Mobilgrease 33, a high-performance BMS3-33 multipurpose airframe grease

Mobilgrease 33 is a high-performance, BMS3-33 multipurpose airframe grease uniquely formulated with a proprietary blend of Polyalphaolefin (PAO) base oils and lithium complex soap. Unlike other commercially available BMS3-33 greases, this unique formulation is ester-free, providing superior performance and hydrolytic stability, excellent resistance to thermal and oxidative degradation, exceptional wear protection in heavy loaded pressure environments, without an offensive odor. Our ester-free blend offers exceptional performance in wet environments — to resist water washout and evaporation loss, protecting the grease from the deteriorating effects of hydrolysis.
