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
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.

Burn the oil. It is best to use PAO base oil with better performance, better than most fully synthetic engine oils, and burning engine oil does not produce carbon deposits. The fully synthetic motor oil I used before felt pretty average, and I changed to GT Magic Red.
Engine oil, and it lasts a lot longer than the original engine oil, both times are more than 13,000 kilometers to replace, less words to add some, more stable.

If you burn the engine oil, it will be much better to change the quality of the engine oil for maintenance, and my car burned the engine oil at that time and used the magic red engine oil for maintenance, and the phenomenon of burning the engine oil has been well alleviated. The engine oil uses PAO base oil, which is of high quality and much better than mineral engine oil. Moreover, the liquid molybdenum added in the engine oil can well reduce the friction inside the engine, and the fierce driving is also very reassuring, and the protection of the engine is in place.

It's better not to overhaul the engine, many engines are not normally broken, they are repaired. Burn engine oil you have to change the PAO added fully synthetic engine oil to have an effect, PAO wear protection performance is better, I am changing the GT Magic Red engine oil, four types of PAO base oil formula, stable performance, high temperature shear value is also high, so that you can better protect the engine, and the other is GT cleaning additives have a good effect, can remove the sludge and carbon deposits produced by burning engine oil, which can also reduce the burning of engine oil.

When my car burned, the power was really a pool of stagnant water, and the semi-synthetic engine oil was also pumped out later, and the magic red engine oil was replaced with a new one. The power becomes lively, and with a little throttle, the number of revolutions and speed are raised at once. PAO oil also stands out in terms of muteness, and the speed mute of 100-120 is very good.
-
Burn the oil slightly.
In the initial stage, you can choose to increase the viscosity of No. 1 oil.
For example, the viscosity is marked on the back of the oil, and the greater the viscosity at the back.
If you are using 5w20 now, then you can try 5w30. The viscosity is generally W20, W30, W40 can be selected, if you use W40 specifications or burn engine oil, it is recommended to go to the repair shop to consult repair.
-
Burning engine oil is not the problem of the oil itself, but the problem of the vehicle. It is recommended not to use engine oil cheaply, responsible for affecting the service life of the engine.
-
At present, I have not heard of any brand of engine oil that can alleviate the phenomenon of burning engine oil.
If you don't want to repair the engine, you can only add some oil if the light is on before the maintenance time.
-
My car has a slight burn of engine oil, just every maintenance can be left a small half bottle of GT magic red oil, fortunately GT is the base oil of PAO, high quality, and does not produce carbon deposits, just add a little less inspection, burning engine oil is also a common disease of German cars, no way.
Most of Toyota's cars are recommended to add 92 gasoline, and everyone has never heard of any problems with Toyota with 92 gasoline, so it's not just who adds the high mark. >>>More
There are four types of engine oil burning;
1. The EGR valve is damaged, and the oil exhaust gas of the engine enters the combustion chamber, causing the oil to burn. Judgment method: Remove the air intake pipe and check whether there is obvious oil stain near the EGR valve. Solution: Repair or replace the EGR valve. >>>More
Engine oil is by no means a higher grade, the better... The number before w represents low temperature fluidity, so it can be 5w or even 10w in the south all year round... Unless the extreme cold areas in the north are 5w all year round, it is no problem, especially cold places can use 0w, and in summer, you can consider 10w or even 20w... >>>More
In fact, burning engine oil has little to do with engine oil, but if the engine oil is increased, there is a risk of burning engine oil due to excessive wear between engine parts. Secondly, with high-quality engine oil maintenance, there will be less sludge and can also prevent the occurrence of engine oil burning. The original engine oil has been used once, and the second warranty is to change the GT engine oil at the beginning, and the power and silent performance are better. >>>More
Based on the maintenance experience and the characteristics of the model, the reasons for burning engine oil can be roughly summarized as follows: 1. Because the domestic fuel quality is not synchronized with international standards, it is easy to form a large amount of carbon deposits in the combustion chamber during engine driving, and carbon deposits are an important reason for various engine problems such as engine oil burning. 2. Carbon deposits will be deposited in the grooves of the piston, causing the piston rings to stick together, which will cause the piston rings to be stuck and unable to be completely sealed, and the oil will enter the combustion chamber and burn off, while the "sticky" piston rings greatly reduce the ability to scrape oil seals, and the oil that has not been scraped off will also be burned off. >>>More
