ABSTRACT
This study importance is to determine the relation of motor engine oil with changes in temperature and its effects on fuel system. Although other factors that affect viscosity of motor engine oil are mentioned, we have dwelt more on the factor of temperature, and we have taken into consideration that the temperature can be affected both by the environment and the engine system. This is a localized study of the monograde, multigrade and local oil of Ijebu-ode, Ago-Iwoye and environs.
In this study we have adopted the “Falling ball” method. Temperature readings were done by thermometers and timing was done using a stopwatch. The oils were placed in graduated cylinders and balls were dropped in the cylinder. This was done three times at 20°C, 0°C, and 70°C. The different variables that were used to solve for viscosity are density, volume, and velocity.
Results shows that as the temperature increases to higher degree, the change in the kinematic viscosity becomes very small especially for local oils A, B and C. These oils have been most used for generators and motorcycles, this research further shows that this is in fact a reason for high rate of malfunction of motor engines in these areas as Nigeria is already a hot region. The SAE 20W-50 was found to be most adjustable to temperature. The implication of this study is to give an informed opinion on the use of proper motor oil as indicated by manufacturer with regards to temperature and confirm the integrity of monograde, multigrade and local oils in Ijebu-Ode, Ago-Iwoye and Environs.
