Ultra-Performance Grease (UPG) is a high performance, multi-service, aluminum-complex, synthetic grease which significantly increases bearing life and equipment reliability. It also makes bearings run smoother, cooler and quieter. UPG satisfies a wide range of grease requirements from the lubrication of bearings to U-joints and general purpose use. It has outstanding extreme pressure capabilities and excellent water resistance to both emulsion and washout. UPG is stable at high temperatures. It also has excellent oxidation resistance for extended service life and to provide a margin of safety between lubrication intervals. When the China Star Bullet Train was having heat problems keeping them from achieving optimal speed, they evaluated 26 of the best lubricants available. After careful testing, senior engineers selected Royal Purple’s Ultra-Performance Grease. Not only did Ultra-Performance Grease help them resolve their heat problems, it also, enabled them to set a new land-speed record for bullet trains. UPG is made using a superior blend of synthetic base oils plus Royal Purple’s unique, proprietary, non-corrosive Synerlec additive technology.
