What Does Advanced Full Synthetic Engine Oil Mean?
1 Answers
Advanced full synthetic engine oil refers to high-quality lubricant products made entirely from PAO (Polyalphaolefin) or artificially synthesized esters, with the word "synthetic" labeled on the oil container. Relevant information is as follows: 1. Classification: Engine oils are mainly categorized into mineral oil, semi-synthetic oil, and full synthetic oil. Full synthetic oil is the highest grade of engine oil, with the main difference between full synthetic and semi-synthetic oils being that full synthetic oil has a wider temperature range and longer service life. 2. In terms of grade: Synthetic oils are mainly represented by SL, SM, and SN grade oils, while full synthetic oil represents the highest grade of engine oil, thus using the SN grade, which is the latest engine oil standard. The API on engine oil stands for the American Petroleum Institute, with grades ranging from SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, to SN, with each subsequent grade representing a higher standard.
