What is the recommended threshold of water contamination in lubricating oil?

The recommended threshold of water contamination in lubricating oil is typically within the range of 0.02% - 0.075%. This range is considered acceptable to maintain the oil's performance while minimizing the risk of corrosion and degradation of the lubricant. Water contamination can lead to several issues in lubrication systems, such as reduced lubrication effectiveness, increased wear, and the formation of emulsions, which can compromise the reliability and life of machinery.

If water content exceeds this recommended threshold, there may be a higher likelihood of significant operational problems. Regular monitoring is essential to ensure that water levels stay within the safe range to maintain optimal operating conditions and prolong the life of the machinery.
