Plutus GX industrial Gear & Bearing Oil is a premium performance, fully synthetic industrial oil based on high performance additives and polyalphaolefin (PAO) and ester technology that enhance oxidation stability, improve foam control, maintain superior stability in the presence of water, and provide protection against rust, corrosion, and wear. Synthetic base oils provide longer oil life over conventional mineral oils. Plutus GX industrial Gear & Bearing Oil has a naturally high viscosity index (VI) compared to mineral oils, providing lower viscosity at lower temperatures and higher viscosity at higher temperatures. This high VI allows the oil to flow at cold temperatures so equipment will start. It also means viscosity will be maintained at high temperatures to provide wear protection.
