車用引擎潤滑油(俗稱機油),和一般潤滑油組成一樣,由基礎油和添加劑組成,基礎油以礦物油為主,本文以精煉棕櫚油取代礦物油,進行黏度.黏度指數.及磨耗試驗,來探討棕櫚油作為車輛引擎潤滑油之可行性.棕櫚油之黏度接近SAE 黏度分類之SAE 20,與市售機油以一比一混合,黏度便成SAE 30等級,可將黏度指數值由101提高為147.
另外,棕櫚油和SAE 30機油之混合油,經由四球式磨耗試驗在40KG,120℃,1200rpm下,進行一小時之磨耗試驗,結果顯示棕櫚油的添加可減少10%的磨耗量

In general,the lubricants were composed by basestock and additive,and the basestock is usual use mineral oil. This paper examines the viscosity,viscosity index and antiwear properties of palm oil blended lubricants. To study the feasibility of using palm oil as the lubricant of automative engine .
The V.I. of commercial sae 30 engine oil will increase from 101 to 147 via the blend of palm oil and SAE 30.The anti-wear charactisteristics
test in a four-ball tribometer.Under conditions of 40kg,1200rpm,and a test duration of one hour at 120 ℃. The test oil
appear markedly superior to the reference SAE 30 engine oil .The palm oil blended lubricant showed is reduced to 10% scar than
reference oil .
