Additives for hydraulic lifters
Content
If, when starting the engine or even after it has completely warmed up, the hydraulic compensator makes a knock, then it is faulty. This problem is familiar to many motorists. You can, of course, contact the service or sort out the motor yourself, but this will take time and significant financial investments. Or you can try to solve the problem in a simpler way, and the hydraulic compensator additive will be the main assistant in this.
Problems with hydraulic lifters
When the engine is cold, knocking can be caused by the following reasons:
- the appearance of contaminants inside the hydraulic compensator itself due to the use of low quality engine oil or tightening with its replacement;
- excessive thickening of the oil, which takes time to fill the cavities;
- Plunger worn or seized.
When the engine is warmed up, knocking may appear for the following reasons:
- improperly selected oil;
- wear or contamination has led to seizure of the plunger pair;
- foaming of oil by the crankshaft or ingress of moisture into the engine;
- high oil level.
It is quite possible to eliminate all this on your own, without contacting a service center. However, if you doubt your abilities, it is still better to trust the specialists.
How an additive will help remove the knock of a hydraulic lifter
Often, if the cause of the knocking noise is caused by a dirty filter or oil passage, the most effective way is to use an oil additive that removes the dirt, restores oil flow and makes it a little thicker, compensating for wear on parts.
The main purpose of the additive is to cleanse valves and channels, which will improve the normal operation of the system and eliminate extraneous noise.

The main functions of the additives are: eliminating extraneous knocking, improving the lubrication of the internal elements of the car, cleaning from contaminants and preventing their appearance. The universal property of the additive is that it effectively cleans even the thinnest channels, so that a sufficient amount of lubricant gets into the hydraulic compensator and it stops knocking.
A "hot" additive is applied, after which the engine must be turned off and the cleaner filled in. We take 1 package of additives for 3-5 liters of oil, depending on the brand of the car and the composition of the selected additive.
Top 5 hydraulic compensator additives
Liquid moly
A universal additive from a German manufacturer, used in both gasoline and diesel engines, is compatible with all modern oils. 300 ml of the additive is designed for 6 liters of engine oil. Can be used during oil changes or topped up with what is. The cost of a 300 ml jar is quite affordable - from 650 to 750 rubles.
Steal
The stop noise of the Ukrainian manufacturer is distinguished by a wide selection of additives, which can be divided into three categories: classic additives, fortified ones and additives of the 3rd generation. These additives are more suitable for sports cars and cars with a powerful engine. It is produced in tubes of 8-9 ml, the average cost of which is about 1000 rubles.
Wagner
German additive, a relative newcomer to the auto chemistry market. Of the distinctive features, one can note its composition, the components of which not only eliminate contamination of the oil system, but also have protective properties, which leaves the engine clean for a long time. But the price from this manufacturer for such quality is quite high. For 250-300 ml, you will have to pay from 2300 rubles.
Wynn's
In addition to the main functions, this additive from the Belgian manufacturer can be used to stop the leakage of engine oil. The use of this additive also results in a significant reduction in fuel consumption. The cost ranges from 300 to 800 rubles. for 325 ml.
Opposite
This Russian company provides a wide range of additives for motorcycles, gasoline and diesel cars, commercial vehicles and trucks. 1 bottle is used for 5 liters of oil, the cost of 1 bottle is from 600 to 3700 rubles. depending on the size of the vehicle.
How long is it worth waiting for the result
As a rule, a noticeable decrease in the knock of the hydraulic compensator is noted almost immediately after the addition of the additive, however, the full effect occurs after about 500 km of run.
Questions and answers:
Which additive is best for hydraulic lifters? The easiest way in this case is to use Liqui Moly Hydro-Stossel-Additiv. It cleans the oil passages, improving oil flow to the expansion joints.
How to use a hydraulic lifter additive? The container is shaken. The engine is shut off. An additive is added to the oil (300 lm per 6 liters of oil). In some cases, additional flushing will be required.
What to pour when the hydraulic lifters knock? In these cases, special flushing additives are used. They are usually used before changing the oil. The additive cleans the channels from carbon deposits and improves oil circulation.
