How to tell if the engine oil is consumed normally or the engine oil is burned

Consumption or burn oil how to judge the burning of engine oil First of all, the oil added to the vehicle will be more or less consumed, but it is obviously not an obvious problem, generally speaking, it is normal to consume 1 liter of engine oil every 5000 kilometers, and it is necessary to pay attention to it if it exceeds this standard to see if the following situations occur. The exhaust pipe is very dark First wipe the inner wall of the exhaust pipe clean, and wipe it again after a week, if you find that the exhaust pipe is very black, it means that the vehicle has the phenomenon of burning engine oil. Blue smoke when the cold car starts in the morning Pay attention to the exhaust pipe outlet when the cold car starts in the morning, if the exhaust pipe emits blue smoke when it is just started, it means that the vehicle burns the engine oil, this method is best completed by two people, one person starts the vehicle, and the other person is responsible for observing.

This is because the blue smoke emits for a short period of time and only appears after the vehicle has been left for a long time. Blue smoke when the throttle is large When the vehicle accelerates sharply or hits the throttle in situ, there is a phenomenon of blue smoke, and there is basically no when idling, which means that the vehicle burns oil, and it is more serious, and it should be repaired as soon as possible. Blue smoke from the oil inlet If the oil inlet of the vehicle starts to emit blue smoke in addition to the exhaust port, it means that this symptom has reached the middle and advanced stages, and the burning of engine oil is very serious, and you need to seek medical attention as soon as possible to avoid causing greater damage.

The poor sealing of the cylinder is the main cause of oil burning. The main reason is that the matching gap between the piston and the cylinder wall is too large, the piston ring is improperly installed or the sealing is poor, and the oil on the cylinder wall enters the combustion chamber, causing the phenomenon of burning oil. Choose good quality engine oil as much as possible, old vehicles can appropriately choose slightly more viscous engine oil to increase the sealing between the piston and cylinder wall, use mineral engine oil for a long time, and change to fully synthetic engine oil is also prone to poor sealing.

Checking the oil ruler frequently, regularly changing the oil and oil filter, replacing the spare parts of the oil filter, and choosing the original engine oil can effectively avoid the phenomenon of burning engine oil.

Causes of burning engine oil and how to prevent it.

The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the following reasons will aggravate the oil consumption and cause the burning of engine oil, so that the vehicle appears:

1. Carbon deposition occurs in the combustion chamber, which makes the gas ring of the piston ring stuck, and the sealing is poor.

2. Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance.

3. Wear occurs between the piston and the cylinder wall.

4. The valve seal is corroded and aging, and the sealing performance fails.

In addition, cars now have crankcase ventilation systems (exhaust valves), which can also exacerbate oil consumption if there is a problem.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel in the combustion process is indispensable to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all have a direct or indirect relationship with the formation of carbon deposits, considering the relationship between domestic oil products, it is necessary to use high-quality engine oil and (PNF) fuel additives to achieve, which is also the key to achieve no dismantling and repair to solve the problem of burning engine oil.

1. When the car is first started in the morning, the exhaust pipe appears a thick blue smoke, and the blue smoke disappears after a while, and this situation may not occur again on the same day, but this phenomenon occurs again on the second and third mornings, which indicates that the vehicle has burned engine oil, which is called burning engine oil in a cool car.

2. When the vehicle is driving or on the spot, the exhaust pipe emits a large amount of blue smoke when the driver slams on the accelerator, which indicates that the phenomenon of the vehicle burning engine oil has been more serious, which is called accelerating the burning of engine oil.

3. In addition to the blue smoke coming out of the exhaust pipe, you can also see pulsating blue smoke coming out of the oil port of the processor. In this case, the damage to the engine is already severe.

Burn the oil"This is when the oil enters the combustion chamber of the engine and participates in the combustion along with the gas mixture. Vehicles appear"Burn the oil"The phenomenon will cause the vehicle oxygen sensor to be damaged too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences. In the traffic conditions of frequent starts and stops, many car owners reflect that they love their cars"Burn the oil"Then, it is necessary to understand the hazards, identification and avoidance methods of burning engine oil.

Maintenance method: 1. The habit of regular inspection of the car, daily maintenance is a must, and we must check the corresponding frequency according to the mileage of the vehicle and the driving environment, so as to "prevent problems before they occur".

2. Use better quality engine oil, and the stability of high-quality engine oil is also relatively good, which can maintain appropriate viscosity at high temperature and high speed of the engine and reduce oil consumption. Moreover, the oil should be added in accordance with the norms, not too little, not too much. Burn the oil

3. Regular maintenance and replacement of engine oil or oil filtration. In general, the maintenance interval is 5000 km.

Hello: Under normal circumstances, the color of the engine oil exhaust pipe is blue, and the oil consumption is abnormal. The normal oil consumption of the engine is generally not more than normal per 1,000 km.

I hope it can help you, if you have any questions, please log in to Baichebao Q&A to find me, I will answer for you.

Not all oil consumption is burned oil, because the engine itself cannot fundamentally eliminate oil consumption. It is understood that the current standard of German car manufacturers is the consumption of oil liters per 1,000 kilometers, and the corresponding standard in this area is also proposed in China, which is the consumption of oil liters per 1,000 kilometers, and the oil loss below this consumption is the normal consumption of the vehicle in the process of use. If the oil burns does occur, it is recommended to try this oil.

The oil consumption of the car, that must have gone into the cylinder and burned out.

Theoretically speaking, within a maintenance cycle, the engine oil will not be lower than the lower limit of the oil dipstick, which is not a serious burn of the stove oil. The hidden performance of burning engine oil: 1. When the cold car starts, a very thick blue smoke is produced at the exhaust pipe and disappears after a period of time.

2. When the vehicle slams on the accelerator or slams on the accelerator on the spot, a large amount of blue smoke is discharged from the exhaust pipe, and it can even be seen from the rearview mirror in serious cases. 3、

<> "How to judge burning engine oil?

Burning engine oil is now a familiar word, which means that the engine oil enters the empty combustion chamber of the engine and participates in the combustion together with the mixture.

However, not all oil loss is to burn engine oil, because the internal parts of the engine have a certain gap, so normally the oil itself will also be consumed, but generally as long as every 5000 kilometers consume less than 1L of engine oil is a normal situation, and it is not considered to burn engine oil, there is no need to worry at all, as long as the oil volume is checked regularly to ensure that there is no loss of oil.

However, if the engine oil is really burned severely, it will be easy to produce carbon deposits, resulting in fuel consumption, engine shaking, weakened power and excessive emissions, and it will also cause oxygen sensor failure, cause blockage of the three-way catalytic converter, and lead to three-way catalytic damage in the long term.

And if the vehicle does not have an oil pressure alarm, because the oil itself is not easy to attract our attention, once the oil loss is serious, the engine lubrication is insufficient, it is likely to lead to engine cylinders, crankshaft damage and other very serious problems.

So how can you tell if the vehicle is burning engine oil?

The most accurate way is definitely every other kilometer, such as every 1000 kilometers (according to the vehicle) to observe the oil dipstick, if there is obvious oil consumption then there is a high probability that the oil is burned, if not, you can extend the observation period.

Although the above method is the most accurate and effective, if you want to buy a used car, it will not work.

If the oil is burned slightly, it is difficult to see it directly through the naked eye in a short time, but fortunately, the slight burning of engine oil does not cause much damage to the engine, as long as the oil is replenished regularly.

Although heavy burning of engine oil is very harmful, it is relatively easy to see through the naked eye in a short period of time.

1.Blue smoke from the cold-start exhaust.

After the vehicle is parked for a period of time, due to the action of gravity, the oil will flow into the cylinder through the gap of the valve oil seal, and then start the engine, if a large amount of blue smoke is generated, it means that the oil flows into the cylinder too much, and the valve clearance is abnormal and causes the oil to be burned.

2.Big throttle exhaust emits blue smoke.

If the gap between the piston ring and the cylinder wall is too large, the remaining lubricating oil on the cylinder wall will be carried into the combustion chamber by the piston ring, resulting in oil burning.

Of course, although the burning of engine oil is not necessarily a problem with the valve oil seal or piston ring, it may also be caused by other problems, but at least if there is blue smoke from the flushing pipe of the mold exhaustion, it must be the burning of engine oil. So if you're looking for a second-hand car, it's a good idea to see if the exhaust of the vehicle emits blue smoke during cold starts and high throttle if possible, and if so, leave as soon as possible.

Hello! Generally from two aspects,1Exhaust seepage refers to blue smoke emitting from the suspected pipe; 2.The engine does not leak oil, and the oil is constantly decreasing. Xi Cong's hand hope tease failed to help you, thank you!
