Polyisobutylene Succinimide (PIBSI)

Polyisobutylene Succinimide (PIBSI) is a premium, ashless dispersant used as a primary additive in engine oils, hydraulic fluids, and transmission fluids. Formulated to keep engine components clean, PIBSI prevents the agglomeration of sludge, varnish, and carbon deposits. By maintaining these contaminants in suspension, it ensures optimal engine performance, prevents filter plugging, and extends oil service life in both gasoline and heavy-duty diesel engines.

Recommended Applications

  • Automotive Lubricants: Used in passenger car motor oils (PCMO) to control sludge and maintain engine cleanliness.
  • Heavy-Duty Diesel Oils: Critical for modern diesel engines to manage soot loading and prevent soot-induced sludge.
  • Hydraulic & Transmission Fluids: Provides essential cleanliness and prevents deposits in sensitive hydraulic valve systems.
  • Marine & Industrial Oils: Effective in circulating oils and specialized marine lubricants to handle water-borne contamination and heavy particulate loads.
