Oil problems in car maintenance

The issue of oil in car maintenance should be well understood by every car owner!

Vehicle maintenance is one of the most basic programs that every car owner must go through to ensure the longevity and driving comfort of their vehicle. Vehicle maintenance is a very common concept, mainly including oil, oil filter, gasoline filter, air conditioning filter, transmission fluid, brake fluid, spark plugs, antifreeze and other cleaning, inspection and replacement. Generally speaking, vehicle maintenance can be categorized into major and minor maintenance according to time and mileage. Minor maintenance is based on 5,000 kilometers, mainly replacing oil, air filter and oil filter; major maintenance is based on 10,000 kilometers, including the inspection and replacement of all items. Today we are going to talk about the oil in 5000 kilometers maintenance.

Classification of oil

Oil is a very important part of the engine. Its main function is to lubricate and reduce wear and tear, assist in cooling and prevent corrosion inside the engine. It is also the most basic guarantee to ensure the service life of the automobile engine and driving safety. Generally speaking, different vehicles need different oil to ensure that the vehicle engine is not damaged.

API engine oils are divided into two categories: the "S" series represents gasoline engine oils, whose specifications are: API SA, SB, SC, SD, SE, SF, SG, SH, SI, SJ, SK, SL, SM, SN

And the diesel engine oils are divided into the standard types of API CA, CB, CC, CD, CF-4, CH-4, CI-4, CI-4/CI-4+, CJ-4, CK. the highest level of environmental protection is CK. Where C stands for diesel engine oil, the second letter stands for oil grade and environmental standards, and the number 4 stands for four-stroke diesel engines.

The oil is mainly divided by the SAE standard viscosity value. Take any model on the market as an example, such as 10W-40 First of all, the first half of the "w" is the abbreviation of WINTER, which means winter, and 10 is the fluidity of this kind of motor oil in winter. The smaller the first number, the better the fluidity of the oil in winter. However, the following numbers indicate the likelihood of oil dilution at high summer temperatures, i.e., high temperature stability. The larger the following number, the better the high temperature stability. It can also be categorized into other types, but in life it is more commonly categorized as viscous

How do you choose the right oil?

First, go with the type recommended in your vehicle's manual. Look for the recommended engine oil type and engine oil type from the vehicle instruction manual, which identifies the minimum standards for the most balanced performance and filling of engine oil. Therefore, when servicing your vehicle, try to choose the same or higher performance engine oil described in the manual to avoid engine damage and unnecessary breakdowns.

Secondly, engine oil should be selected according to the local temperature. In China, it is mainly divided into northern and southern regions. The winter temperature in the northern region is usually around -10 degrees Celsius, and the temperature in the more northern regions can even be as low as around -30 degrees Celsius. Therefore, it is never advisable to choose engine oil in the ordinary way. It is necessary to choose an oil with lower temperature resistance, i.e., an oil with a lower quantity of oil before use In addition, a predictive choice should be made as far as possible, otherwise a sudden drop in temperature will bring inconvenience or even greater damage to the vehicle.

Third, we should prioritize our own situation. The actual situation of vehicle use is also a more important point when choosing motor oil. Whether the owner of the vehicle is often driving violently, whether the vehicle is used under long-term overloading and heavy loads, as well as some special requirements need to choose a more heat-resistant oil than the specification model.

Lastly: in choosing the right engine oil is the most responsible thing for the vehicle, can effectively improve the service life of the engine, so that the daily use of the vehicle is more comfortable and smooth, to reduce many unnecessary trouble. Improper use of motor oil will bring many irreversible effects to the vehicle engine. As a car owner should know how to maintain their car.
