ABSTRACT
This research project was conducted to determine the viscosity of some selected engine oil samples. The engine oil samples were bought from an Auto Shop in Ikot Ekpene (Main town). The results obtained from this research work using Stoke’s law method and within the limit of experimental error shows variable viscosity where the result was found to be 5.0551kg/m/s for Masters oil, 2.6697kg/m/s for Mega, 2.4488kg/m/s for Mobil Oil, 2.3731kg/m/s for Tonimas and 2.3286kg/m/s for Climax oil, respectively. The observation shows that Master’s Oil has the highest viscosity value. Therefore, within the limit of experimental error, Master’s oil is recommended as the best oil.
