The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. Burning engine oil is caused by the following factors, as long as the following problems are solved, burning engine oil can be solved.
There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear:
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. In the past, the problem of burning engine oil could only be solved by dismantling and repairing, but now there is a plan to solve the problem of burning engine oil without dismantling and repairing, which can be understood by taking a look.

If the water tank is empty, the high temperature will pull the cylinder and consume the oil.
-
It is inevitable that the oil that plays a lubricating role between the piston and the cylinder wall in the engine will participate in the combustion, as long as it does not exceed one liter within 5,000 kilometers, it is normal oil consumption, and vice versa. The lack of engine oil will cause the engine to heat up badly, the car will shake abnormally, the water temperature will be high, the valve will sound, and in serious cases, it will even strain the cylinder wall or burst the cylinder.
Burning engine oil is basically caused by piston ring stagnation. As long as there is no serious strain on the cylinder wall, it does not need to be overhauled. Changing the maintenance of high-viscosity engine oil is only an expedient measure to treat the symptoms rather than the root cause, and it will do more harm than good.
The solution to burning the oil.
In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.
Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of burning engine oil and having to go to the auto repair shop for overhaul, without removing a screw, repairing and releasing the piston ring stuck engine oil while driving, with remarkable results.

If the car breaks down, call the tow truck to the repair shop to repair it, and driving without oil will cause damage to the large and small tiles in the engine.
-
If the oil lamp is still on after the car is on fire, it may be a lack of oil, check the oil dipstick to see if there is less oil, and if it is less, add it at the same time to see if the engine has oil leakage or oil leakage or whether the car itself has begun to burn oil; If there is a lot of oil, then check whether the oil induction plug is broken, and finally whether the oil you add is ** (some fake oil viscosity is not up to standard, although the oil is not lacking, but the oil lamp will also alarm).
-
Check and replace the cylinder gasket, it may be that the cylinder gasket is bad.
-
In this case, you can go to a professional to consult to see what to do, or go to the maintenance point to find a maintenance person to help you repair and repair, do not deal with it privately, so as not to cause losses.

Burning engine oil is blue smoke, how much is burned? The engine oil is not anti-wear, try to change the oil;
Oh, I know that Audi cars and BMW cars burn engine oil because the oil is not anti-wear, some car owners have used super American eutectic engine oil, do not disassemble the engine, solve the problem of not burning engine oil, large truck excavators use super American eutectic does not burn engine oil.

JAC is a well-known brand in China, but it does not mean that the vehicle will not burn engine oil, how to solve and judge? If the vehicle is too old and the exhaust emits blue gas, it means that it is already very serious and the protective agent has no effect, and you must go to the 4S shop to replace it.
"Burning engine oil" will cause damage to the vehicle's oxygen sensor too quickly, resulting in an increase in carbon deposits in the combustion chamber, unstable idling, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences, resulting in insufficient engine lubrication, which will cause the engine to cause irreparable damage or even accident hazards in the long run, resulting in a significant increase in maintenance costs and even scrapping.
In the early days, you can use the BOD's magic pressure to protect the engine, and its role is to be.
It can reduce friction, extend engine life, and run the engine more smoothly.
Reduces fuel consumption and engine piston ring leakage.
Keep the oil seal and cushion soft.
Elimination"Cold start"problems, quickly restore horsepower.
Eliminates long-term accumulation of engine gels and oil film deposits.
Improve the cylinder compression ratio and inlet vacuum suction.
How to use: 1) Start the engine, idle it until it reaches normal temperature, and turn off the engine;
2) Drain the oil in the crankcase; (It is best to change the oil grid and filter it with new oil again to avoid the residue of old oil).
3) Add 2 litres of new oil to the crankcase;
4) Add 1 bottle of BOD Magic Pressure Engine Protector to the crankcase; (Half a bottle can be added to the new car).
5) Continue to add some new engine oil to the crankcase (slightly less than 2 liters, pay attention to the oil dipstick scale);
6) Close the crankcase cover, close the engine cover, start the car, idle for 15 minutes or drive 20 km.
This is some of my practical experience, and at the same time, it can also solve the problem of burning engine oil, which is not necessarily the best, but it is actually used.

Hey, the current special engine oil is not good, it is not as good as the outside engine oil, you can choose the brand. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, if the engine burns oil, you have to go to the repair shop to check it, and you generally need to check the valve oil seal and the piston ring of the engine.

Hello, if it's a slight burn of engine oil don't worry about him,

Overhaul of engine oil is not the only way to solve the problem, as long as the cylinder wall is not worn out much, and the cylinder pressure value is normal, it does not need to be overhauled. Other related parts that will cause oil consumption, such as wastegas valves, valve seals, turbines, etc., should be replaced directly if they are damaged, even if they are overhauled.
Engine oil piston ring stagnation is a common problem, even if the engine is dismantled and overhauled, the possibility of re-burning is also very large, and the overhaul is not only costly, the risk of depreciation can not be ignored. Even if the replacement of high-viscosity engine oil is relieved, it is only a measure of equity, and the root cause of the problem is still there, and if it is not completely solved, it will lead to serious strain of the engine wall or even cylinder bursting, resulting in irreparable losses.
In fact, it is very simple to solve the piston ring stuck engine oil, you can choose to use PNF non-destructive repair technology to clean and release the piston ring in the oil and fuel synchronously, and solve the problem of burning engine oil while driving.

Let's see if it's normal wear and tear to burn engine oil? I don't know if you are often short of oil or if there is blue smoke coming out of the exhaust pipe! Sometimes it is the oil in the waste pipe that is strung into the intake pipe, and then it causes the engine oil to burn, so you should first go to the rest plant to overhaul it and see the reason for the oil burning.
If you don't want to overhaul, if the cylinder barrel and crankshaft are not worn out after disassembly, you can do a three-guarantee. Changing the piston rings and valve seals will do the trick. It can be done in a day.

There are four common reasons for burning engine oil.
1.If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, detergents are used at will, and using detergents and effective detergents are two different things;
2.The antifreeze replacement cycle is too long or not changed at all;
3.The oil change interval is too long;
4.Long-term or often short-distance driving.
The above four points of the vehicle that burns engine oil must be occupied by one or three points.
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
Carbon deposition is indispensable in the combustion process, and carbon deposition is the root cause of some automobile failures, such as the aging of valve seals, piston wall clearance, etc., which are directly or indirectly related to the formation of carbon deposition, so keeping the fuel oil circuit clean is of great help to prevent burning engine oil, of course, this needs to be done with the help of high-quality fuel additives.
3. With the help of external forces
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 solving the problem of burning engine oil without dismantling and repair.

Causes of burning engine oil:
1. Burning engine oil in a cold car: When the temperature of the car is not completely warmed up, the engine exhaust pipe emits a lot of blue smoke, but it is normal after the car is heated. This phenomenon is caused by the aging of the valve oil seal.
Due to the decrease in temperature, the valve oil seal of the rubber material is stiff and cannot be completely sealed, and the oil leaks from the valve into the combustion chamber and burns.
Solution: Remove the engine cylinder head and replace the valve oil seal (please rest assured, this belongs to the repair project.) The repair time is about 4-5 hours. The cost ranges from 800 yuan to 1200 yuan, depending on your car).
2. Hot car burns engine oil: After the car reaches the normal temperature, the exhaust pipe still emits blue smoke, which indicates that the piston ring has a poor seal. Due to the poor sealing of the piston ring, the oil directly enters the combustion chamber through the piston ring leakage under the action of the oil pump, and there is a phenomenon of blue smoke from the exhaust pipe.
There are several reasons for this phenomenon, such as: material aging, carbon deposition jamming, excessive wear of cylinder liners, etc.
Solution: According to the normal operation method, the engine needs to be lifted down for overhaul operations. The repair time is about 2-4 days. The cost ranges from 5,000 yuan to 20,000 yuan, which needs to be combined with your car, and the cost is mainly high in accessories.
In addition, there is another way to deal with it: if it is determined that the oil is burning in a hot car and it is not very serious (for safety reasons, the cylinder pressure test can be carried out first), the oil pan can also be removed directly, the piston can be directly taken out, and the piston ring can be replaced, so that the cost and time are similar to the first solution.

At the beginning, a little oil was burned, and the new assembly of the plug ring cylinder surface was completely fitted between the run-in sections; Serious oil burning should be assembled with plug ring mouth or twisted ring installation to burn engine oil.
The water temperature is high, eliminate the problem of thermostat, first poke the water tank (estimated that the water tank is blocked), and the bearings of the just repaired machine are tighter, and the friction resistance of the cylinder wall is tightened, and the cylinder pressure increases to create a temperature increase, and the run-in section is increased.
No, the car water tank is out of water and continues to drive, which can seriously cause the engine to be scrapped.
