Why is avoiding cross-contamination of lubricants crucial?

Avoiding cross-contamination of lubricants is critical primarily because it prevents reduced lubricant effectiveness. When different lubricants mix, it can alter the properties and performance characteristics of the resulting fluid. Each lubricant is formulated with specific additives designed for particular applications, and contamination can lead to the neutralization of these additives or the introduction of harmful substances. This degradation can result in insufficient lubrication, increased wear on machinery components, and ultimately, equipment failure.

For instance, mixing a lubricant that has additives for extreme pressure with one that is formulated for high-temperature environments might lead to a reduction in the overall performance of the mixture, compromising its ability to protect against wear, corrosion, and thermal degradation. Ensuring the integrity of each lubricant helps maintain operational efficiency and extend the lifespan of machinery.
