Why does the higher end car engine oil burn out faster?

Most of the engine oil burning in high-end models is directly related to the pursuit of high performance by engine over-pressing.

Because the emissions of high-end cars are relatively high, his consumption is high.

Because its configuration and emissions are very high, it is normal, and the faster his oil is consumed.

High-end cars are equipped with large engine displacement, so fuel consumption is high.

This is because the more high-end the car, the displacement of his car is very large.

It is necessary to have a high degree of running-in between the various parts of the people, so it should be moisturized with oil.

Because the configuration and emissions are also very high, just like the Audi A6 with a foot on the accelerator 15 yuan.

Because of its high emissions, the equipment requires high energy consumption, so it consumes quickly.

Because of its high configuration and emissions, the amount of oil consumed naturally is high.

There are many reasons why too much oil is consumed. 1. The piston ring installation turns the piston ring of oil scraping into pump oil, 2. The piston ring, piston and cylinder wall are seriously worn, 3. The oil seal on the intake and exhaust valve is damaged, so that the oil escapes into the combustion chamber, 4. The valve chamber cover, the oil pan, the oil drain plug, the timing gear, the oil seal before and after the crankshaft, the camshaft oil plug, the oil filter, the oil seal of the gasoline pump and other parts The sealing gasket is damaged.

The engine burns the oil, so that the oil is consumed quickly, to see if the exhaust is blue smoke.

The oil consumption is increasing, and four liters of oil are added for 5,000 kilometers, and it turns out that it is blocked here.

After the vehicle is used for a period of time, there may be high oil consumption, which is what we usually call the phenomenon of burning oil. Excessive oil consumption not only causes waste and pollutes the environment, but also pollutes the spark plug and increases the abnormal wear of the cylinder due to carbon deposits after combustion. The main reasons for excessive fuel consumption are as follows:

1. The sealing surface of the engine is not tightly tightened or the sealing gasket is aging, the oil seal is aging and damaged, etc., which will cause oil leakage, resulting in large oil consumption. 2. Automobile oil is burned in the combustion chamber. There are four main ways for oil to enter the combustion chamber:

a Valve oil seals deteriorate, causing oil to enter the combustion chamber through the valve guides. b The valve guide rod and valve guide are seriously worn, and the gap is too large, and the oil will enter the combustion chamber along the gap. c If the gap between the piston ring and the cylinder wall is too large, or the piston ring is damaged, the oil will also enter the combustion chamber for combustion.

d.When the crankcase ventilation system fails, excess oil in the crankcase passes through the crankcase ventilation duct and enters the combustion chamber for combustion. 3. Too much oil filling, when the crankshaft rotates, a large amount of oil is splashed into the cylinder for combustion, which not only increases the consumption of oil, but also increases the movement resistance of the crankshaft and reduces the power output of the engine.

Car oil is consumed too quickly, this part is easy to cause, come in and teach you a trick.

The right engine oil is the best, and the expensive one may not be good. Generally speaking, the more expensive oil refers to the fully synthetic engine oil, and its performance is often much better than that of mineral engine oil, but it cannot be said that mineral engine oil is not good. Usually fully synthetic motor oil is used in engine speed and compression ratio.

Synthetic or semi-synthetic motor oils are preferred for high-end sports cars and luxury cars where the engine process is more sophisticated and requires better lubrication and cleaning.

However, for ordinary tens of thousands, hundreds of thousands of family cars, the process accuracy of the engine can not be compared with high-end cars or sports cars, and the engine rarely works at extremely high speeds.

Even better, for engines with poor accuracy, it is easy to cause oil burning.

Or there may be an increase in oil consumption.

In fact, now even the quality of mineral engine oil is much better than the quality of the last century, for ordinary economic cars as long as the filling is the best mineral oil, choose the right viscosity, grade, in the normal use and maintenance of the engine to drive hundreds of thousands of kilometers is no problem, no need for overhaul. If you don't believe it, go ask my brother, break Xiali.

Ordinary mineral engine oil does not need to be maintained for more than 600,000 kilometers, and the average private car user often sells or obsolutes the car before driving less than one-third of the mileage.

Some friends think that synthetic engine oil can run longer mileage and then change it is not very expensive, which has to be from two aspects.

First, the car maintenance that is now formulated by the 4S shop.

The mileage has not changed for decades, but the engine technology and the quality of the lubricating oil are constantly improving, so for many private cars with a good car environment, it is no problem to change the mineral engine oil to 10,000 kilometers.

Second, in addition to lubrication, engine oil also has functions such as cleaning, heat dissipation, and sealing, if the environment used is very harsh, sandy, and dusty, even the synthetic engine oil will quickly deteriorate and need to be replaced.

Because the engine oil also has a sealing effect, and for the reason that the synthetic engine oil we just mentioned has good ductility, some heavy-duty vehicles and ordinary processes are not very accurate for low turbocharging.

The use of fully synthetic motor oil in the vehicle can lead to excessive oil consumption or poor sealing. Combustion chamber gases enter the oil, resulting in a decrease in the early deterioration of the oil.

Therefore, the engine oil is not expensive, you must choose the right one, do not blindly listen to the flickering of the business, because with expensive engine oil their profits are better, there are some 4S shops for the maintenance strategy of the economic car is to fool the customer with synthetic or semi-synthetic oil, and deliberately leave a little, tell the owner that you can continue to use it next time, the owners should keep their eyes open, the little people whose money is not blowing in the wind, and the unnecessary money is still kept to do the necessary things.

The maintenance strategy of the economic car is to fool the customer with synthetic or semi-synthetic oil, and deliberately leave a little, telling the owner that you can continue to use it next time, and the owners should keep their eyes open.

Hello The reasons for the rapid consumption of motor oil in a car are: oil leakage; The crankcase is ventilated, and the pipeline is blocked; Wear of valve stem and valve guide; 4. The valve stem oil seal is worn or worn; 5. During maintenance, the piston ring is installed in reverse, so that the oil enters the combustion chamber; 6. The piston ring is stuck in the ring groove due to gelation or the piston ring is seriously worn; 7. Improper selection of lubricating oil, too small viscosity; 8. Excessive lubricating oil. Engine oil is a class of substances that are enhanced with additives in base oils, mainly containing anti-wear additives and detergents, dispersants and multi-grade oil viscosity index improvers, and engine oil is used for lubrication of internal combustion engines.

The following are the reasons for the fast consumption of automobile oil: 1. The piston ring is worn or damaged, and the piston ring piston ring opening interval angle changes, resulting in a large amount of oil entering the combustion chamber and causing oil burning. 2. Serious wear of the cylinder liner also causes the oil to flow into the combustion chamber to burn the oil.

3. The oil level of the crankcase is too high, or the oil seal of the crankshaft is aging and cracking, resulting in oil leakage. 4. Poor ventilation of the crankcase causes the fuel vapor in the crankcase to be unable to be discharged, and the oil leaks due to the increase in crankcase pressure. 5. The engine speed is too high, and the current engine is a high-speed engine, and the excessively fast speed must have a certain increase in fuel consumption.

6. The consumption of gasoline is different depending on the use environment of the car. For example, in mountains and flat terrain, the quality of fuel and the proficiency of the driver will have an impact on the oil consumption of the engine.

Hello, not the more expensive the oil, the better, the quality of the lubricating oil identification:

1.Carefully observe the color of the lubricant.

Domestic genuine engine oil is mostly light blue, the color is bright, the flow is uniform, all the color is uneven, flowing with different color lines are shoddy or deteriorated lubricating oil. The color of imported lubricating oil is golden and slightly blue, crystal clear, the oil drum is exquisitely manufactured, the edge of the pattern code is clear and neat, and there is no color leakage and overlapping, otherwise it is a fake.

2.Look closely at the packaging.

Poor quality lubricating oil packaging is of poor printing quality and the handwriting is not clear. However, there are also counterfeit lubricants that use genuine packaging, which is difficult to identify.

Generally speaking, the outer packaging quality of authentic products is relatively good, the handwriting on the packaging box is clear, the overprint color is bright, marked with the product name, specification model, quantity, registered trademark, factory name, factory address and ** number, etc., with a certificate of conformity and inspector seal.

3.Smell the smell.

Qualified lubricating oil should have no special odor, if the smell is pungent and peculiar, Fu Zaoxiang is a deteriorated or inferior lubricating oil.

Choose the right one, don't choose the one of Gui Tongsen. The lubricating oil market is mixed, and it is generally difficult to distinguish the distribution of lubricating oil based on appearance alone. Lubricating oil, it is best to go to a regular 4S shop for maintenance.
