Grade names are commercial enquiries, not universal specifications. SN/N/R numbers are refiner-specific; cSt must state temperature. ISO VG describes viscosity at 40°C. II+ and III+ are market labels. GTL is a process; re-refined is an origin. Confirm API group and compatibility from the actual TDS and batch COA. Base stocks are ingredients, not finished engine oils or API-licensed lubricants.
