GER fluids are improved by the addition of a polar molecule additive. By addition of a polar molecule additive, yield stresses under electric field are improved by over 50% while the current density is reduced to less than a quarter of the original GER. The reversible response time still remains the same, and the sedimentation stability is greatly enhanced. The zero field viscosity of the modified GER fluid remains the same as that of the original GER fluid without the additive. The improved GER characteristics improve general functionality as an electrical-mechanical interface, attendant with applications to car clutches, fluid brakes, and vehicle shock absorbers.

A lubricant composition which contains a lubricant base oil, (A1) a metal salicylate and (B) a molybdenum-based friction regulator, and which is characterized in that: the amount of the component (B) is 500 to 1,500 ppm by mass in terms of the molybdenum concentration [B] in the lubricant composition; the component (A1) is calcium salicylate, magnesium salicylate or a combination thereof; the calcium concentration [Ca] based on the calcium salicylate in the lubricant composition is 0 to 1,800 ppm by mass; the magnesium concentration [Mg] based on the magnesium salicylate in the lubricant composition is 0 to 1,800 ppm by mass; and the total of the calcium concentration [Ca] and the magnesium concentration [Mg] is 200 to 3,000 ppm by mass. 1. A lubricant composition comprising:a lubricant base oil;(A1) a metal salicylate; and(B) a molybdenum-based friction modifier,whereinthe amount of component (B) is in a range of 500 to 1,500 ppm by weight in terms of a concentration [B] in ppm by weight of molybdenum in the lubricant composition,component (A1) is any one of calcium salicylate, magnesium salicylate, and a combination thereof,the amount of calcium salicylate is 0 to 1,800 ppm by weight in terms of a concentration [Ca] in ppm by weight of calcium derived from calcium salicylate in the lubricant composition,the amount of magnesium salicylate is 0 to 1,800 ppm by weight in terms of a concentration [Mg] in ppm by weight of magnesium derived from magnesium salicylate in the lubricant composition, anda total of [Ca] and [Mg] is in a range of 200 to 3,000 ppm by weight.2. The lubricant composition according to claim 1 , which further comprises a metallic detergent other than component (A1) as a metallic detergent (A) claim 1 ,wherein the weight of component (A1) based on the total weight of the metallic detergent (A) is in a range ...
