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-5 was first introduced in October 2010 as the minimum performance standard for use in gasoline fuelled engines in passenger cars.
ILSAC GF-5 oils are formulated to improve fuel efficiency and provide improved performance across a wide range of areas including high temperature deposit protection for pistons, improved protection against the formation of engine A thick, dark residue, normally of mayonnaise consistency, that accumulates on nonmoving engine interior surfaces. Generally removable by wiping unless baked to a carbonaceous consistency, its formation is associated with insolubles overloading of the lubricant. and protection of engines operating on ethanol-containing fuels up to E85. to show that the oil has been formulated to improve fuel efficiency.
Oils that satisfy ILSAC GF-5 are superior in performance to those meeting ILSAC GF-4 and earlier and can effectively lubricate engines calling for those standards.
Oils meeting ILSAC GF-5 are typically low High Temperature High Shear. A measure of a fluid’s resistance to flow under conditions resembling highly-loaded journal bearings in fired internal combustion engines, typically 1 million s–1 at 150°C. (≤ 3.5cP) SAE 10W-30, 5W-30, 0W-30, 5W-20, 0W-20 and 0W-16 based on 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. Group II, Group III or Group IV base oils and coupled with API SN PLUS, API SN and resource conserving claim.
