What is Additives

• Definition

  Lubricant additives, added with base oil, are chemical compounds to enhance or supplement the performance of lubricants.

  Base Oil + Viscosity Modifier, Detergent & Dispersant, Anti-Oxidant, Anti-wear, Pour Point Depressant, Anti-foamer, Friction Modifier, Corrosion and Rust Inhibitor → Lubricant

  

• Type and Function

  Types and Functions of Additives

  Type	Function
  Viscosity Modifier	Keeping stable viscosity in high or low temperature.
  Detergent & Dispersant	Preventing sediment on the passage of lubricants and inside engine by catching contaminating materials, and decomposing soot.
  Anti-Oxidant	Increasing viscosity and reducing sludge and sediment by inhibiting the chain reaction of oxidization with oxygen, nitrogen, heat etc.
  Anti-wear	Preventing abrasion by friction between metals.
  Pour Point Depressant	Preventing frost of wax by eduction in low temperature.
  Anti-foamer	Preventing and decomposing foam in lubricants.
  Friction Modifier	Improving fuel efficiency by reducing friction.
  Corrosion and Rust Inhibitor	Preventing rust by acidic components arising from condensate moisture and incomplete combustion.
