MK-665 Core Advantages

  1. High-Stability OCP Viscosity Index Improver

    Modified ethylene-propylene copolymer with enhanced shear stability for high-quality multi-grade engine oils.

  2. Improved Shear Resistance

    Lower SSI (shear stability index) delivers better viscosity retention compared to conventional OCP products.

  3. Efficient Thickening Performance

    Provides strong thickening power and excellent viscosity index improvement for optimal viscosity-temperature behavior.

  4. High Thermal & Oxidation Stability

    Excellent stability at high operating temperatures to resist degradation and extend oil life.

  5. For Premium Engine Oil Formulations

    Designed for high-performance multi-grade gasoline and diesel engine oils requiring improved shear stability.
