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. WebAug 9, 2024 · in an oil analysis, because this is where we’ll see signs of mechanical problems developing in the engine. The other elements (calcium, phosphorus, and zinc) are additives, and we’ll get into more detail about those later. These averages aren’t separated by oil type, because typically, we expect each engine to produce similar levels of wear,
