What does Castrol Edge FE mean?
1 Answers
Castrol FE engine oil refers to the latest titanium fluid formulation, which does not fall under the category of oil grades. For example, SN and similar designations indicate oil grades, while the titanium fluid series of oils all belong to the SN grade, so there is no conflict between the two. Related information: 1. Castrol FE engine oil: Castrol Edge utilizes advanced titanium fluid strengthening technology, making it a premium high-end engine lubricant. Infused with a liquid titanium formula, it possesses unique oil film self-adaptability, effectively reducing direct metal-to-metal contact under various driving conditions, thereby minimizing friction loss and ensuring optimal engine performance. 2. Oil grades: 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 being higher. SN grade is currently the highest level of engine oil. SJ is the standard from the 1990s, SL is the standard from 2001, SM is the standard from 2004, and SN is the standard from 2010.
