ENI ARNICA – High Viscosity Index Hydraulic Oil

ENI ARNICA oils are petroleum base lubricants specially developed for use in hydraulic systems requiring fluids with extremely high viscosity index and very low pour point for correct operation (ISO-L-HV classification). The oils are formulated to provide stable performance even under severe operating conditions.

Their high viscosity index minimizes viscosity changes caused by temperature variations while ensuring reliable lubrication and smooth hydraulic performance. ENI ARNICA oils are suitable for precision hydraulic systems where consistent viscosity behavior is critical.

Key Features & Performance Benefits

Extremely high viscosity index reducing viscosity variation with temperature
Good anti-wear properties for long hydraulic component life
Excellent thermal and oxidation stability
Strong anti-rust protection for metallic circuit components
High hydrolytic stability minimizing sludge formation
Very good demulsibility for easy water separation
Low pour point for wide temperature range applications
Stable lubrication under heavy-duty operating conditions
