BMW Longlife 12 FE oils are Top Tier lower SAPS1 lubricants. They are designed for use in a limited range of BMW gasoline and light-duty diesel engines as specified by BMW.
BMW Longlife 12 FE oils 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. (≥ 2.9cP) SAE 0W-30 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 IV base oils.
The main physical and chemical requirements for BMW Longlife 12 FE oils are shown below:
|HTHS A measure of a fluid's resistance to flow. A fluid with a higher viscosity flows less easily.||CEC L-36-A-90||cP||≥ 2.9|
|A product of the combustion of metals commonly found in detergents. As a lubricant property, sulfated ash content is a measure of metal content (usually Zinc, Calcium, and Magnesium) and allows formulators to stay within specified limits in order to minimize the negative effects of abrasive ash particles. Sulfated ash is determined by charring the oil, treating the residue with sulfuric acid, and evaporating to dryness, the result being expressed as % by mass.||American Society for Testing and Materials. An organization that develops international standards for industry, including test methods, specifications, and best practices. Many tests that certify a lubricant to a specification are overseen by ASTM. D874||%wt||≤|
|Evaporation loss (NOACK)||CEC L-40-A-93||%||≤|
|Total Base Number||ASTM D2896||mgKOH/g||≥ 6.0|
Note 1 : SAPS refers to Sulphated Metallic deposits formed in the combustion chamber and other engine parts during high-temperature operation., Phosphorus and Sulphur, the levels of which are often restricted in the latest performance specifications.
BMW Longlife 12 FE is usually coupled with European Automobile Manufacturers Association (Association des Constructeurs Européens d'Automobiles). The primary automotive standards organization in the European Union, ACEA defines performance specifications for automotive lubricants. C2-16.
