Dispersant additives (GL 1951) are an ash less succinimide lubricating dispersant oil additive with extended thermal stability. It generally finds application with corrosion and oxidation inhibitors and alkaline detergents in gasoline and diesel engine oils. It provides excellent low temperature sludge and varnish control in gasoline engines. The dispersant additive is also effective dispersancy for deposit control in both medium-speed and high temperature super-charged diesel engines.

Formulation for the dispersant additive recommended is 0.5% to 5.0% by weight and by volume too. The additive is used in combination with detergent and inhibitor chemicals in cranckase engine oils for improving lubricant dispersancy properties for engines operating under low and high temperature conditions.

Applications for the Dispersant Additive:

• Lubricant and fuel additives
• Emulsifiers
• It diffuses 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 ash less dispersant additive and have low chlorine content
• Typical properties

Viscosity index improver (GL 3015), is a cost-effective OCP viscosity modifier meets global needs efficiently. It is a non-dispersant olefin co-polymer viscosity modifier which is specially engineered for providing low-temperature performance while maintaining excellent film strength and engine test performance.

Viscosity index improver (GL 3015), an oil concentrate of an olefinic copolymer is primarily used as a viscosity index improver for crankcase lubricants particularly where excellent shear stability is required.

There is possibility of some loss in viscosity and in viscosity index because of the shear forces encountered in engine operation. It applies to all viscosity index improver. In this respect, our range performs excellently as evidenced by an average viscosity loss of 14 % at 100° C for SAE 15W-50 crankcase oils in over the road service.
