Magnetorheological (MR) fluids is synthesized using micron-sized electrolytic carbonyl iron (CI) particles and vacuum grease as additive and their rheological behaviours were investigated in terms of particle alignment by controlling magnetic field, also the effect of surfactant Triton X100 was investigated. The overall rheological characteristics and sedimentation characteristics of the synthesised samples of MR fluids were compared with Lord 132DR MR fluid using rotational Rheometer which has magnetic cell. It was establish that combination of electrolytic CI powder with vacuum grease and Triton X-100 improves the stability of the fluid by reducing sedimentation
