CHEMPOL 4373C is a specially formulated Continuously Variable Transmission (CVT) fluid additive package, developed using extensive vehicle application knowledge and transmission system expertise. It is designed to meet the demanding performance requirements of a broad range of vehicles equipped with push-belt and chain-type CVT systems.
CHEMPOL 4373C enables the formulation of high-quality CVT fluids when blended with suitable Group III base stocks and PMA-based viscosity index improver (CHEMPOL 5403), delivering the critical balance of frictional performance, anti-wear protection, and thermal stability required for smooth, efficient, and long-lasting transmission operation.
