ILSAC GF-6 Overview
To meet changing fuel economy and Mobile sources - Pollutant exhaust gases created by the combustion of fuel. Water and CO2 are not included in this category, but CO, NOx, and hydrocarbons are and are thus subject to legislative control. All three are emitted by gasoline engines, while diesel engines also emit particulates that are regulated. Stationary sources - The release of sulfur oxides and particulates from power stations that can be influenced by fuel composition. Local authorities control the sulfur content of heavy fuel oils used in such applications. standards, modern engine hardware has evolved and requires higher performing lubricants. Engine downsizing, turbocharging, gasoline direct injection (GDI or TGDI), variable valve timing, and the introduction of stop/start, hybrid and electric technologies mean GF-5 tests simply do not measure up to the demands placed on modern lubricants.
The automotive industry’s recent licensing of the supplemental lubricant category American Petroleum Institute. The primary oil and natural gas trade association in the United States. API operates a voluntary licensing and certification program that allows engine oil marketers to use the API Engine Oil Quality Marks if their products meet specific requirements. SN PLUS to mitigate low-speed pre-ignition (Low-Speed Pre-Ignition. Uncontrolled combustion that takes place in the combustion chamber prior to spark in gasoline direct injection (GDI) engines.) observed in vehicles equipped with GDI engines is a start, but there are still more issues that require a better lubricant solution. The new International Lubricants Standardization and Approval Committee. A collaboration between the American Automobile Manufacturers Association (AAMA), Chrysler, Ford, GM, and the Japanese Automotive Standards Organization. ILSAC GF- engine oil specifications target fuel economy, emission system protection, and enhanced engine oil robustness. GF-6 will balance these equally important needs:
- Fuel economy and fuel economy retention
- Emission system compatibility
- Engine oil robustness to protect engines from wear related to idle stop and failures related to LSPI and turbocharger depositing
This performance standard will include two separate specifications – GF-6A to represent the existing ILSAC A measure of a fluid's resistance to flow. A fluid with a higher viscosity flows less easily. grades and GF-6B will be defined for 0W-16 viscosity grade oils only.
