Abstract
Green lubricants are gaining increased attention due to the rising demand for environmentally friendly and sustainable solutions. To evaluate their suitability as base oils for lubricants in local automobile and power plant engines, the tribological performance of refined, bleached, and deodorized palm and jojoba oils was assessed and compared. The tests were conducted using a four-ball tester. The bio-based oils’ performance was evaluated under various load and temperature conditions using a tribological testing system. The results showed that unprocessed palm oil outperformed jojoba oil in terms of load-bearing capacity and friction reduction in its raw state. Additionally, palm oil exhibited wear protection performance similar to jojoba oil. With the radical incorporation of suitable anti-wear agents, palm oil can be transformed into a highly effective alternative to mineral oils, offering advantages in terms of tribology, environmental impact, and non-food competition.
