VW50800/50900 is a recent addition to the range of active Volkswagen specifications and represents an improvement in fuel economy performance when compared to previous Volkswagen specifications. This is driven by continued pressures on OEMs to improve vehicle fuel efficiency to meet tightening CO2 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. legislation which will come into force in 2021.
VW50800/50900 oils are premium lower SAPS¹ lubricants designed for use in specific high performance gasoline and light duty diesel engines where advanced aftertreatment systems such as Gasoline Particulate Filters (GPFs) or Diesel Particulate Filters (DPFs) are used.
VW50800/50900 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. (≥ 2.6cP and ≤2.9cP) SAE 0W-20 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 VW50800/50900 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||≥ 2.6|
|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||≤ 1.5|
|Sulfur||DIN EN ISO 14596||%wt||Report|
|Evaporation loss (NOACK)||CEC L-40-A-93 (B)||%||< 11|
|Total Base Number||DIN 51369-1||mgKOH/g||≥ 6.0|
VW50800/50900 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. C5.
