The resistance to thinning out by hydrocarbon dilution allows PGS to maintain the proper operating viscosity, extending drain intervals and parts life. This unique blend is specifically additive treated with rust and corrosion inhibitors, oxidation control agents, anti-wear compounds, and hydrogen sulfide inhibitors.
