MOBIL CENTAUR XHP 461

MOBIL CENTAUR XHP 461 greases are a premium family of greases formulated with advanced calcium sulfonate thickener technology. The calcium sulfonate thickener carries both inherent rust protection and extreme pressure(EP) properties. Compared to conventional soap-based thickeners (i.e. lithium, aluminum, calcium soaps), the calcium sulfonate thickener used in MOBIL CENTAUR XHP 461 excels in water-saturated environments, providing rust protection between long re-lubrication intervals. The inherent EP properties exhibit great stability in the presence of water, allowing a balance between wear protection and resistance to corrosion.
