In recent years, a huge number of various additives and additives to oil have appeared on the shelves of car shops. However, listening to the advice of friends and sellers, you should remember that improper use of such products can lead to negative results, up to the engine failure. Therefore, it is necessary to clearly formulate the tasks and ways to solve them in relation to the specific situation and condition of the engine.
Types of additives added to the oil:
Run-in additives that accelerate and improve the quality of lapping of friction surfaces in new engines during run-in
Cleaning additives used to remove tar deposits in heavily polluted engines
Additives that reduce friction and, consequently, increases the efficiency of the engine
Restoring additives that build up a layer of metal or ceramic on worn parts of the engine friction pairs; additives of this type can significantly reduce oil consumption, “revive” the engine and increase its mileage before major repairs
In addition, there are additives with other application technologies that are not added to the oil, but are introduced into the running engine, for example, through the carburetor.
Keep in mind that the first filled additive can negate the effect of the second, and the simultaneous use of two different additives can cause the engine to fail. If you want you engine works perfect and long period you should use only the best oil additive, you can watch some review and choose the best one for you at the iasecon.net website.
The oil in the engine makes a cycle, so the products of its oxidation and wear gradually accumulate. Some of them settle in the crankcase, and the other part constantly circulates with the oil. Under the influence of high temperatures and chemical transformations, accumulated dirt gradually settles on various surfaces of the engine in the form of varnish, coke, and resinous deposits. At the same time, heat exchange deteriorates, anti-wear and anti-friction properties of the oil decrease, its corrosion activity and engine wear increase. The color of the oil becomes darker.
To get rid of carbon deposits and minimize their negative effects, the engine must be cleaned from time to time. This should be done before changing the oil. The frequency depends on the condition of the engine and its operating mode, as well as on what oil is poured. The worse the condition of the engine, the harder the working conditions of the car and the easier (cheaper) the oil, the more often you need to wash the engine. If the engine is in good condition, use of synthetic and semi-synthetic engine oils to wash the engine less often – every 3-5 oil changes.
When choosing washes, it is better to give preference to proven products. A good range of flushes has a German company Liqui Moly. For example, the gentle ol-Schlamm-Spulung wash, Engine Flush cleaner, and motor Clean and Motor Protect additive complexes allow cleaning and protecting the engine from deposits and wear for 50 thousand km.
One of the components that provoke the formation of deposits and dirt are the products of engine wear, so in addition to cleaning it from deposits, it is very important to reduce its wear. However, according to the developers of new engine oils and additives, even synthetic engine oil of the highest classification can prevent engine wear by only 70 %. With this data, high-quality anti-wear additives (friction modifiers) will never hurt.
Keep in mind that unverified cheap additives have only a primary, short-term effect of reducing wear, and in further operation can lead to increased oil oxidability, provoke corrosion or cause other undesirable changes.
You should know that the same additive can not be added to both engine and transmission oil.
If the ads for the additive talk about its engine-transmission “versatility”, then it is better to refuse such a product. Transmission oils work under high loads, so when developing additives to them, the emphasis is on protecting the transmission from bullying. Sulfur-containing additives are better able to cope with this task.
