The importance of motor oil to the car is self-evident, without it, the car engine will suffer serious damage, making it difficult for the car to move an inch. Engine oil is not only responsible for lubrication, it also has the functions of cooling, cleaning, vibration damping, sealing, etc. At present, the oil grades on the market are intricate, often so that car owners do not know how to choose, in fact, there are only two main indicators of engine oil, figure out the specific meaning, on the line.
Viscosity indicator. According to the SAE method, there are 6 types of oil for winter, 5 types of oil for summer, and 16 kinds of general oil for winter and summer.
Winter oil grades: OW, 5W, 10W, 15W, 20W, 25W. The symbol W represents winter, the smaller the number before W, the smaller its low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature.
Summer oil grade, 60. The higher the number, the greater its viscosity and the higher the applicable maximum temperature.
Winter and summer general oil grade: 5w w w w w The smaller the number for the winter portion and the larger the number for the summer portion, the larger the applicable temperature range.
Quality indicators. According to the API quality classification, engine oil is divided into gasoline engine oil series (i.e., S series) and diesel engine oil system (i.e., C series), and the oil products of each series are arranged in alphabetical order (A, B, C, D, E, F), and are divided into several grades, and the lower the letter ranking, the higher the grade.
Selection method. The marking on the outer packaging of engine oil currently sold on the market consists of two parts: SAE viscosity classification level and API quality classification level. It usually starts with SAE and is followed by a viscosity code; The engine oil label classified by API quality generally omits the API and directly marks the quality grade code.
For example, the designation SAE10WSD indicates a winter gasoline engine oil with a viscosity classification of SAE10W and a quality level of API SD; The designation SAE30SD indicates the viscosity classification SAE30, and the quality grade is APE SD for summer gasoline engine oil; The label is SAE10W 30SD (or SAE10W 30SD), which indicates that the viscosity classification is to meet both SAE10W and SAE30 winter and summer general purpose gasoline engine oil, and its quality grade is API SD grade.
When choosing engine oil, you can combine the local maximum and minimum temperatures, and refer to the "User Manual" of the car. If you choose an oil that is too viscous, it will increase the resistance to movement and consume engine power; If you choose an oil with too little viscosity, the lubrication quality cannot be guaranteed, and it will aggravate the wear of the engine. For engines that have been seriously worn and the gaps between the fittings are large, a higher viscosity oil can be used to strengthen the sealing performance of the fittings.

Antifreeze big brother, if you don't have it, you can go to 4s for free, just add a point, you don't need to change it all, just change it for two years.
-
If the antifreeze is out of stock for less than two years, just add some purified water.
-
It is best to be the original factory, try to use a big brand**, it must be SJ grade engine oil, the specification is APISJ GF-II, and the viscosity is 5W 30

Precautions for adding engine oil to automobiles:
1. When should I change the oil?
In the general driving situation of a new car, if synthetic engine oil is used, the oil can basically be changed every 10,000 kilometers, and some can even be dragged up to 20,000 kilometers. "Ordinary driving" refers to driving on the highway a lot and rarely stopping and walking. However, if you often drive in the city, there are traffic lights when you go to **, you will be stuck in traffic at every turn, and most of the distances of each trip are not more than ten kilometers, this kind of driving method belongs to "attritional driving".
In the case of "weary driving", the engine wears a lot and the oil demands are high. Therefore, it is advisable to shorten the interval between oil changes in order to effectively protect the engine.
2. Choose engine oil.
When buying engine oil, pay attention to four elements.
In general, the following four elements should be paid attention to when choosing automobile engine oil:
a. The choice of engine oil should be selected according to the requirements of the engine, and it is not necessary to use too high-grade engine oil on the engine with lower requirements, nor can the oil of the lower grade be used on the engine with higher requirements.
b. Multi-grade oil should be selected as much as possible, because multi-grade oil has a good protective effect on the engine due to its saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.
c. The quality of some domestic brand-name engine oil is quite good, and it is much lower than that of similar imported products, so it can be used with confidence, and there is no need to blindly pursue "foreign oil".
d. If the engine is in good condition and the temperature is low in season, the oil with low viscosity should be used as much as possible to make the oil circuit smooth. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear.
3. The oil quantity should be slightly lower than the scale on the oil dipstick.
Excessive additions (exceeding the upper limit of the ruler) have bad consequences. Too much oil will increase the rotational resistance of the crankshaft, reduce the output power of the engine, and the excess oil will enter the combustion chamber to participate in combustion, causing the vehicle to burn oil, blue smoke, and increase fuel consumption. Residues from combustion oil (which is mainly made of carbon and are very hard) accumulate on the combustion chamber walls, reducing the combustion chamber space, thereby reducing the compression ratio of the engine, while also accelerating the wear of cylinders and pistons, thus reducing the life of the vehicle.

There are many factors caused by this fault light, this is not easy to say, it is recommended to use a computer to detect it to know what the problem is. As for the problem of adding engine oil in **, open the engine compartment cover and see that the black cover in front of the engine cylinder head is the oil filler directly in front of the condenser, and the exhaust branch is above the car is 30,000 You should know these common sense, and then the engine oil model can not be used indiscriminately, and the Accent uses SF on the line.

Hello,** on the valve cover with the word microphone next to the point, the right point of the 16v is the place where the oil is added.
The engine fault light indicates that the engine electronic control system is faulty, which is generally caused by the damage of a certain electronic component sensor, and it is necessary to use a computer to detect the fault code and repair it for the inspection fault. It is recommended that you go to the 4S store to deal with it.
