What is the identification of fully synthetic oil?
1 Answers
Imported fully synthetic oil is typically labeled with the letters FULLY-SYNTHETIC or 100% SYNTHETIC, or you can check for labels indicating PAO and ester oil. Here is some relevant information: 1. Grade: The current main grade for fully synthetic oil is SN. API stands for the American Petroleum Institute, and the grades range from SA to SN, with SN being the highest grade available. 2. Composition: Fully synthetic oil models consist of the API quality grade and the SAE viscosity grade. SAE stands for the Society of Automotive Engineers and generally refers to the SAE standard viscosity value. The 'W' stands for WINTER. Viscosity grades for fully synthetic oil include 5W-30, 5W-40, and 0W-30, among others. The first number represents the freezing point temperature, while 40 indicates that the kinematic viscosity standard at 100°C is between 12.5mm2/s and 16.3mm2/s.
