A durable magnetorheological fluid for use in a vibration dampening device is described. The MR fluid includes magnetizable particles having a particle size less than about 25 microns, a carrier fluid, a thixotropic agent, and a lubricative additive. The carrier fluid includes a polyalphaolefin and a plasticizer. The lubricative additive has a particle size equal to or less than 10 microns such that the ability of the additive to lubricate the magnetizable particles is optimized. The lubricative additive includes at least one of polytetrafluoroethylene, graphite, and molybdenum disulfide.
