CHEMPOL 64456 is a purpose-built additive package developed for the formulation of natural gas engine oils. It is designed for use in compressed natural gas (CNG), liquefied natural gas (LNG), and liquefied petroleum gas (LPG) engines across both mobile and stationary platforms.
Its chemistry is structured to meet the operational demands of shuttle buses, stationary power generation systems, and heavy-duty gas engines that experience prolonged thermal exposure and high nitration levels. The package offers effective control over valve recession, bearing corrosion, and oil degradation—all critical factors in long-life gas engine performance.
