How to choose engine oil?

1. What is the best lubricant for your car? The quality of lubricating oil depends on the base oil. Originally, 80% of lubricating oil was base oil. Only the lubricating oil produced with high-quality base oil can better help the engine to reduce wear and prolong its life, prolong the oil change cycle and reduce the frequency and difficulty of maintenance. He took SK lubricating oil, which is the most popular among car owners in this store, as an example. Because this lubricating oil is made of internationally renowned high-grade YUBASE base oil, it has strong viscosity retention performance at high and low temperatures, can form enough oil film on the engine surface, has strong wear resistance, and can ensure the engine to run freely in extreme temperature environment.

2. Does the oil turn black and need to be changed immediately? Although engine oil is prone to oxidation and deterioration when working at high temperature, with the continuous improvement of lubricating oil quality, especially the use of multi-grade oil, the blackening of engine oil does not necessarily mean deterioration. Because the detergent dispersant added in modern engine oil will disperse the deposits on the parts in the engine oil, for example, the detergent dispersion performance of SK lubricating oil can clean the sludge and carbon deposits produced in the engine to the maximum extent, which will lead to the black color of the engine oil after a certain period of time. Therefore, he suggested that car owners should not change the oil just because the oil turns black, but should change the oil regularly according to the quality to reduce unnecessary waste.

3. Is it necessary to add various additives? At present, the benefits of engine oil additives in the market have been heated up, and various anti-wear agents and cleaning agents sold are numerous. In this respect, because each brand of engine oil has certain standards, not any additive will be miscible with any engine oil. If it is immiscible or chemically reacts with the components in the original engine oil after being added, it is likely to cause changes in the properties of lubricating oil, resulting in lower efficiency of lubricating system, deterioration of oil products and aggravated mechanical wear. For example, well-known lubricants such as SK are all blended with base oil and high-tech additives with exclusive patented technology.
