How cheap motor oil can ruin an engine

Many car owners, finding themselves in a situation where their income has fallen, seek to save on the maintenance of their car. Citizens buy non-original spare parts, and choose cheaper motor oil, sometimes forgetting that cheap is not always good. The AvtoVzglyad portal tells about the consequences of saving on lubrication.

Few people know, but the production of motor oil itself is a simple matter. The main components can be bought in bulk from refineries. It will not be difficult to purchase ready-made packages of additives, as well as various additives. A few smart technologists then easily combine these components to create an engine oil with the required performance.

That is why in the car markets and even in fairly large car dealerships, a large number of oils of different brands have appeared at an affordable price. Drivers are attracted by the low price, because sales are in full swing. Unfortunately, the consequences of using such a lubricant can be sad.

The thing is that the additives in the composition of such an oil can quickly develop, for example, under increased engine loads, and the lubricant will quickly lose its protective properties. If it is not replaced, engine parts will begin to wear out. At the same time, no control lamps on the dashboard will light up, because the lubricant level will be normal. The result is a situation where the motor suddenly suddenly starts to act up or completely wedges it.

Another serious problem with cheap oils is quality control. In small enterprises, it is not as strict as in large manufacturers. As a result, defective batches of lubricant get on sale, which bring the engine to a major overhaul.

The most dangerous thing is that it is almost impossible to recognize a threat when buying a canister. After all, it is opaque and sediment, which is the main criterion for marriage, is simply invisible.

This sediment absolutely does not manifest itself when it is in the bank. But when pouring into the engine, when pressure and temperature appear, the sediment begins its harmful activity. So the oil sharply loses viscosity, that is, it simply thickens, clogs the oil channels and sentences the engine to overhaul. By the way, the repair will be very expensive, because it is very difficult to remove the plugs that clog the oil channels.

In fairness, we note that in their price confrontation, even more expensive oils do not always become winners. The reason is the poor quality. And here a lot depends on the specific manufacturer of lubricants. Therefore, when choosing oil for your car, preference should be given to trusted companies with a good reputation. This problem is most acute for lubricants for modern imported engines.

Take, for example, our popular Renault cars. For the engines of many cars of this brand, released after 2017, oils of special specifications are required, in particular, ACEA C5 and Renault RN 17 FE. Well, at one time it was not easy to find them! The situation was noticeably corrected by the German Liqui Moly, which developed a new synthetic engine oil Top Tec 6400 0W-20, which is already being supplied to our country.

Based on the totality of its operational qualities, the novelty confidently passed all the tests and received the original approval of the Renault concern. It is designed for both diesel and gasoline engines equipped with particulate filters. Among the significant technical features of Top Tec 6400 0W-20 is the possibility of its use in cars with Start-Stop systems. Recall that in them, when starting the engine, it is extremely important to ensure instant oil circulation through all channels of its lubrication system.
