The manufacturers provide for the consumption rates of engine oil for engines of various types. This is due to the very design and operation of the internal combustion engine. However, if the engine starts to "eat" oil, this serves as a signal for repair work. Of great importance in oil consumption depends on its quality and properties such as viscosity.
Any engine consumes engine oil during operation. The consumption rate depends on the characteristics of a particular internal combustion engine mask, its volume and operation. On average, oil consumption can reach two liters per 1000 km. In a serviceable internal combustion engine, the consumption of lubricating fluid remains uniform under various operating modes. New generations of cars operating in accordance with Euro-5 standards have longer intervals between maintenance, since the oil must be constantly added.
The use of fuels with a low sulfur content increases the life of the engine oil, prevents aging and, accordingly, increased consumption. The degree of "eating" of oil by the engine can be derived from the engine volume and the consumption of the fuel mixture. For ordinary cars with a gasoline atmospheric internal combustion engine, the norm is 10 - 25 grams. for 100 liters. gasoline. V-shaped motors with six or more cylinders can consume up to 50 grams. With severe engine wear, the consumption rises sharply and can reach 600 g. and more for 1000 km.
If we talk about turbocharged engines, they require within 800 grams. until the next change. The critical level in this case is two liters per 100 liters. gasoline. If we talk about a diesel engine, then oil is consumed here less, about half a liter per 10,000 km.
These standards do not apply to all internal combustion engines. There are motors for which the critical oil consumption of other engines enters normal operation. Special attention should be paid to ensure that the ignition is adjusted correctly. Early or late fuel injection drastically decreases engine efficiency.
Features of oil consumption in modern internal combustion engines
Now power automotive units achieve high levels of environmental friendliness, maximum lightness of the body and, at the same time, significant power. This is one of the main reasons for wasting oil. He has to be at high pressure and sudden changes in temperature.
Most of the reasons for "eating" oil lies in the elementary failure of the gasket or wear of engine parts. And before you scold the designers and manufacturers of the engine, you should make sure that it is working properly. The highest probability of wear is in the parts experiencing maximum friction, even in comfortable working conditions.
Why does the car "eat" oil?
If you do not take the design features, the type and power of the engine, then there are many more reasons for the increased oil consumption:
· Unsuitable lubricant for the motor;
· Valve gaskets are worn out, even if only slightly;
· The ventilation is faulty and the gases are compressed in the crankcase;
· Oil-repellent caps are worn out;
· The piston rings (oil scraper) have become unusable;
· Damaged cylinder bodies;
· Faulty cylinder head gasket;
· Oil seals of the crankshaft or camshaft do not work (both sets of oil seals may be out of order);
· Failure of the oil filter.
Before filling with crankcase oil, you should study the documentation of the ICE manufacturer, there are usually several viscosity options indicated. If more lubricant is supplied, then it simply burns along with the fuel mixture and goes out simultaneously with the exhaust gases into the pipe. Correct running-in of the machine is important.
