Why does BMW burn engine oil with repair agent has no effect, and what kind of engine oil needs to b

Engine repair agents are inherently limited. The best way to increase power and reduce fuel consumption is to change the engine to a fully synthetic engine oil. I also had a burn in Magotan and used the repair agent a few times to feel that the car was immune.

Later, the mineral engine oil was simply changed to GT Magic Red engine oil, and the engine sound was very normal. Then the lubrication of the four types of PAO base oil is very good, and it feels like the engine is wrapped tighter and smoother, full of power, the throttle is lighter, and the shift acceleration power is more powerful and sensitive. The efficiency of the engine has improved, and the fuel consumption has slowly decreased.

Changing the engine oil can not solve the problem of burning engine oil, but only improve the situation of burning engine oil. The original engine oil is of poor quality with mineral oil, and then it will only make the burning of engine oil more serious, if you change the engine oil, you have to change the best fully synthetic engine oil, my friend's X5 used the original engine oil before it was also burned engine oil, fortunately, it was improved by changing the PAO fully synthetic GT engine oil in time, and the power has increased a lot.

Hope it can help you, hope.

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.

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.

The causes of BMW's engine oil burning 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.

Burning engine oil means that the engine oil enters the combustion chamber of the engine and participates in the combustion along 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.

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.

The solution to BMW's burning engine oil is: 1. If the piston ring is stuck by the cylinder carbon deposit, clean the piston ring; 2. If the valve oil seal is damaged, the valve oil seal can be replaced, and it can be replaced without dismantling the cylinder; 3. If the cylinder wall and piston are seriously worn, the engine needs to be overhauled. BMW's models include BMW 1 Series, BMW 3 Series, BMW 5 Series, BMW X1, BMW X3, etc., of which BMW X1 is a compact SUV, equipped with an all-aluminum crankcase and a single-turbocharger four-cylinder engine, this engine can output a maximum power of 245 horsepower and 350 Nm of peak torque, the body length and width are 4454mm, 1798mm, 1545mm, and the wheelbase is 2760mm.

There is no big problem after I burn the engine oil to make up for it in the 5 series, the engine oil is replaced by the original factory with a GT magic red imported raw materials, and I will change it once after running more than 10,000 bridge kilometers, and I will make up the oil once in the middle. The power recovery is very good, the oil quality is high, the oil produces less sludge, the engine is much cleaner, and the high-speed car does not roar. If you use the original engine oil for maintenance, you will not be able to run three or four thousand kilometers if you don't clean the engine before changing the oil every time.
