OZ 2629 – Marine Cylinder Oil Additive Package
High-Performance Additive for TBN 40 and TBN 70 Marine Cylinder Oils

Description:
OZ 2629 is a specially formulated marine cylinder oil additive package developed to meet the stringent performance demands of modern marine engines. It is composed of a balanced blend of high-quality detergents, dispersants, and other functional components to ensure long-lasting protection under the severe operating conditions of slow-speed, crosshead marine diesel engines.

OZ 2629 is designed to deliver superior acid neutralization, thermal and oxidative stability, and exceptional corrosion protection, making it ideal for blending marine cylinder oils with Total Base Numbers (TBN) of 40 or 70. Field use has proven that lubricants formulated with OZ 2629 provide prolonged protection for engine cylinders, significantly extending engine life and reducing maintenance needs.

Key Performance Benefits:

  • Excellent acid neutralization capacity – effective in high-sulfur fuel environments

  • High-temperature detergency – prevents deposit formation under extreme operating conditions

  • Good dispersancy – maintains engine cleanliness and prevents sludge build-up

  • Strong anti-wear protection – extends cylinder and ring life

  • Outstanding oxidation resistance – enhances oil durability

  • Superior anti-corrosion and anti-rust performance – protects against metal surface degradation

Applications:

  • Formulation of TBN 40 and TBN 70 marine cylinder oils

  • Suitable for slow-speed, crosshead marine diesel engines operating under high thermal loads and corrosive conditions

  • Especially recommended for marine vessels burning high-sulfur heavy fuel oil (HFO)
