NOVELTY - Lithium complex hybrid grease comprises (i) 7-70 wt.% ester or an ester mixture including trimellitic acid esters which have 6-18C, preferably 8-14C linear or branched alkyl groups as alkoxy groups, where the alkoxy group is same or different, pyromellitic acid ester, hydrogenated or unhydrogenated dimer acid and estolides, (ii) 0.5-20 wt.% non-hydrogenated, hydrogenated or fully hydrogenated polyisobutylene or mixtures, (iii) 1-18 wt.% lithium complex soaps and (iv) 5-70 wt.% perfluoropolyether. USE - The lithium complex hybrid grease is useful for lubrication of components, preferably roller bearings, slide bearings, transport and control chains in vehicle technology, rail vehicles in conveyor technology, film stretching system, corrugated cardboard system, roller bearing, fan bearing, bearing of traction motors, bevel and spur gears, springs, screws and compressors, pneumatic components, fittings, continuous casting plant, open gear rings in rotary kilns, tube mills, drums, mixers and machine components in system with occasional and unintended contact with food (claimed). ADVANTAGE - The lithium complex hybrid grease has sufficient oil separation and low hardening even at high temperature. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) method for lubrication or greasing of components, preferably roller bearings, slide bearings, transport and control chains in vehicle technology and in rail vehicles, comprising applying the lubricant composition to the surface of the component; and (2) method for reducing the hardening of lubricating greases at 200 degrees C and reducing the oil separation of lubricating greases, comprising applying the lubricant composition to the surface of the component.
