Viscosity management poses a significant hurdle in high-temperature environments. Lubricants must maintain an optimal viscosity to provide adequate film thickness and protect moving parts. However, as temperatures increase, most lubricants experience a substantial decrease in viscosity, potentially leading to metal-to-metal contact and accelerated wear.

The volatility of lubricant components at high temperatures is another concern. Volatile compounds can evaporate, leading to oil consumption, increased emissions, and changes in the lubricant's composition. This not only affects the lubricant's performance but can also impact environmental compliance and safety standards.

Seal compatibility becomes more challenging at elevated temperatures. Many conventional seals and gaskets may degrade or fail under extreme heat, leading to leaks and potential system failures. Developing lubricant formulations that are compatible with high-temperature sealing materials is crucial for maintaining system integrity.

The presence of contaminants, such as water or fuel, can exacerbate high-temperature lubrication issues. These contaminants can accelerate oxidation, promote the formation of acids, and contribute to the breakdown of the lubricant. Effective filtration and contamination control become even more critical in high-temperature applications.

Lastly, the development of lubricants capable of withstanding extreme temperatures while maintaining their protective properties is an ongoing challenge. This includes the need for advanced additive technologies that can remain stable and effective under severe thermal stress, as well as base oils that can resist breakdown at high temperatures.
