Vegetable oils, lubricant substitutes

Biodiesel is a mixture of fatty acid methyl esters (FAMEs) which are produced from a broad range of crude oil materials, such as vegetable oil, animal fats, and waste oil, via transesterification of triglycerides with methanol or ethanol. Biodiesel has been regarded as a promising fuel to be able to partly substitute for conventional fossil diesel since it is obtained from renewable sources and for their environmental friendly properties like biodegradability and very low toxicity, lower perticulate emissions and increased lubricity and provides a means to recycle CO2 (Kim Dale, 2005, Ryan et al., 2006).
