PREMIUM Hydraulic Oil is ultimate performance, fully synthetic, zinc-free, readily biodegradable hydraulic oil based on saturated synthetic esters (top-tier esters of the highest quality). A special additive package delivers outstanding extreme pressure properties, thermal oxidation resistance, anti-wear and non-foaming control. Because of the high Viscosity Index PREMIUM Hydraulic Oil provides extremely wide operating temperature range and greater fluid stability. PREMIUM Hydraulic Oil allows for extremely long oil-change intervals “lifetime fill” resulting in cost effectiveness and CO2 emissions reduction. Produced at viscosity classes 15/22/32/46/68/100.
