APPLICATIONS:
Eni OSO 100 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 100 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 thanks to excellent demulsibility
• Protects components reducing downtime thanks to outstanding antiwear property
• Helps prevent aeration and cavitation damage in low residence time systems thanks to
rapid air release
• Minimizes deposits formation contributing to system cleanliness
