This paper presents the experimental results of normal lubricant, additives added lubricants and waste vegetable oil (WVO) contaminated bio-lubricants to evaluate the tribological properties such that friction and wear characteristics. The test was conducted using a four-ball tribotester with standard test method IP-239. The balls used in four-ball tribotester were based on carbon-chromium steel ball bearings. To evaluate friction and wear characteristics, coefficient of friction (μ), wear scar diameter (WSD), flash temperature parameter (FTP), viscosity index (VI) and total acid number (TAN) were investigated. Each test was conducted for five different loads from 50 kg to 90 kg at an interval of 10 kg. The lubricant was contaminated with WVO from 1% to 5%. The normal lubricant (as sample A) was used for comparison purposes. The test results showed that WVO contaminated lubricants with suitable anti-wear additive (amine phosphate) can reduce friction and wear coefficient substantially. The objective of this investigation is to develop a new lubricant based on waste palm oil (such as WVO).
