Eni Arnica 68

Heavy-duty hydraulic oil

Eni Arnica 68 is a high-performance anti-wear hydraulic oil specifically developed for modern, industrial, and mobile high-pressure hydraulic systems. Formulated with selected base oils and low-zinc technology, it provides excellent thermal stability and protection against oxidation and aging.

Thanks to its high viscosity index, this oil performs reliably in both cold start conditions and at high operating temperatures. This makes it an excellent choice for marine applications and industrial machinery sensitive to temperature fluctuations.

Applications

• Suitable for high pressure hydraulic systems
• For both outdoor use (marine, mobile systems) and indoor applications
• Works well with sensitive filters up to 3 microns
• Ideal for large temperature fluctuations

Advantages

• Constant performance over a wide temperature range
• Excellent protection against wear of pumps and components
• Very high oxidation stability for longer drain intervals
• Prevents cavitation and aeration thanks to rapid air relaxation
• Excellent water separation and foam control
• Compatible with various metals in hydraulic systems
