10 best additives for the engine

The petrochemical industry does not forget about motorists, producing various additives to extend the life of vehicles. The appearance of miraculous additives was ambiguously perceived by domestic motorists. Someone they helped to avoid costly repairs, and someone is sure that he threw money away. Not in all cases the additives can help the car owner, especially if the engine of the car is completely “killed”. Most often, the additives are useful prophylaxis or minor repairs of the motor still working. In addition, today the field of activity of additives is increasingly narrowing, as is usually written in the attached instructions. Unfortunately, our people have no time to thoroughly study the recommendations of the manufacturer, which is why users do not get the expected effect. What additives are currently considered the best for the engine? Here it is worth paying attention to a few points.

1. The first step is to determine the purpose of the purchased additives. If the engine "cries with oil tears", then you should not increase its compression. It is better to turn your eyes to special sealants.
2. The problem of noise and smoke can also be solved with additives for the engine. You only need to choose the appropriate option for your motor. It is necessary to take into account not only the type of power unit (gasoline, diesel), but also the basis of the oil ("mineral water", semi-synthetics, synthetics).
3. When diagnostic studies show that the power unit is left to live is not too many hours, then overhaul can remetallizant additives. They contain metal particles that form a durable layer on the surface of worn parts. As a result, gaps are reduced, the motor starts up better, and he gets a thrust. But the effect of remetallizants is limited to several tens of thousands of kilometers.

Our review includes the best additives for engines of different types. The rating is based on feedback from domestic car owners.

The best additives for gasoline engines

A distinctive feature of gasoline engines is the high temperature in the combustion chambers. Therefore, the additives must have heat resistance, as well as the coatings and films formed by them.

3 Hi-Gear SMT2

To extend the life of old gasoline engines will help additive Hi-Gear SMT2. The composition is added to the engine oil, which leads to the optimization of friction between parts and components. This is especially useful for worn piston and connecting rod groups, where large gaps are formed. The additive has an innovative conditioner SMT2, thanks to which it is possible to reduce the dynamic loads on important parts of the power unit. As a result, the old motor gets a second youth. Numerous tests have shown that durability can be increased by 2-2.5 times. This means that the overhaul can be slightly delayed.

Differently motorists speak about the additive Hi-Gear SMT2. Some are praised for increasing the service life of the engine, easier starting, fuel economy. Others are unhappy with the short-term effect of use, sometimes there are no improvements in the operation of the motor.

2 Liqui Moly CeraTec

Reliable protection of the gasoline engine provides the additive German Liqui Moly CeraTec. The basis of the additive was the molybdenum-organic complex, which is supplemented with ceramic microparticles. Regular use of the composition allows to increase the resistance to wear of metal parts and mechanisms. The anti-friction effect is achieved by smoothing the microscopic irregularities inside the engine, which favorably affects the slip. The duration of the additive is maintained for 50 thousand kilometers. After adding the composition to the oil there is a decrease in the consumption of lubricant and gasoline, the power unit is quieter.

Domestic motorists in a review indicate such strengths of the additive Liqui Moly CeraTec, as the efficiency of the motor, the increase in resource, long-term action. Of the disadvantages of a high price, it is not always possible to improve the engine performance.

1 SUPROTEK Tribotechnical composition "Active" (Asset Gasoline)

The domestic manufacturer made the best repair additive that protects the engine from wear. This is SUPROTEC Tribotechnical composition "Active" (Active Gasoline) to be added to the oil. The composition is intended for use in gasoline cars that have a mileage of up to 50,000 km. It can be used both in conventional aspirated and in forced and turbocharged power units. Additive does not change the properties of the lubricant, and contributes to the formation of new films that reduce friction. The special structure of the new surface layer partially restores worn parts and optimizes the gaps between the rubbing elements. The use of the composition increases the service life of the gasoline engine, protects the nodes under increased load.

Car owners in the reviews mention such positive aspects of the application of additives, such as facilitated start of the cold engine, a slight decrease in the consumption of oil and gasoline. The hopes of some motorists this composition did not justify.

Top Diesel Engine Additives

Diesel engines eventually experience problems with compression, increasing noise and smoke. When buying additives should find out the possibility of their use in diesel engines.

4 RESURS DIESEL

For the restoration of worn-out diesel engines, the domestic manufacturer offers RESURS DIESEL remetallizer. Additive is designed to add to the new engine oil during the replacement of lubricating fluid and filter element. The composition is resistant to centrifuges and turbines, preventing dry friction during cold start or under heavy loads. The manufacturer promises to increase the service life of the engine up to 20 thousand km, and the turbocharger up to 1 year. Among the beneficial properties of remetallizant, it should be noted that oil is sootted (up to 5 times), fuel economy (up to 10%), compression increase (up to 40%). It is recommended to use an additive when running a car more than 60 thousand km.

Users managed to appreciate the quality of the RESURS DIESEL additive. In many cases, diesel engines become more powerful, quieter, run better. Some car owners are skeptical about the possibilities of additives, since no significant improvements were found.

3 AC-627

The domestic company ASTROhim has created the most affordable additive for engines AC-627. It is designed to add diesel and gasoline engines to the oil (volume up to 6 liters). It is recommended to use the new composition in cars with high mileage.First of all, the beneficial effect of the additive is manifested by the elimination of gaps, which are the result of natural wear of parts. This is especially important for sealing pistons in diesel engine cylinders. The composition contributes to the restoration of working compression in cars and trucks, and in agricultural, special, construction equipment. It is possible to apply the additive with any types of lubricants, in the course of work the composition maintains an optimal balance of engine oil.

Domestic car owners speak positively about the availability and possibilities of additives AC-627. It quickly increases compression, improving start of the diesel and increasing its power.

2 SUPROTECH. Tribotechnical composition "Active" (Active Diesel)

A unique triboseplate of finely dispersed mineral powders of a certain composition and strictly selected fractionation is able to gradually form a layer resistant to friction and wear on the friction surfaces of the engine. Unlike conventional additives for oils, which simply increase the slip and should be present in the lubricant all the time, it is recommended to use it either once or periodically, but with large intervals. In addition, the positive effect of the treatment with the drug manifests itself in several directions: first, carbon deposits are removed from the engine parts, which leads to improved working conditions and wear reduction, then a protective nanofilm is formed, which has a low friction coefficient, and in parallel, the scratches occurring during operation engine

Thus, the Active Diesel tribotechnical additive is an effective “medicine” for a motor that already has a significant degree of wear, but is still quite lively: there is no critical oil consumption, high pressure crankcase gases and compression in the cylinders reaches at least 8 kg / cm². The owner of such a car can expect a significant improvement in its characteristics. Judging by the numerous reviews, it is reflected in a noticeable decrease in fuel consumption and engine noise, an increase in its service life, an increase in the responsiveness of the car to the pedal and acceleration dynamics. But the heavily worn “heart” of the additive, most likely, will not save, and the manufacturer honestly warns the buyers about this.

1 Bardahl Full Metal

The most modern development of the Belgian manufacturer introduced in the additive Bardahl Full Metal. The composition helps to prolong the life of a diesel engine with heavy wear. Thanks to the patented Bardahl Polar Plus technology, the adhesion of the oil film was improved. Even after a long standing in the cold, the oil remains on the parts, reducing the gaps in the piston group. Also, the oil film reduces friction in such loaded nodes as the crankshaft and camshaft. The use of the additive has a positive effect on fuel economy and oil consumption. In the exhaust gases of diesel cars, the concentration of soot and burning is reduced, the smoke becomes lighter. It should be noted that there are no solid particles in the composition; therefore, the oil filter and the internal cavities of the motor do not become clogged.

In reviews, motorists praise Bardahl Full Metal additive for improving the start of a diesel engine, increasing its power, reducing smoke. The main disadvantage of the additive is the high price.

Top Sealants

Any engine with oil leaks over time. It is best to solve this problem by replacing rubber products. But in some cases, the introduction of additives, sealants will be faster and cheaper.

3 AC-625

Domestic additive AC-625 will help to quickly and cheaply eliminate leaks of engine oil. It is suitable for both petrol and diesel engines with turbocharging. Means effectively fights lubricant leaks due to softening of rubber gaskets and seals. The sealant does not have a side effect on the operation of the engine oil, and prior to replacement it will prevent leaks in the power unit. One bottle is enough to mix with 6 liters of oil. It is best to add the additive during the replacement of the lubricating fluid and the filter, but only after the engine has warmed up to operating temperature. The composition can be used with any type of motor oil.

Car owners in the reviews mention such advantages of the domestic additive AC-625 as availability and efficiency. Among the shortcomings, users note the fragility of the seal.

2 Liqui Moly Oil-Verlust-Stop

Liqui Moly specialists created a fast and effective remedy for eliminating engine oil lines leaks. Additive Oil-Verlust-Stop not only copes with cracks in the hoses, but also makes other rubber parts (seals, gaskets) more elastic. Favorably affects the use of the composition and to reduce noise, engine opacity during operation. This is due to the improved properties of the oil wiper caps and hydraulic compensators. You can use the composition in gasoline and diesel engines, the volume of the bottle is enough to mix with 3-4 liters of engine oil. The first signs of restoration of tightness should be expected after 600-800 km of run.

Experienced drivers have noticed a number of positive points from the use of additives Oil-Verlust-Stop. Oil leaks are eliminated, noise and smoke are reduced, the durability of oil lines increases. Unfortunately, not all defects of oil hoses can be leveled.

1 Hi-Gear "Stop-leak" for the engine

An effective additive to eliminate engine oil leaks is the Hi-Gear "Stop-Leak" composition. The manufacturer has patented a special polymer formula that stops the leakage of engine oil through gaskets and gaskets. The additive is introduced into the lubricating fluid, where it is evenly distributed. Together with the oil, the unique composition penetrates through microscopic holes and cracks. Upon contact with air, the additive is polymerized, thereby restoring the engine tightness. The hardened part of the additive firmly and for a long time ensures reliable connections. The additive molecules remaining in the oil will work until scheduled maintenance, preventing the emergence of new leaks.

Motorists speak positively about the performance of the tool, especially helps "Stop-leak" when worn front and rear crankshaft oil seals.
