INTERNATIONAL STANDARDS OF LUBRICANTS
The SAE (Society of Automotive Engineers) grade determines oil's fluidity at high and low temperatures. Motor oil should remain efficient no
matter the weather conditions (temperatures' range from -30° to +40°).
Total quartz INEO ECS's SAE grade of 5w30 indicates viscosity index at
low temperature (5) and at operating temperature (30).
The API (American Petroleum
Institute) standard classifies motor oils according to various criteria such as
detergency, wear resistance,
anticorrosion etc., and according to their uses and performance.
The European Automobile Manufacturers' Association has developed a standard under its name ACEA and which takes the form of a code (category/class).
There are three ACEA categories:
The "Euro" standards:
