Although there have been some achievements in bio-lubricants industry, further
improvements are inevitable and are already being recorded with an increasing number of studies directed toward such areas. Firstly, new extraction method should be
developed for large scale production in order to produce castor oil with high quality
effectively. Secondly, lower power-consuming and more efficient modification methods are needed to achieve a better performance of bio-lubricants [13, 14]. And more
and more bio-lubricants should be developed to meet various lubrication demands
[17]. The cost of modification should also be decreased. Thirdly, additives which
can change the chemical and physical properties of bio-lubricants may also have
unknown negative effects on bio-lubricants such as a drop in viscosity or a decrease
in biodegradability [5, 15, 35]. Hence, development of high-performance, multifunctional, and environmental friendly additives with less side effects will become
research hotspot. Additionally, further systematic research of interactions between
bio-lubricants and additives should be conducted. Bio-based high-performance green
lubricants are good for energy-saving and emission-reducing. By accelerating the
application of high-performance green lubricants, improving power, saving fuel,
reducing emissions, and preventing gray skies can be achieved.
