Antioxidants, anti-rust and anti-wear

Eni produces components designed to prolong oil life (antioxidants) and for engine protection (anti-wear and anti-rust), developed in Eni’s R&D labs and now available for sale.
  • Eni MX 3102


  • Eni MX 3104


  • Eni MX 3171




Eni produces detergents based on neutral and overbased calcium sulphate for automotive, marine and industrial applications. Eni detergents control the formation of deposits on hot engine parts and neutralise combustion acids to limit corrosion.

  • Eni MX 3280

    (Neutral Calcium  Sulfonate)

  • Eni MX 3245

    (Overbased Calcium  Sulfonate - TBN 300)

  • Eni MX 3240

    (Overbased Calcium  Sulfonate - TBN 400)



The colder parts of the engine can produce sludge that accumulate in the oil impeding the flow to the most critical points of the lubrication circuit. Eni’s chlorine-free dispersants suspend such impurities, extending the effectiveness and life of the oil.

  • MX 3309

    (Dispersant used in chemical solvent for industrial applications)

  • MX 3316

    (Dispersant tipically used in crankcase engine lubricants)

  • Eni MX 3318

    (Dispersant recommended for 2 strokes engine lubricants applications)

  • Eni MX 3323

    (Dispersant typically used in crankcase engine lubricants)


Viscosity modifiers

Eni produces olefin copolymers (OCP) characterised by high levels of stability and thermo-oxidative properties that ensure the preservation of lubricating oil film on moving metal surfaces under different operating conditions and varying temperature.

  • Eni MX 4106

    (V.I.I OCP type - high ethylene content)

  • Eni MX 4050

    (Olefin Copolymer Rubber (OCP) – low ethylene content)

  • Eni MX 4006

    (Olefin Copolymer Rubber (OCP) – high ethylene content)


Pour Point Depressants

  • Eni MX 4330

    (PPD miscible with OCP Viscosity Index Improvers)

  • Eni MX 4332

    (PPD recommended for transmission oils and in Group II- III base-stocks)

  • Eni MX 4333

    (PPD High performance)

  • Eni MX 4346

    (Dilute version of Eni MX 4333)
