Recently, a friend of the author raised the next question: his car has been changing the original engine oil at the special service station, because the car has been driving more than 200,000 kilometers, in order to better maintain the engine, he wants to replace it with a higher level Is it possible to ask if it’s ok? I think this problem is universal among car owners, so I have compiled a short article for your reference.
The original engine oil can fully meet the needs of the engine work, if your economic conditions permit, of course you can choose a higher-grade engine oil. Generally, two indicators should be paid attention to when selecting engine oil. One is the choice of the use level, and the other is the choice of the viscosity level. After determining the level of engine oil, domestically-made brand-name engine oil should be selected first, because many domestically-made engine oils produced by regular manufacturers can meet international standards and are cheap and can be used with confidence.
Choose and uselubricating oilSome common sense issues should be paid attention to:
(1) Gasoline engine oil and diesel engine oil are generally not universal. There are exceptions to this principle, such as FAW—public(Volkswagen) The original engine oil of the company's Bora car can be used in the gasoline Bora and diesel Bora cars, but only incarWhen the manufacturer has specified or marked that the engine oil is a general-purpose oil for gasoline and diesel engines, it can be used within the marked range.
(2) The viscosity of the selected oil should be appropriate, and the oil with high viscosity should not be selected. Some users believe that the higher the oil viscosity, the better the lubrication effect. This is a wrong view. Under the premise of ensuring the reliable lubrication of the engine, the oil viscosit

(2) The viscosity of the selected oil should be appropriate, and the oil with high viscosity should not be selected. Some users believe that the higher the oil viscosity, the better the lubrication effect. This is a wrong view. Under the premise of ensuring the reliable lubrication of the engine, the oil viscosity should be as small as possible. Choosing an inappropriate high-viscosity oil will increase the running resistance of the engine and increase the fuel consumption. Except for use in summer, high-viscosity engine oil is only suitable for some severely worn engines.Similarly, do not choose oil with too low viscosity, otherwise it may cause the oil pressure to be too low, the lubricating oil film strength is not enough, or makePiston ringThe seal is not tight, so the oil should be selected correctly according to the vehicle condition and season. For the general purpose motor oil in winter and summer, it can be used all year round.
(3) Adhere to the principle of economical applicability. When selecting the use level of oil, high-grade oil can be used on engines with lower requirements, but using too high-grade oil will cause waste. It is strictly forbidden to use low-grade engine oil in engines with higher requirements, otherwise it will cause early engine wear and damage.
(4) Engine oil often turns black after using it for a short time. At this time, many users think that the quality of engine oil is not good. In fact, this is usually a normal phenomenon. Engine oil not only has the function of lubrication, but also has the function of cleaning. It can disperse and clean the carbon deposits attached to the engine. When the oil is changed, the carbon deposits can be discharged with the oil. Therefore, once there is a phenomenon of black oil in a short period of time, the cause should be carefully analyzed.
(5) When the engine is working, organic oil is consumed under normal conditions, but it is a problem of large amount and small amount. Generally, the consumption is relatively large during the running-in period. Because the oil consumption is different, the user should check the oil level regularly through the oil dipstick, and replenish it in time when it is found to be insufficient. If the oil consumption increases suddenly, you should check for oil leakage.pistonRing orValveOil sealWhether it is worn or not, no matter what the reason, it must be checked and eliminated in time.
In principle, engine oils produced by different manufacturers contain different base oils and additives, which may cause incompatibility or reaction during mixed use. Therefore, different brands of engine oils cannot be mixed, but they can also be temporarily mixed under special circumstances. Replace all engine oil in time. (Asia News Car Network)
