VW50500/50501 oils are Top Tier lower SAPS¹ lubricants designed for use in light duty direct injection diesel engines with unit injectors. In Europe, VW50400/50700 oils may also be used in many vehicle models where Volkswagen 50500 or 50501 is specified.
VW50500/50501 oils are typically high 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 5W-30 or 5W-40 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 III base oils.
The main physical and chemical requirements for VW50500/50501 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||≥ 3.5|
|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.||DIN 51575||%wt||≤ 0.80|
|Phosphorus||DIN 51399-1||%wt||≥ 0.07|
|Evaporation loss (NOACK)||CEC L-40-A-93||%||< 13|
|Total Base Number||DIN 51639-1||mgKOH/g||≥ 7.0|
Note 1: SAPS refers to Sulphated Metallic deposits formed in the combustion chamber and other engine parts during high-temperature operation., Phosphorus and Sulfur, the levels of which are often restricted in the latest performance specifications.
VW50500/50501 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. C3, MB229.51, MB229.52, MB29.31, BMW Longlife-04, GM dexos2™ and Porsche A40 (5W-40 only).
