Phosphorus in engine oil sample
WebMany sulfur-phosphorus EP additives thermally decompose at 250°C to 275°C and again will readily pass the copper strip corrosion test. Sulfur compounds in solvent-refined base oils, which are also typically sulfides, are even more chemically stable. Both EP additives and base stocks are inactive based on the standard copper corrosion test. WebPhosphorus measurements Phosphorus is measured as one of the metals, but it is not an engine wear metal.
