APPLICATIONS:
Eni OSO 15 is a high performance antiwear hydraulic oil, specifically designed to meet the most
rigorous performance requirements of a wide range of hydraulic system and component
manufacturers.
It’s formulated with selected base oils treated with “low zinc” technology ensuring excellent
antiwear, antirust and antioxidant properties. It has an outstanding filterability in service.
Eni OSO 15 is also suitable for other duties in which lubricants of high oxidation stability and
lubrication performance are required, allowing use of a single product with excellent
performance characteristics.
CUSTOMER ADVANTAGES:
• Prolongs oil charge life extending re-lubrication intervals thanks to very high termoossidative stability
• Suitable for hydraulic systems with very thin filters (3 microns)
• Maximizes water removal system efficiency and reduces unscheduled maintenance risk,
thanks to excellent demulsibility
• Protects components reducing downtime casued by unscheduled maintenance, thanks to
oustanding antiwear property
• Helps prevent aeration and cavitation damage in low residence time systems thanks to
rapid air release
• Minimises deposits formation contributing to system cleanliness
