Viskositätsklasse
Viskositätsklasse refers to a system used to categorize lubricants based on their viscosity, which is a measure of a fluid's resistance to flow. Different viscosity grades are defined by standards organizations to ensure that lubricants perform as expected under specific operating conditions, particularly temperature.
The most widely recognized viscosity classification system for engine oils is the SAE (Society of Automotive
Other viscosity classification systems exist for different types of lubricants and applications, such as industrial oils
