What is the difference between "losing oil" and "burning oil"?

About losing oil and burning oil, there are always friends confused, thinking that he is just two names, in fact, it is the same thing.

Master Bang told everyone that this is a completely different matter; So today, we will talk about what is "lose oil", what is "burn oil".

Discard Oil

First of all, we first talk about what is "lost oil", lost oil generally refers to oil leakage, is a relatively serious phenomenon.

Oil leak

There are many reasons for the phenomenon of oil loss, the more common such as may be the engine seal is damaged, or the oil seal is damaged, resulting in failure to seal, oil leakage in the flow process, it may also be loose screws, piston ring opening gap is too large and other reasons.

To check whether the oil has been lost, the method is very simple, see whether the engine guard plate has a lot of oil, you can also stop the vehicle for 12 to 24 hours, see whether there is oil on the ground.

If the oil leak is found, it is recommended to directly send the car to the 4S shop or repair shop to check the reason, and then see how to deal with it.

Burning oil

Losing oil is oil leakage, burning oil is oil consumption.

Oil consumption

In fact, most vehicles will have oil burning, but the degree is relatively light, and it is normal. The burning oil we are talking about now is that excessive oil enters the cylinder and participates in the combustion with the mixed gas, resulting in a large amount of oil consumption.

In general, the oil does not enter the combustion chamber in the following circumstances:

01

Valve oil seal

Valve oil seal is an important part to prevent oil leakage into the combustion chamber, but with the increase of the age of the car, valve oil seal wear, aging and other situations, it will affect the sealing of the valve, so that the oil is easy to leak into the combustion chamber when the engine is running, and the phenomenon of burning oil.

02

The piston ring gap is too large

Older models often have insufficient combustion carbon deposits adhering to the piston ring, if not cleaned up for a long time, it is likely to expand the gap between the piston ring and the cylinder, resulting in oil flow into the combustion chamber, resulting in the phenomenon of burning oil, and even lead to the engine "cylinder explosion" phenomenon. Therefore, it is very important to regularly clean the carbon deposit of the engine, and it is also an effective way to prevent burning oil.

03

overoil

If the amount of oil added exceeds the normal demand for the engine, the engine pressure is too high, and the excess oil will enter the combustion chamber.

Once the car burns oil, its harm is also very great.

First of all, since the oil consumption, then the first harm is the cost of money, for about one thousand two thousand kilometers of burning a liter of car, a year at least an additional consumption of about 1500 yuan of oil money.

Secondly, excessive oil entering the combustion chamber may lead to a rapid increase in carbon deposition in the combustion chamber, increasing the resistance of oil flow. When you usually drive, you are still in place when you step on the accelerator, and the small electric donkey next to you has gone out far away, and the power is obviously insufficient. In addition, due to the increased resistance, you will find that before only 9 oil 100 kilometers, now become 11 oil 100 kilometers.

If it is serious, the carbon accumulation caused by burning oil can easily lead to the piston ring sticking, and may also lead to accelerated wear of the piston and cylinder wall, resulting in a lax piston seal, which fofows the next step of burning oil and falls into a vicious cycle. There will even be cylinder pulling, engine scrap and other results.

Having said so much, how to judge whether to burn oil? We can see if there is blue smoke coming out of the exhaust pipe when we start cold in the morning, when the vehicle is driving or when we step on the accelerator in place. If we find that there is, it is necessary to consider burning oil. At this time, go to the repair shop as soon as possible to repair the car, so as not to wear the engine.
