Abstract

Physicochemical analysis was carried out on Ten (10) different brands of motor oil, in which six (6) were monograde and four (4) multigrade lubricants. The parameters tested were Kinematic viscosity, Viscosity Index, Specific gravity, Flash point and Total base number (TBN). The test results obtained were further compared with standard ratings of the Society of Automobile Engineers (SAE). Analysis of variance (ANOVA) was determined to know if differences exited among the means of samples properties. It was observed that sample A3 had the lowest TBN of 4.21mgKOH/g, while A6 had the lowest viscosity index of 87 and did not meet the minimum statutory requirement. Sample A7, A9 and A10 had Flash point values of 218°C, 219°C& 218°C respectively, which were less than the minimum requirement. Sample A2 has the highest mean specific gravity of 0.8981at 150C. Most of the accessed products did not meet the minimum standard requirement.
