Many people are caring for their own cars through buy the lubricant oil by theirself, or going to the repair shop outside, they will face the problem of choosing their own oil. Is it fully synthetic or ordinary? What brand? What viscosity? What level? The brand of oil is not very important, as long as the oil is genuine, it is no problem to choose several major brands. Is it fully synthetic or ordinary? If the original car is use ordinary lubricant, it can be used ordinary, you can also choose a better full synthesis.
As for the viscosity of the oil, you must choose the same as the original engine oil, otherwise it's easy to have some problems. There is a parameter that most car owners will ignore, that is the oil quality level. The same brand of motor oil, whether it is 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. The oil quality grade is an important criterion developed by the American Petroleum Institute to measure the quality of oil and the quality of oil.
The gasoline engine oil or gasoline Engine Oil Additive Package is start with S. From SA, SB, and SC to SN, the letters after S are sequentially increased. The lower the letter, the higher the oil quality level. Oils like SA, SB, and SC are decades old, and they are no longer visible. The lowest grade of oil that can be bought today is SJ, which is almost the same level of oil used in vehicles almost a decade ago. The SL, SM, and SN levels are now available for purchase. The SN is currently the highest level. Most of the new car manufacturers now use the SN level, so the SN level is now very much.
When you choose the grade of lubricant oil, you can't choose the is lower than level of the original engine oil . If the original factory uses the SN level, you should also choose the SN level instead of the SJ level. If the original factory uses SJ level, you can use a higher level.
