What is a recommended remedy when lubrication signs indicate the wrong oil type is used?

• A. Increase the oil quantity
• B. Adjust the FRL or oil type
• C. Ignore the lubrication signs and proceed
• D. Change the lubrication at the next maintenance cycle

Answer: (B)

Lubrication in pneumatic systems relies on using the correct oil type and delivering it at the right rate. When signs show the oil being used is not the one specified, the fix is to correct the lubrication setup by adjusting the FRL to use the proper oil or by switching to the correct oil type. The lubricator injects oil into the airstream at a controlled drip rate, and using the wrong oil can cause poor film formation, deposits, seal swelling, and accelerated wear. Simply increasing the amount of oil won’t solve the mismatch and can lead to over-lubrication or contamination. The right approach is to replace with the correct lubricant, set the lubricator to the recommended drip rate, and flush or clean the lines if needed. After changes, verify that lubrication signs return to normal and that the system operates smoothly.
