the underside of the piston rings, removes dirt from the grooves, cleans the seat seats. Buyers in the reviews are glad that after decoking, they do not need to change the oil. Particles of the agent stick to the carbon deposits on the rings and pistons, and subsequently burn out along with the soot. The engine crankcase remains clean.

The product is listed by us in the rating due to its ease of use. To carry out decarbonization in the piston group, you do not need to unscrew the candles or remove the coils. The product is simply poured into fuel. One bottle is required to be diluted in 40-60 liters. The brand of gasoline does not matter. The fuel will itself deliver the cleaner to the piston rings in the combustion chamber. Valves with seats will be cleaned along the way.

Advantages

• suitable for gasoline and diesel vehicles;
• saving time when using;
• no subsequent oil change required;
• can be carried out at any time, without adjusting to the oil change schedule during maintenance.

disadvantages

• it is required to fill in only before refueling at a gas station so that the gasoline mixes well;
• does not dissolve dirt in the tank.

Verylube anticox

Rating: 4.3

We gave the penultimate place in the rating to a product for decoking piston rings from the Verylube brand, which is a subsidiary of Xado. The substance is designed to remove tar deposits and carbon deposits in the cylinder-piston group. The agent is fed into the warm engine through the nozzle sockets. For this, there is a coiled hose under the cylinder cap. Car chemicals are safe for rubber seals and oxygen sensors. It will not damage the catalytic converters behind the lambda probe. Reviews show that the drug does its job well. Another plus that customers like is economical consumption – 5 seconds of feeding into each 'pot'. With this calculation, the funds will be enough for 5 four-cylinder internal combustion engines.

This tool deserves a place in the rating of the best, since it is suitable for internal combustion engines operating on both gasoline and diesel fuel. This is a rarity among foam-type preparations. The fast-acting composition is designed for old coke on rings and pistons from diesel fuel, so it will be of interest to owners of this type of transport.

Advantages

• no oil change required;
• one bottle is enough for 20 cylinders;
• restores the mobility of the rings;
• compression is leveled;
• the volume of the motor is reduced.

disadvantages

• it is necessary to turn the crankshaft with a starter with open wells;
• when it gets on the paintwork, it corrodes it.

Wynns Combustion Chamber Cleaner

Rating: 4.2

Completing the rating of the best products from the Belgian company Wynns. The additive is available in 400 ml packs. It is designed for direct feed into the combustion chamber through a vacuum hose through a medical dropper with a dispenser, but after that the candles and oil do not need to be changed, which customers like in the reviews. Nothing goes into the crankcase – everything burns out and goes through the manifold into the muffler. After the procedure, it is enough to drive 5 km or burn it on the spot, so that the swollen soot burns out and translucent smoke begins to flow out of the exhaust.

The feature of this tool for removing carbon deposits from rings in the piston system is a special development for Russian gasoline. Representatives of the Belgian company took samples in different regions in order to create a product exclusively to combat oils and impurities present in domestic fuels. After a thorough study of the chemical analysis of gasoline, the company has released a unique formula. Another plus of the product for decarbonizing is the relatively affordable price, despite the imported quality. But it is not possible to buy it in any city of Russia, which is why it is placed in the last place in the ranking.

Advantages

• actively fights against sticking of piston rings;
• improves valve performance;
• eliminates engine detonation;
• not harmful to the catalyst.

disadvantages

• cannot be used on diesel engines;
• not everywhere you can buy;
• complex supply of the substance through a dropper dispenser;
• mixing with gasoline is prohibited.
