Bio-based lubricant has long known for its superior lubricity. Through the process called transesterification the vegetable oil and animal fats can be transformed into lubricant or polyol ester. For twostroke petrol lubrication, mineral-based lubricant is still widely used. This gap must be filled so that the twostroke engine could be lubricated with the same highquality bio-based lubricant as the four-stroke, leads to better fuel economy and cleaner emission. In this paper a polyol ester called Trimethylol Propane Trioleate (TMP TO) blend has been tested for wear performance. Result shows COF reduction of 7.3% as well as 47.8% less wear scar diameter compares to mineral-based lubricant.
