HYDRAULIC Oil PLUS is a high performance, fully synthetic, zinc-free, readily biodegradable hydraulic fluid based on a mixture of saturated synthetic esters. A special additive package delivers excellent extreme pressure properties, thermal oxidation resistance, anti-wear and non-foaming control. Because of the high Viscosity Index Hydraulic Oil PLUS provides extremely wide operating temperature range. HYDRAULIC Oil PLUS allows for very long oil-change intervals resulting in cost effectiveness and CO2 emissions reduction.
