Gas Compressor Oils (GCO) are a premium quality lubricant formulated with specific base oils, combined with a field-proven additive system containing oxidation and corrosion inhibitors, antifoam and anti-wear agents. These products are fortified with additives to provide protection during high load and temperature conditions. Gas Compressor Oils pass industry rust and corrosion protection tests. Oxidation protection will prevent high temperature thermal degradation. This low volatility and low deposit formulation will provide overall protection while minimizing cylinder valve deposit.
