Engine oil user guide is the main feature of an engine oil and is important for product selection VISCOSITY GRADE: Signification of grades yy W- xx xx refers to viscosity when cold yy refers to viscosity when hot (measured at different temperatures) (measured at 100 °C) The higher the viscosity when hot, the more viscous the oil is. The lower the viscosity when cold, the more fluid the oil is at low temperatures and the more easily it can be pumped. POINTS TO REMEMBER New-generation engine oils and those currently being developed by TOTAL are of increasingly fluid grades: 0W-20, 5W-20, 0W-30 and 0W-16. For example, a 0W-20 or 5W-30 oil will make start-ups easier and will protect engines during trips to cold regions. These high technology “fluid” oils will meet the requirements of recent engines. For example, a 15W-40 or 20W-50 oil has been developed for use in hot countries, and their “viscous” nature makes them suitable for older engines. How to read a product label for product selection?
