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?
