The dropping point is the temperature when the first drop of oil falls from the test cup and reaches the bottom of the test tube under ASTM D 2265. It's a good indicator of grease type in terms of thickener types, such as organic, inorganic or soap/complex soap. As the test method indicates, the dropping point alone has only limited significance with respect to service performance. The operating temperature of a grease product depends on components, base oil, thickener, additives, etc. High-temperature greases are often synthetic-based inorganic or soap/complex soap greases, such as Mobiltemp or Mobilith SHC Series greases.
