| Summary: | Mineral oil has been dominated the market as the base oil for engine oil due to its availability, low cost and good performance. However, due to the decomposition issues and emission of toxic gases during its use, it becomes a source of pollution to the environment. This paper evaluates the effects of blending semi synthetic engine oil (SSEO) with palm oil (PO) and palm oil-based trimethylolpropane (TMP) ester on its tribological properties. The aim is to assess the potential of alternative base oil for engine oil which is more environmentally friendly and effective in reducing wear and friction. Consequently, experimental investigations were conducted to analyse the coefficient of friction (COF) and wear scar diameter (WSD) by using four ball tribotester. The blend of palm oil with 2 wt% TMP ester exhibited the lowest COF and WSD of 0.075 and 485.7 µm. Adding 0.5 wt% of nanoglass powder (NG) to the mixture oil consisting of 30 wt% (2 wt% TMP ester and 98 wt% PO) with 70wt% of SSEO, reduce the COF from 0.0609 to 0.057 and WSD from 318.9 to 295.53 µm. Indeed, tribological properties of SSEO improved with the incorporation of palm oil and TMP ester. © 2020 Malaysian Tribology Society (MYTRIBOS). All rights reserved. |
