Physico-Chemical properties of Polyol Ester-Commercial Motorbike Oil Blends

Abstract
The objective of this study is to investigate the effects of blending a bio-lubricant, specifically Pentaerythritol ester, with commercial motor oil and dispersing the blends with graphene nanoplatelets. The research entailed the combination of commercially available motor oil with Pentaerythritol (PE) ester obtained from Calophylluminophyllum. The focus is on analyzing the changes in Physico - chemical properties and optimization of best blending ratio. Optimization of the synthesis of Pentaerythritol ester (PE ester) was done with theaim of attaining a complete conversion to long-chain tetra-esters. Furthermore, significant emphasis was placed on the meticulous formulation of the bio-lubricant to mitigate the risk of any potential deterioration in its physicochemical properties upon its incorporation with conventional oil and graphene nanoplatelets. The blending was conducted using proportions of 10%, 15 %, 20%, 25 % and 30 %. The biolubricant – motor oil blends have optimum perfroamcenup to a blending percentage of 20% beyond which a deterioration occurred.
