Overview
SN Grade is a multigrade gasoline engine oil made from synthetic base oil and additives for modern gasoline cars, offered in four grades from 0W20 to 10W40. Available grades: SN 0W20, SN 5W30, SN 5W40, SN 10W40. API lists SN as a current category for gasoline automotive engines of model year 2020 and older.
Each grade is listed separately in the specification table with its viscosity at 100 °C, viscosity index, flash point, pour point, density and base number, so grades can be compared directly before ordering.
Application
Modern gasoline cars
Vehicles whose handbook calls for API SN — per API, gasoline engines of model year 2020 and older.

Feature
Choice of viscosity grades
4 grades in one product line, so a fleet can standardise on one API level across different climates or engine requirements.
