| Abstract: | The viscosity of lubricating oils (lubricants) is a very essential component of lubricity in any tribology, regardless of the type of lubrication function and system in question. The lubricants’ viscosity is always needed to be at an optimal level, not too high that it could not be able to penetrate through the contact surface that require lubrication, and not too low that it will easily be squeezed out of the surfaces. In most often than not, lubrication of contact surfaces is carried out at temperatures above the room temperature. However, the temperature at which these lubricants are subjected to greatly affect the viscosity of the lubricants. Before thinking of substituting a non-degradable mineral/petroleum based lubricants with an environmentally friendly vegetable based lubricants, it is essential to ensure that at least they can perform the same way if not better than the existing conventionally used oils in all aspects, in which, viscothermal stability is one of the functional requirements. This is what this study tends to investigate. The aim of this study is to determine and compare the viscothermal stability of Jatropha oil and SAE 40 motor oil. In this study, the viscosities of SAE 40 motor oil and that of Jatropha oil were determined at different temperatures (21, 40, 60, 80, and 100oC) to study the viscosity variation with temperature using a Brookfield Viscometer as per ASTM D 445-79. The viscosity index for the two oil samples was eventually evaluated. The two oil samples showed a down ward trend in the viscosity with increased temperature from 21°C to 100°C, but SAE 40 motor oil shows higher viscosity values especially at lower temperatures but with Jatropha oil displaying a better Viscothermal stability, having a viscosity index of 391, which is higher than that of SAE 40 motor oil which has a value of 245 as calculated according to ASTM D 2270-40 |
