Complete documentation

Manufacturer's description

Eni OSO S 68 is an anti-wear hydraulic oil for hydraulic systems prone to deposit formation. It is formulated with selected base oils and ashless additives, which deliver excellent anti-wear, anti-rust and antioxidant properties. It is characterised by a high degree of oxidation stability and very good filterability. Eni OSO S 68 is also recommended for other heavily loaded applications such as plain and rolling bearings, couplings and gears.

Applications

  • Antiwear hydraulic oil for hydraulic systems particularly sensitive to deposit formation; formulated with selected base oils treated with ashless technology for excellent antiwear, anti-rust and antioxidant properties, excellent oxidation stability and outstanding in-service filterability.
  • Can also be used to lubricate other mechanical components such as plain and rolling bearings, joints and unloaded gears.

Performance & benefits

  • Ensures component protection during operation thanks to a robust antiwear additive system
  • Prevents deposit formation thanks to its ashless additives
  • Prolongs oil charge life, extending relubrication intervals, thanks to very high thermo-oxidative stability
  • Suitable for hydraulic systems with very fine filters (3 microns) thanks to excellent filterability
