Ford Mondeo 2, ot 80,000 kilometers to burn engine oil

Most of the Ford Mondeo engine oil burning is caused by the piston rings 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 and high fuel consumption of the engine are 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.

Too much carbon deposits will clog the fuel injector, resulting in poor atomization and poor combustion. In the long run, it will cause cylinder wall strain, or even cylinder burst, and finally the engine can only be disassembled for overhaul.

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 the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.

There are still a lot of turbocharged cars that burn engine oil.

The reasons why cars burn engine oil can be understood first:

Domestic oil products and road conditions are prone to carbon deposits (there is no way to change this, only fuel additives can be used to improve oil products).

Carbon deposits cause the piston rings to jam and lose their oil wiping properties.

Wear between the cylinder wall and the piston, the gap is too large.

The corrosion and aging of valve oil seals and crankshaft oil seals cause oil leakage.

This is just a few core reasons, car oil burning is a very complex problem, there are many reasons, burning engine oil is not formed in a day or two, and it will not be solved in a day or two. To solve the problem of burning engine oil, you can use the method of non-disassembly, because dismantling and repair is very harmful to the engine and is not recommended. The method of no dismantling and repair is to use a set of products from German Marty, first of all, clean the carbon deposits, including the engine and oil circuit system, and then repair and protect the engine, avoid rough and sharp friction, and make the corrosion and aging oil seal expand again to restore elasticity.

There are many benefits of this, while solving the problem of burning engine oil, the power of the car will be greatly improved, the fuel consumption will be saved by more than 10%, and the exhaust gas is not up to standard.

The reasons for burning engine oil are:

Worn valves and ducts, damaged oil seals;

The cylinder, piston and piston ring wear exceed the limit;

Air booster leakage.

The above faults can be solved by repair.

Because their technology and oil can't solve it.

In fact, the engine oil is not anti-wear, so there will be so many things about burning engine oil, and there is no original engine oil at all, and there is no special engine oil, which has long been clarified. If you want to prevent burning engine oil, no matter what Mobil Shell Castrol is used, you can't do it. Because the engine oil is not anti-wear, even if it goes to the overhaul shop, the oil will be burned after repair...

It is best to use anti-wear repair super eutectic engine oil, after two times, it will return to the power of the new car, many BMW Audi Benz have been used, and the effect is good.

Just after the overhaul of the engine, the cylinder pressure is not low, and the cylinder head is particularly oil-burned.

Hello, there are several reasons why the engine burns oil. 1. The piston ring is stuck with too much carbon deposit, the 2-valve oil seal is aging, and the 3-piston and cylinder wall are worn, resulting in too large a gap and a loose seal. This one requires an overhaul of the engine.

If the Ford Mondeo is not used properly, it will burn the engine oil, and the oil itself has a certain consumption, which is normal. If the consumption is too large, there is a problem of burning oil. There are the following factors in burning oil, as long as the following problems are solved.

1.Use oils that are of poor quality or do not meet the requirements of the viscosity grade. Low bench dust and oil quality will lead to increased wear.

In addition, too low or too high oil viscosity can lead to poor engine lubrication, which can increase wear on piston rings and cylinder walls, reduce sealing performance, and lead to oil burning. 2.The gap between the piston ring and the cylinder wall is too large, the piston ring is improperly installed or the sealing performance becomes poor, and the oil on the cylinder wall enters the combustion chamber, resulting in oil combustion; In addition, poor sealing performance of the valve seal, damage to the crankcase forced draft valve (PCV) or clogged crankcase vent can cause excessive pressure in the crankcase and cause the oil to enter the cylinder with the crankcase gas and participate in combustion.

4.Turbocharger oil leak. The turbocharger is mounted at the front of the exhaust pipe and operates at a high temperature.

When the engine is running at full load, the speed of the turbine and pump wheel can reach 10,000-20,000 rpm. The turbine shaft has oil-lubricated floating bearings and an oil passage to the turbocharger. Or an oil leak from a pipe or bearing can cause oil to seep from the turbocharger into the exhaust pipe.

When the exhaust pipe temperature is high, the oil is roasted into blue smoke and discharged. 5.The valve oil seal has a leak, which means that the oil leaks through the valve oil seal into the combustion chamber and burns.

Ford Mondeo will burn engine oil if it is not used properly, and the engine oil itself has a certain consumption, which is normal. If you consume too much, there is a 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.

1. Use engine oil with poor quality or viscosity grade that does not meet the requirements. In addition, too low or too high oil viscosity can lead to poor engine lubrication, increased wear of piston rings and cylinder walls, and reduced sealing performance, resulting in oil burning. 2. The matching gap between the piston ring 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 the engine oil; In addition, poor sealing performance of the valve seal, damage to the crankcase forced draft valve (PCV) or crankcase vent blockage can cause excessive pressure in the crankcase to cause the oil to enter the cylinder with the crankcase gas and participate in combustion.

3. Burning engine oil caused by excessive oil filling. When the oil is filled above the center line, the part of the engine lubrication process that passes through splash lubrication will be too much into the combustion chamber due to the high oil pressure. 4. Oil leakage from turbocharger.

The turbocharger is installed at the front of the exhaust pipe, the operating temperature is very high, and the turbine and pump wheels can reach 1-20,000 revolutions per minute when the engine is running at full load. The turbine shaft has oil-lubricated floating bearings, and the car has one oil passage to the turbocharger. Oil leaks from pipes or bearings can allow oil to seep from the turbocharger into the exhaust pipe.

When the exhaust pipe temperature is high, the oil is baked and discharged into blue smoke. 5. There is leakage in the valve oil seal, which means that the oil leaks into the combustion chamber through the valve oil seal.
