Inorganic Metal as Additives in SAE 10W-30 Malaysian Automotive Engine Oils
Azmi Roslan, Ahmmed S. Ibrahem and Abdul Hadi

This study presents and discuss the rheological behavior and heat capacity of inorganics metal (Nickel (II) Nitrate Hexahydrate, Titanium (IV) oxide, cobalt chloride, copper, cadmium nitrate, arsenic oxide and ferum (II) Nitrate) as additives in Malaysian engine oil (P-1). They are uniformly dispersed in oil P1. Two different samples were prepared including one sample used as reference oil. Rheological test were performed using rotational viscometer under constant shear rate of 600 sec-1 and temperature settings starting from 40-100°C. The performance of samples was determined by measuring area under the curve for each of samples graph. The sample that exhibits the largest area under the curve represented the best performance. Heat capacity was determined using bomb calorimeter in adiabatic mode of operation. The study led to following conclusions; all compounds appended in the samples exhibited shear stress, viscosity-temperature relationships, time and heat capacity enhancement compared to reference oil. The results also found that the dissolution of 0.3-0.4 ppm of copper, 0.1 ppm cadmium nitrate, 0.1 ppm arsenic oxide and 0.04-0.05 ppm of ferum (II) Nitrate (Test 1) had the best viscosity-temperature relationships, exhibiting higher value of area under the curve. Furthermore, P1-T1 also had shown significantly improve in heat capacity of oil P1. An additional of 0.15-0.17 ppm of Nickel (II) Hexahydrate, 0.03-0.04 ppm titanium (IV) oxide and 1.3-1.4 ppm of cobalt chloride to the test 1 (test 2), also offering an improvement to the viscosity-temperature relationships and heat capacity for P1. However, results for P1-T1 better than P1-T2 in term of viscosity-temperature relationships and heat capacity.
