Buick GL83 0S has not reached the time of maintenance, but what is the effect of the abnormal black

Hello: The oil is black and accompanied by a strong smell of gasoline, such an oil has a great impact on the engine. Poor lubrication leads to increased wear on individual parts, such as piston rings and cylinder walls, crankshaft shaft diameter, and connecting rod shaft diameter.

Normal. It is very normal for the engine oil to be very black, the engine oil turns black because the engine oil plays a role in the operation of the engine, in addition, when the engine is working, the temperature and pressure are very high, the engine oil has been circulating in this environment, and it will slowly oxidize and turn black.

It is not caused by the deterioration of the oil. Therefore, if the oil is very black, if you don't use inferior oil, if you don't maintain the car according to the maintenance manual, under normal circumstances, the oil is very black, it is no big problem.

The composition of the motor oil is base oil + additives. This is true for mineral, semi-synthetic or fully synthetic oils. However, these are only the base oils of engine oils, and the types and formulas of additives seem to be similar to those actually used, but they are very different.

The main role of additives in lubricating oil is to improve and enhance the various properties of engine oil, so that the oil has better lubrication, cleaning, cooling, sealing, anti-rust and anti-corrosion, cushioning and shock absorption. The types of additives can be as many as more than 10 kinds, according to the formula needs to increase and decrease the amount to meet the characteristics, that is to say, the higher the grade oil, not only the better the base oil used, the more types of additives, the better the quality and naturally.

There are many types of additives in motor oil, and one of them is called"Cleaning dispersants"。It can be chemically neutralized with gum, sludge and other chemicals in engine oil. In other words: it can remove the glue, sludge and other dirt inside the engine"Wash it down"。

The carbon deposits and oil sludge in these engines are all black in color, and the oil will naturally turn black, and after being washed off, the oil color will naturally turn black, so it is very normal for the oil to be very black.

It is precisely because of the high content of dispersant that the engine oil has a strong cleaning ability"black fast", while the oil with a low content of cleaning dispersant is just the opposite. If you use thousands of kilometers of engine oil, the color has not changed at all, and it is still crystal clear, which is abnormal, and it is likely that the cleaning ability of this engine oil is too poor, resulting in it"Nothing washes off".

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.

Summary. Hello, happy to answer your questions.

Will the Buick GL 8 be prompted when it is short of oil?

Hello, happy to answer your questions.

Hello, according to the problem you described, Buick GL8 lacks too much oil, and the oil lamp will report that there is no other alarm for the hole, and it is recommended to check whether the oil is missing regularly.

I bought a new GL 8 car and one of the lights on the dashboard came on.

You take a picture of it.

What is the sign of the lack of glass water.

There is a sign of a light rain on both sides of the sign.

This is the engine fault light, and if there is a problem with the engine system, it is checked with a diagnostic computer.

This diagram marks what is missing.

It's not that there's something missing, it's a matter of checking for a problem with the engine system.
