If the car constantly fills with spark plugs, there are ignition problems, it means that the oil is not filled in the engine according to the level. First, fuel consumption increases, then power begins to fall before our eyes. To understand the topic, you need to first look at the underfill and then the overflow situation.

What happens if the oil level is lower than normal

If the machine shows lower than normal oil, it means that the engine is running without lubricant. It is generally accepted that nothing bad happens.

Many drivers visit exhibitions and local exhibitions work without lubrication. You can see how the oil is not poured at all and the unit continues to work hard.

Actual machine operating conditions:

  • high engine speeds;
  • considerable temperatures;
  • infrequent inspections and polishing.

In real combat conditions, the engine does not idle most of the time. This means that oil is needed in large quantities. In particular, the esters which deposit on the walls of the engine are important.

At high temperatures, metal does not always withstand loads. Hydrocracking avoids the destruction of the parts, they do not melt.

Reasons for shortage:

  • waste of material;
  • the presence of clots from the previous oil;
  • thin film on the walls.

Some engine oil is constantly wasted. Synthetics quickly clog the chamber and stay there for some time. If you do not check the oil level for a long time, there will certainly be problems with the sealing.

Consequences of fasting:

  • wear of crankshaft bearings;
  • crankshaft journal friction;
  • wipe down the liners.

Engine oil mixtures and, when in short supply, do not help the bearings in any way. Residual components not only protect the crankshaft, but also the liners.

Additional effects of fasting:

  • crack blocking;
  • increased load on the power unit;
  • temperature increase.

High molecular weight petroleum hydrocarbons prevent clogging of cracks. Polyalphaolefins, in turn, reduce the load on the engine. Active components are not afraid of high temperatures, so the motor runs for a long time.

What happens if the oil level is too high

Some are curious how too much oil affects the car. Maybe additives would work better. Drivers also experiment with ash content.

It seems to some that clear oil can be filled to the brim. However, they do not take into account the level of pollution. Even with 100% filtration, small particles settle on the motor surface and stick.

Ignore the consequences:

  • foaming liquid;
  • air bubbles in hydraulic compressors;
  • gear wear.

Large amounts of additives adversely affect engine operation. At first they retain the mobility of the elements, but deposits appear over time. By themselves, they are not dangerous, however, during engine tests, it was proven that the material does not evaporate.

In other words, the deposits accumulate and clog the filter. In this case, even strong solvents do not save. Some try to clean, but fall on the detergent. It is an astringent additive that is used in a wide variety of engine oils.

Mineral oils are considered dispersant oils. In other words, they are erased and seem safe. However, there is no escape from the antagonistic effect. The more additives the driver adds, the faster the engine develops a resource.

The consequences of a shortage and a collapse are described above. In the first and second cases, interesting consequences are observed. The driver needs to restore the vehicle for a long time in order to enjoy quality driving on the roads again.
