PIBSI Dispersant / Emulsifier is a ashless succinimide lubricating oil additive with extended thermal stability. It is generally used with alkaline detergents, corrosion and oxidation inhibitors, in gasoline and diesel engine oils. This additive provides excellent low temperature sludge and varnish control in gasoline engines and effective dispersancy for deposit control in both medium-speed and high temperature super-charged diesel engines.

It is also used extensively in the explosive industry for its emulsification properties.

in crank case engine oils, in combination with detergent and inhibitor chemicals to improve lubricant dispersancy properties for engines operating under low and high temperature conditions.


  • Lubricant and fuel additives
  • Emulsifiers
  • It diffuse sludge, carbon, soot, oxidation products, and other deposit precursors in engine oils. The result is reduced deposit formation, less oil oxidation, and less viscosity increase.
  • An ashless dispersant additive with low chlorine content.
