250WT Performance Gear petroleum based gear oil offers unsurpassed performance and protection. Ultra-pure, high quality base oils and thickeners resist shearing, mechanical breakdown and viscosity loss of the oil. High viscosity index (VI) formula offers consistent film thickness and performance over a greater operating temperature range. Technologically advanced formula delivers superior anti-wear and extreme pressure protection from peak loads and elevated temperatures. Surface active chemistry delivers ultra-high film adhesion on gear faces, enabling higher load carrying capability and protecting critical gear interface areas and contact points. Fully formulated additive system contains anti-foam, rust, corrosion and oxidation protection for high-stress conditions.
