The mineral oil based super clean hydraulic fluid features an oxidation inhibitor and a non-zinc anti-wear additive. This hydraulic fluid is dyed red for identification and leak detection purposes. It may be used in hydraulic systems where very low temperature flow properties are desired, synthetic rubber seals are in use, and super clean solid particle contaminant standards are required. This hydraulic fluid is the GM approved fluid for use on 2010+ SRX, CTS, Equinox and Terrain lift-gates. It is not recommended for systems using natural rubber seals.
