How much does it cost to deal with the oil burned in the Jindian Fox engine

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.

Most of the Ford Focus 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.

It's really troublesome to encounter this, the car itself may have defects, to be honest, you have more than 2 years of car running too little, but also one of the factors that caused this failure, you said that you did the fourth free maintenance in March 08, 06 years to buy a car, a total of 4 times in 2 years to change the oil, the oil in the car for a long time is not good for the machine, the oil itself deteriorates, the consistency changes, it is recommended that you run more cars, if you really do not run much, it is recommended that the oil is changed at most 4-5 months.

The Focus is not a turbocharged car, so it is impossible to burn oil. Only Volkswagen and Audi cars burn engine oil.

I just heard that there is an oil leak in the new Focus, but I haven't heard of burning engine oil.

The Focus is not a turbocharged head and it is impossible to burn oil.

First of all, it is necessary to be clear about what burning engine oil is.

Burning engine oil refers to Volkswagen's cast iron head, which raises the temperature of the head sharply under turbocharging in order to increase the power.

The temperature is so high that the oil volatilizes It's not that the oil is burned as gasoline, so the Focus won't burn the oil, it can't burn if it wants to, it's not that high, but his 6-speed dual-clutch transmission is a big oil leaker... The whole country knows it.

The reasons for burning engine oil in Classic Focus: using engine oil with poor quality or viscosity grade that does not meet the requirements; There is a leak in the valve seal. This is mainly due to problems with the oil used and the valve seals.

It can even cause problems with the car's engine, because the main function of engine oil is to lubricate the engine.

What to do if the classic Focus burns engine oil to go to the repair shop for maintenance, there are several situations of general oil burning:

1. The oil leaks into the cylinder from the valve, which is generally caused by the loose sealing of the valve oil seal. The solution is to replace the valve seal, and if the valve guide is severely worn, replace the valve guide or even replace the valve.

2. Caused by leakage of cylinder piston rings. For example, the oil ring scraping capacity is reduced, or the air ring leaks, resulting in too high pressure in the crankcase, and the large airflow through the crankcase ventilation brings too much oil mist into the intake pipe. Causes oil to burn.

In the case of this case, the ring can be replaced, and in the severe case, only the piston group (including the piston ring) boring cylinder can be replaced. It's an overhaul. You can check the cylinder pressure first, if it is normal, the problem is not big, just change the valve oil seal.
