At the Auto-Oil Advisory Panel (AOAP) meeting on May 9, 2013, 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. announced they are modifying the GF-6 Needs Statement to potentially allow for oils to be formulated to <0.06 percent wt. phosphorus. For GF-5 oils the phosphorus specification is >0.06 and <0.08 percent wt. ILSAC feels passing the Sequence IVB valve train wear test, new for GF-6, will assure adequate engine wear protection so no elemental minimum is needed. Maximum phosphorus level will remain at 0.08 percent wt. to enhance 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. system performance.
Also, during this meeting additional test results were reported on SAE 0W-16 engine oils. SAE 0W-16 engines oils have reported robust engine oil performance similar to ILSAC GF-5 oils with slightly better fuel economy. There is no change to the timeline, proposed first 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. licensing of ILSAC GF-6 remains September 30, 2016. The next AOAP meeting is on June 13, 2013.
