Yes, the engine oil itself is consumed to a certain extent, 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 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.

Generally, it has to be dismantled and repaired.
If the vehicle with a relatively long number of kilometers burns engine oil seriously, the most direct reason is:
1. The engine valve oil seal is aging and damaged, and the oil participates in combustion through the valve to the combustion chamber or adsorbs on the valve carbon deposit.
2. The engine piston ring is aging or stuck, causing the oil to enter the combustion chamber; The most straightforward and thorough way to deal with this situation is to overhaul the engine and replace the piston rings and valve seals. If the engine repair agent is added, select qualified fuel or change the oil label, clean up the engine carbon deposit, etc. It can slow down the phenomenon of burning engine oil, but not completely**.
In the case of a vehicle with a short mileage or under warranty, the chances of failure of the piston rings and valve seals are generally slightly smaller. When you find a problem, you must go to the 4S store in time to check and deal with it.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Automobile oil burning is mainly caused by the following reasons:
1. a valve oil seal; 2. The piston gap is too large; 3. Driving habits; 4. The amount of engine oil is too much.
"Burning oil" means that the oil enters the combustion chamber of the engine and participates in the combustion together with the mixture. The phenomenon of "burning engine oil" in the vehicle will damage the vehicle's oxygen sensor too quickly, resulting in an increase in carbon deposition in the combustion chamber, unstable idling, weak acceleration, increased fuel consumption, and excessive exhaust emissions.
Symptoms of burning engine oil.
1.Check whether there is blue smoke from the exhaust emissions; 2.Check if there is a frequent lack of oil (except for oil leaks); 3.
Check that the car is difficult to start cold 4Whether the power of the car decreases (the power decreases after the compression ratio decreases) and other steps can determine whether the engine oil is burned. 5.
The engine is noisy, check for idle jitter. Use the company to dismantle and repair the burned engine oil and restore normal oil loss.
Solution. 1.Remember not to overhaul the engine oil, overhaul and dismantle the engine will bring infinite unpredictable risks, disassembling the engine at room temperature will lead to a serious decline in the sealing performance of the engine, and soon the engine will lead to greater problems.
2.If you find that the symptoms of burning engine oil are good at repair. You can use zero dismantling non-destructive burning oil repair agent, the problem of piston ring can be completely solved, after the release of piston ring, the oil scraping function is normal, there will be no more such serious phenomenon of burning engine oil caused by piston ring stagnation.
At the same time, the oil circuit of the car, the carbon deposit, the carbon deposit on the piston top, and the fuel injector can be dredged and cleaned. At the same time, it is recommended to check whether the exhaust valve is seriously aged before repairing, if so, it is recommended to replace the exhaust valve first, and then repair the engine oil. In this way, detours are avoided and waste in the repair process due to oil consumption due to the aging of the wastegate.
In fact, even if the exhaust valve is not replaced, it can also play a good role in maintaining the car while cleaning the oil circuit and carbon deposits, as well as releasing the piston ring.

1.You can not avoid dismantling and repairing, and the car "burns engine oil."
It will damage the vehicle's oxygen sensor too quickly, resulting in increased carbon deposits in the combustion chamber and idling.
Unstable instability, weak acceleration, rising fuel consumption, excessive exhaust emissions and other adverse consequences, resulting in insufficient engine lubrication, long-term will cause irreparable damage and even accident hazards to the engine.
As a result, the cost of maintenance has risen significantly and even been scrapped.
2.In the early days, the BOD can be used to protect the engine, which can reduce friction, extend the life of the engine, and make the engine run 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.
Increase the cylinder compression ratio.
and inlet vacuum suction.
You can try these usages:
1. Start the engine, idle it until it reaches normal temperature, and turn off the engine;
2. Put 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 liters 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. Cover the crankcase cover, close the engine cover, start the car, and idle for 15 minutes or drive 20 kilometers. 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.
Most of the Accord burning engine oil is caused by the piston ring being trapped by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. The poor power of the engine is due to the fact that the oil participates in the combustion and forms more carbon deposits, which in turn aggravate the degree of oil burning and form a vicious circle. >>>More

In general, no, there are special circumstances.
Hello! If you can't catch fire, you check it out.
1. Check the valve clearance, if it is not right, you need to adjust it, if your car is DHOC, you have some annoyance. Valve gaskets are not easy to find. >>>More
Open the front hood, there is a yellow pull ring on the side of the engine, that is the oil dipstick, you can pull out, the bottom is the upper and lower limit of the scale, wipe dry and insert it in the pull out to see, between the upper and lower limit is OK. >>>More
