About GF-5 Specification
Introduced in October 2010, the ILSAC GF-5 specification established stricter engine oil standards and fuel economy requirements. The specification was designed to ensure increased compatibility and protection of modern automotive engines, including high-temperature deposit protection for both pistons and turbochargers, more stringent sludge control, improved fuel economy, enhanced emission control system compatibility, seal compatibility and the protection of vehicle engines operating on ethanol-containing fuels up to E85.
About dexos1™ Gen2
Introduced in 2015, the dexos1™ Gen2 specification by General Motors is designed to provide increased engine protection and performance, especially with regard to low-speed pre-ignition protection for turbocharged engines with small displacements. It is recommended for use in all General Motors vehicles regardless of make, model or year.
