It happens that the engine suddenly begins to make strange noises on the way, and then it stops working altogether. After dismantling the unit during service, it becomes clear that the lubricant has turned into a black slurry. The AvtoVzglyad portal tells what happened and how to avoid trouble.
Of course, lubricant manufacturers run their products on test benches. If we take average values, it turns out: synthetics can withstand about 1000 hours, and “mineral water” will last up to 300 hours. After additions, they lose their properties and the lubricant itself “roasts” and thickens so that the oil pump can no longer pump it. The problem is that real operating conditions significantly lower these numbers.
Dangerous processes can cause various impurities to enter the engine. For example, combustion products of low-grade fuel, ordinary dirt and water, but also the remains of mining, which are not completely disposed of when replaced. Another reason is the depletion of the additive package, which occurs when the lubricant regularly wears out at high temperatures. For example, in traffic jams or when the driver is storming mountain serpentines, and even in an overloaded car.
Many write that they determine such problems the old fashioned way – a drop of grease on a piece of paper. It’s a delusion. According to a blur, not even a professional diagnoses impending disaster.
Therefore, first remove the filler cap and inspect the lower part. If solid deposits similar to soot are visible there, then we confidently state: the owner did not observe the maintenance intervals or used low-quality oil.
Then heat the device to operating temperature, dampen and unscrew the lid again. And if blue smoke comes from the neck or the smell of garbage is felt, then the condition of the consumable (and the “dvigla” itself) is disgusting.
In order not to lead to a disastrous overhaul, change the oil not by mileage, but by engine hours. Especially if the engine is supercharged and often pushes the car in city traffic jams. The second piece of advice is to merge mining completely. The AvtoVzglyad portal has already written about this in detail.
Finally, special compositions can also be used, for example the so-called soft engine flushes. They remove various deposits from the system and clean the hydraulic drives. So you can be sure that the lubricant will not fail and the engine will last a long time.
