GF5 is a specification for engine oil. Engine oil that meets the GF5 specification can improve fuel economy and effectively reduce pollutant emissions, thereby further protecting the environment. Before GF5, there were GF1, GF2, GF3, and GF4 specifications, with later versions offering stronger performance. GF oil is an abbreviation for ILSAC GF5, where ILSAC refers to the International Lubricant Standardization and Approval Committee, a certification system for engine oils jointly established by American and Japanese automobile manufacturers' associations. GF5 engine oil has passed the synthetic oil certification of the American Petroleum Institute (API) and belongs to the high-grade SN category, enhancing fuel-saving performance on the basis of all SN-level specifications.
