Abstract

The need for development of new green lubricant is in the limelight of researchers today. This is due to the fact that, the existing mineral based lubricants are of non-renewable sources and prone to environmental issues. This paper reports the physical property improvement of canola oil and corn oil with the addition of Zinc Dialkyldithiophosphate (ZDDP) as anti-wear agent. Samples with addition of 0wt%, 2 wt% and 5 wt% ZDDP were prepared and tested using RDE-AES spectrometer and a heated viscometer. The samples were then characterized using a pin-on-disc tribometer. Corn oil has a lower kinematic viscosity value compared to canola oil and gives a lower kinematic viscosity value of 36.3 cSt with the addition of 2 wt% ZDDP. The addition of 2 wt% ZDDP in corn oil and canola oil proves to lower the coefficient of friction for both type of oil. The results showed that it is feasible to continue the study on addition of ZDDP in vegetable based oil for substitution to mineral based lubricant oil.
