Micropitting (gray staining) is a fatigue failure mode common in hardened steel gears. The 2768 formulation addresses this through a balanced additive chemistry that prevents the "over-etching" sometimes caused by overly aggressive EP additives, while still providing sufficient surface protection.
Based on the format and structure of the code, it's possible that "2768 MK" could be related to: 2768 mk

While PAOs provide the structural backbone, synthetic esters provide polar characteristics essential for lubricity. Esters have an affinity for metal surfaces, forming a tenacious boundary layer. Furthermore, esters act as solvency agents, preventing the formation of varnish and sludge by keeping oxidation products dissolved. While PAOs provide the structural backbone, synthetic esters
This paper analyzes the engineering requirements for extreme pressure (EP) gear oils operating under severe thermal and mechanical loads. It examines the performance profile of advanced polyalphaolefin (PAO) and ester-based formulations, specifically addressing the mechanisms that allow products such as to outperform conventional mineral oils. The discussion focuses on the synergy between synthetic base stocks and advanced additive packages, particularly regarding micropitting resistance, bearing life extension, and energy efficiency through reduced traction coefficients.
