For lubricating valve stems and position rods, what is the recommended practice?

Use large quantities of oil
Use practically no oil at all
Employ oil with additives
Only apply oil once a month

The correct answer is: Use practically no oil at all

The recommended practice for lubricating valve stems and position rods focuses on avoiding excess lubrication to prevent potential issues. Using practically no oil ensures that these components do not become gunky as a result of over-lubrication. Excessive oil can attract dirt and contaminants, leading to operational issues such as corrosion or jamming. Moreover, the application of minimal oil encourages effective lubrication without the risk of compromising the function of the valve stems and position rods. These components require just enough lubricant to reduce wear and tear, without emulating the performance drop associated with using too much. Hence, employing a conservative approach to lubrication is vital for maintaining operational efficiency while ensuring the longevity of the equipment.
