Physico-Chemical Characteristics of Some Commercial Lubricants Sold In Market Around Surulere, Lagos State, Nigeria
Physicochemical analysis was carried out on Ten (10) different brands of motor oil, in which sixÂ (6) were monograde and four (4) multigrade lubricants. The parameters tested were KinematicÂ viscosity, Viscosity Index, Specific gravity, Flash point and Total base number (TBN). The testÂ results obtained were further compared with standard ratings of the Society of AutomobileÂ Engineers (SAE). Analysis of variance (ANOVA) was determined to know if differences exitedÂ among the means of samples properties. It was observed that sample A3 had the lowest TBN ofÂ 4.21mgKOH/g, while A6 had the lowest viscosity index of 87 and did not meet the minimumÂ statutory requirement. Sample A7, A9 and A10 had Flash point values of 218Â°C, 219Â°C& 218Â°CÂ respectively, which were less than the minimum requirement. Sample A2 has the highest meanÂ specific gravity of 0.8981at 150C. Most of the accessed products did not meet the minimumÂ standard requirement.
