In this research, evaluation and optimization of poly- aromatic cationic surfactant as modifier for base mineral oil. Different weight percent from this modifier was added to base mineral oil and assessed. Physicochemical properties mineral base oil and blended oil were carried out. The rheological behaviors of base mineral oil with and without modifier were investigated at different temperatures using Programmable Rheometer LADV-III Ultra-System. Yield stress and dynamic viscosity for these blended oils were determined. Optimization and modeling of the obtained data concerning dynamic viscosity was studied which the predicting of these data with different temperatures. It was found that the rheological behavior of these oils show Newtonian flow. The results revealed that the rheological behavior and pour point of base oil with and without poly-aromatic cationic surfactant depend on a large extant on the contents of the components in the base oil. It was concluded that the poly-aromatic cationic surfactant can be used as rheological and pour point modifier to such base mineral oil. The predicted of viscosity mineral base oil blank or with additive poly-aromatic cationic surfactant at temperature 130, 160 and 190oC using Trend line modelingwhich as blended base oil samples show the poly- aromatic cationic surfactant is suitable as rheological modifier.
