Technical Abstract: Synthetic lubricant base oils offer improved stability and performance characteristics over refined petroleum oils, but at a price. Most of the biodegradable synthetic oils are chemical esters that offer superior thermal and oxidative stability [8.9]. Prices for these niche products are higher than vegetable oils (VOs) and significantly higher than petroleum-based lubricants. Synthetic oils are partly derived from petroleum products and therefore are dependent on petroleum crude oils. VO-based lubricants cannot replace all synthetic and petroleum-based lubricants, but they play an important role among the alternate energy sources and contribute to the goal of energy independence and security. Although the cost of VO-based lubricants is higher than conventional mineral oil-based lubricants, still environmental advantages in short, medium, and long range can balance the difference in cost.
