Polyisobutylene Mono‑Succinimide Ashless Dispersant

High-TBN, Chlorine-Free Ashless Dispersant for Marine & Automotive Engine Oils

Polyisobutylene mono‑succinimide is a widely used ashless dispersant for gasoline engine oil and diesel engine oil. It delivers reliable low‑temperature dispersancy and high‑temperature soot solubilization performance, chlorine‑free, with good compatibility with ZDDP and metallic detergents.

Key Features & Compatibility:

· Excellent Soot Dispersancy: Effectively suspends high-temperature soot to prevent engine sludge and deposits.
· Chlorine-Free & Ashless: Environmentally friendly formulation, minimizing wear and extending engine life.
· Outstanding Low-Temp Performance: Ensures reliable oil flow and cold-start protection in harsh winter conditions.
· High Compatibility with ZDDP: Perfectly compatible with anti-wear agents without negative interactions.
· Synergistic with Detergents: Works seamlessly with metallic detergents to boost overall lubricant performance.
