How often to change the lubricating oil during vehicle maintenance will not hurt the car

Hello, the engine lubricating oil is generally replaced once every 5,000 kilometers or 6 months, the front and rear axle manual transmission and manual transfer case are generally replaced once every 20,000 to 30,000 kilometers, and the automatic transmission and electric transfer case are generally replaced once every 45,000 kilometers!

Indeed, it is easy to buy a car and it is difficult to maintain a car, and the most critical part of car maintenance is the engine oil, which is known as the blood of the engine, and it is by relying on its lubrication effect to ensure the normal operation of the vehicle. Therefore, the question of how often to change the engine oil has always been a topic of discussion among car owners. Basically, in the manual of every car, there will be a maintenance interval.

In the case of "general driving", 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. However, "normal driving" refers to driving on highways a lot, but urban driving, especially on congested roads, is considered "wear and tear driving". How often should you change the oil for "attrition driving"?

We recommend doing it between 5000 km and 7500 km. How often to change the engine oil Oil selection Because the engine oil is divided into gasoline engine and diesel engine according to the type of engine, the engine oil is also divided into gasoline engine oil and diesel engine oil, the quality classification of engine oil uses API S followed by an English letter and API C followed by an English letter to represent gasoline engine oil and diesel engine oil respectively, and the lower the alphabetical order of the heel, the higher the level. If the API SH grade is higher than the API SG grade, it is important to determine whether to use gasoline or diesel engine oil when choosing engine oil.

If the packaging of the engine oil indicates API SH CD, it means that the oil is used as a gasoline engine oil and as a diesel engine oil, the grade is CD. The selection of engine oil should be determined according to the requirements of the manufacturer's manual, and the appropriate quality level or higher should be used. The choice of engine oil also takes into account the change of seasons.

Because the viscosity of the oil changes with temperature, the viscosity becomes thicker in winter and lower in summer, so in very hot areas, try to choose an oil with a slightly higher viscosity. In the colder season, a thinner oil can be used. But now high-quality motor oils can be used in a variety of climates at the same time.

How often to change the engine oil according to the engine The requirements of the new engine design, due to the use of electronically controlled fuel injection, catalytic converter, EGR, PCV and turbocharging, intercoolant and other technologies, the working conditions of the engine are more stringent, and the selection of high-quality engine oil can also extend the engine life, reduce fuel consumption, reduce wear, extend the oil change interval, save oil, save maintenance costs and improve efficiency. High-grade engine oils can be used as a substitute for low-grade engines, while low-grade engine oils cannot be used in high-grade engines. Hope, thank you!

As far as I know from Universal Lubricant Technology, lubricating oil is mainly used for lubrication, cooling, rust prevention, cleaning, sealing and buffering, etc., to protect machinery and processed parts. So it is recommended to change it once a month, this is a personal opinion, ha, hope.

The standard is 5,000 kilometers every 3 months. The car oil change is changed by mileage, the general mineral oil can be changed every 5000 kilometers, and the synthetic engine oil can be extended to 8000 to 10000 kilometers. In terms of time, a car that has driven less than 5,000 kilometers for half a year should also consider changing the engine oil after half a year.

If the oil is not changed for a long time, the lubrication effect of the engine oil will be reduced, and the internal parts of the engine cannot be lubricated when the engine is working, which will lead to the wear of the internal parts of the engine and shorten the service life of the engine.

As a kind of machinery, the engine has its common requirements for lubricating oil compared with general machinery, such as appropriate viscosity, certain performance requirements such as anti-oxidation, anti-wear, anti-corrosion and viscosity temperature. But the engine is a special kind of machinery, and its requirements for lubricating oil have its special side. If you are using general engine oil, then you should always check the quality of the engine oil, and poor oil lubrication will damage the vehicle.

When the oil has been used for half a year, check it once a month or before leaving the car, take out some oil from the dipstick to see the oil level and the quality of the oil. The combustion gas in the combustion chamber will leak to the crankcase through the gap between the piston, piston ring and cylinder liner, and these combustion gases are the gases and some particulate matter (soot) produced by the complete and incomplete combustion of fuel and a small amount of lubricating oil, which usually become the main component of the crankcase blow-by, which will pollute the lubricating oil and promote its oxidation under certain conditions.
