Royal Purple HPM Gear Lube is formulated to maximize performance and provide Synthetic DefenseTM for marine lower gear units. Its cushioning molecules absorb gear impact to dramatically minimize wear. HPM Gear Lube also significantly reduces friction, which lowers gear unit temperatures, extends equipment life and improves fuel efficiency.
HPM Gear Lube uses Royal Purple's advanced, proprietary Synerlec® additive technology for maximum water separation and protection from corrosion. It is recommended for equipment requiring an API Service GL-5 or GL-4 fluid.
