Which of the following is a benefit of cleaning stored or new lubricants?

Cleaning stored or new lubricants offers several important benefits that enhance the reliability and longevity of machinery. One significant benefit is the improvement of filter lifespan. By ensuring that lubricants are free from contaminants, filters do not have to work as hard to remove particles, thus extending their operational life.

Additionally, cleaning lubricants helps in reducing maintenance costs. When lubricants are clean, the risk of equipment failure due to contamination is minimized, which in turn reduces the need for costly repairs, downtime, and the replacement of lubricants or components.

Furthermore, preventing sediment build-up is crucial. Sediments can lead to wear and tear on machinery, as well as clogs in the lubrication system, which can severely affect performance and reliability. By cleaning lubricants, sediment formation is effectively curtailed, ensuring smoother operation.

Given these benefits—improving filter lifespan, reducing maintenance costs, and preventing sediment build-up—it's clear that cleaning stored or new lubricants provides a comprehensive advantage in maintaining the functionality and efficiency of equipment. Thus, the choice that encompasses all of these benefits is indeed the most appropriate answer.
