What should I do if the old Suteng burns the engine oil after 150,000 kilometers

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.

If it is an old vehicle that burns engine oil, you can appropriately choose to add a relatively large viscosity oil to the engine to increase the sealing between the engine piston and cylinder wall, and the ultimate way to completely solve the problem of burning engine oil is to overhaul the vehicle more thoroughly, so as to fundamentally solve the problem.

Self-priming engines do not require much oil performance and can be used with mineral oils as well as semi-synthetic oils, and if the consumer economy allows, fully synthetic oils can be used. Compared with the self-priming type, the turbocharged engine has more precise internal engines, more demanding working conditions, higher requirements for oil quality, and requires oil with better fluidity, and it is best to use fully synthetic engine oil.

For the choice of motor oil brand, focusing on the long-term life of the engine oil, Mobil oil can be selected; If you need engine oil with strong cleaning ability, it is recommended to choose Shell engine oil; For lubricants that require strong film toughness, Castrol is recommended. Turbocharged engines, for example, are prone to carbon build-up at high speeds, so choose Shell fully synthetic motor oils with strong cleaning properties.

The steps of Suteng to change the engine oil first park the car on the trench construction platform, turn off the fire switch, turn off the engine, tighten the hand brake, put the car on the front and back of the four wheels, cover the wheels with a triangle wood, etc., and then, open the cover of the chain, open the oil filling hole, pull out the oil dipstick for later use, put the waste oil equipment on the bottom of the oil drain plug at the bottom of the large oil bottom, twist the oil plug with a wrench, and remove the oil filter in a counterclockwise direction with a special oil filter paint tool.

Then use a special tool to install the new filter, and tighten, install the oil plug, insert the oil dipstick, introduce a barrel of oil of 4 liters into the oil filling hole, wait for a certain period of time, check the oil level height of the oil dipstick, meet the requirements, the engine vehicle, check whether the oil pressure gauge is normal, and visually check whether there is oil leakage from the bottom screw and the oil filter, etc., 15 minutes later, then pull out the oil dipstick, and check whether the oil level meets the requirements.

Engine oil can lubricate, clean, cool, seal, reduce wear, prevent rust and corrosion of the engine. The engine is the heart of the car, and there are many metal surfaces in the engine that rub against each other, and these parts move fast, the environment is poor, and the operating temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life.

1. Burning engine oil in a cold car: When the temperature of the car is not completely warmed up, the engine exhaust pipe emits a lot of blue smoke, but it is normal after the car is heated. This phenomenon is caused by the aging of the valve oil seal.

Due to the decrease in temperature, the valve oil seal of the rubber spring cavity of the valve oil seal is stiff and cannot be completely sealed, and the oil leaks from the valve into the combustion chamber and burns the above phenomenon.

2. Hot car burning engine oil: After the car reaches the normal temperature, the exhaust pipe still emits blue smoke, which indicates that the piston ring has a poor sealing and burning phenomenon. Due to the poor sealing of the piston ring, the oil directly enters the combustion chamber through the piston ring leakage under the action of the oil pump, and there is a phenomenon of blue smoke from the exhaust pipe.

There are several reasons for this phenomenon, such as: the aging of the material, the carbon deposit is stuck, and the cylinder liner is worn too much.

The main reason for burning engine oil is two aspects, one is the problem of accessories, waste gas valve, valve seal, cylinder pulling, and insufficient cylinder pressure. The second is that the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the oil service life is too long, and the piston ring is stuck, and the more common situation is that the piston ring is stuck.

Eliminate the problem of accessories, most of the reason for burning engine oil is piston ring stagnation, stagnation is from the oil circuit, the oil temperature is 110 degrees, and the oil circuit is not clean for a long time caused by high temperature, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, the oil inside will be dried and scabbed for a long time, and the stagnation of a cylinder is 5000 kilometers of a liter of oil, at this time, the working conditions of other cylinders will also begin to be bad. Soon the 4 cylinders were stuck, and it became a 1000-kilometer hood or even a liter of oil for hundreds of kilometers. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

I don't know if your car has cleaned the oil road and carbon deposits before? There are two ways to solve the problem of burning engine oil, one is overhaul, and the second is PNF repair agent. In the case of overhaul, the cost is very high, the vehicle depreciates quickly, and the later run-in is also very troublesome.

I've seen riders repair it with PNF repair agent before, you can refer to it.

Find out the cause of Suteng burning engine oil and quick solutions.

If it is not severe, a restorative can be added. After adding it a few times, there is almost no trace of oil burning, and the effect is quite obvious. If none of the above works, the situation will be more serious and the engine will need to be repaired.

The method of judging whether Volkswagen Sutar burns engine oil;

1.The exhaust pipe is dark.

Wipe the inner wall of the exhaust pipe first, and then wipe it after a week. If the exhaust pipe is dark, it means that the vehicle is burning oil.

2.Cold cars emit blue smoke when they start in the morning.

Pay attention to the exhaust pipe outlet when starting the cold car in the morning. If blue smoke comes out of the exhaust pipe during the initial phase, the vehicle is burning oil. This method is best done by two people, one person starting the vehicle and the other person taking care of the observation.

Because the time of blue smoke is short, and the time for vehicles to appear will be long.

3.Blue smoke appears when the throttle is large.

Blue smoke appears when the vehicle accelerates sharply or presses on the accelerator on the spot, and almost none. This situation indicates that the fuel burning of the vehicle is already serious and should be repaired as soon as possible.

4.Blue smoke from the grease nozzle.

If the vehicle starts to emit blue smoke from the fuel injector except the exhaust port, it means that the symptoms have reached the middle and advanced stages, and the oil burning is very serious, and you need to seek medical attention as soon as possible to avoid further injury.

What to do if the Volkswagen Sutar engine burns oil If it is not serious, you can add a repair agent. After adding it several times, there is almost no trace of burning oil, and the effect is quite obvious. If the above methods do not work, the situation is more serious and the engine needs to be repaired.

How to tell if Volkswagen Sutar burns oil:1. The basal trachea is very dark.

Wipe the inner wall of the exhaust pipe first, and then wipe it after a week. If the exhaust pipe is dark, it means that the vehicle is burning oil. 2.

This cold car emits blue smoke when it starts in the morning. Pay attention to the exhaust pipe outlet when the cold car starts in the morning. If the exhaust pipe emits blue smoke during the initial phase, the vehicle is burning oil.

This method is best done by two people, one person starting the vehicle and the other person observing. Because the time of blue smoke is very short, it will take a long time for vehicles to appear. 3.

Blue smoke occurs when the throttle is large, or when the vehicle accelerates quickly or when the throttle is pressed on the spot, but is almost non-existent at idle. This situation indicates that the fuel burning of the vehicle is already serious and should be repaired as soon as possible. 4.

Blue smoke from the fuel injectorIf the vehicle has blue smoke from the fuel injector in addition to the exhaust port, it means that the symptoms have reached the middle and late stages, and the oil combustion is very serious, and you need to seek medical attention as soon as possible to avoid further injury.
