Read a product name in four layers: the ALFA brand, product family, viscosity grade or code, and any added descriptor. The family points to the broad application, while the grade provides the first technical comparison point.
A viscosity grade describes fluid behavior within a defined classification system, complemented by the performance requirements and specifications stated in the product document. An organization or manufacturer approval is listed when supported by the current documentation. Use the product page, data sheet, and equipment manual together for an accurate comparison.
Build a four-column table with the full product name, grade, exact specification or performance wording, and document number or link. Add the document revision and date, then select the product that matches the equipment reference and defined operating conditions.
