You don't need to choose your own engine oil when going to a 4S store for maintenance. The engine oil used must be suitable for your car. Nowadays, many people take care of their own cars, purchase their own engine oil, or go to external repair shops for maintenance, and they will face the problem of choosing engine oil. Should we use fully synthetic or regular ones? What brand does it use?

You don't need to choose your own engine oil when going to a 4S store for maintenance. The engine oil used must be suitable for your car. Nowadays, many people take care of their own cars, purchase their own engine oil, or go to external repair shops for maintenance, and they will face the problem of choosing engine oil. Should we use fully synthetic or regular ones? What brand does it use? What viscosity is it? What level is it? Actually, for beginners, they don't know how to choose. Today, let's talk about the quality level of engine oil. Don't forget to check when choosing engine oil.

       Quality grade of engine oil (1)

     First, let me talk about the first few questions. The brand of engine oil is not very important, as long as the engine oil is genuine, it is not a problem to choose several common major brands. Fully synthetic or ordinary? What is the viscosity of engine oil? Use whatever type of original car you want. The original car used ordinary, so you can use ordinary or choose a better fully synthetic. As for the viscosity of the engine oil, it is important to choose one that is the same as the original engine oil, otherwise some problems may occur. Finally, there is one parameter that most car owners will overlook, which is the oil quality level that will be emphasized below. The same brand of engine oil, whether fully synthetic or ordinary, has different quality levels. The higher the quality level, the better the performance of the oil, and the more expensive the price.

       Quality grade of engine oil (2)

       The quality grade of engine oil is an important standard established by the American Petroleum Institute to measure the quality of engine oil. The engine oil used in gasoline engines starts with S, from SA, SB, SC all the way to SN, with the letters following S increasing in sequence. The later the letter, the higher the oil quality level. Oils like SA, SB, and SC are all from decades ago and can no longer be seen. Currently, the lowest grade of oil available is SJ, and most of the oil used in cars from almost a decade ago was of this grade. SL, SM, and SN levels are increasing in order and can now be purchased. SN is currently the highest level, and most new car manufacturers use SN level oil, so there are a lot of SN level oil available now.

When choosing the oil grade yourself, it should not be lower than the original factory oil grade. If the original factory uses SN grade, then SN grade should also be chosen instead of SJ grade. If the original factory uses SJ grade, a higher grade can be used. When maintaining in a repair shop, one often only chooses which brand and whether fully synthetic or regular engine oil is used, without mentioning the quality level. In this case, it is necessary to inquire which grade is used. Not to mention that maintenance is very cheap, but poor oil quality is also detrimental to the engine. How to know the quality level of your car's original factory oil? One is to read the maintenance manual, but some can write it, while others cannot. The other is to check the oil drum during maintenance at the 4S store, which specifies the quality and viscosity levels, which are the minimum standards.
