What data should a lubrication schedule include?

• A. Lubricant type, quantity, interval, point identification, and ambient conditions
• B. Lubricant color and viscosity only
• C. Storage location and color
• D. Replacement cost estimates

Answer: (A)

A lubrication schedule should provide the exact details needed to perform maintenance consistently and correctly: what lubricant to use, how much to apply, how often to service, precisely where to apply it, and under the operating conditions the equipment experiences. The lubricant type ensures the right viscosity and additives for the component, while the quantity prevents both under- and over-lubrication. The interval sets when the next service should occur, supporting reliability and minimizing wear. Point identification tells you the exact bearing, gear, or joint to service, removing guesswork. Ambient or operating conditions matter because temperature and environment affect viscosity, contamination risk, and sealing compatibility, all of which influence both the choice of lubricant and the lubrication frequency.

Color or viscosity alone doesn’t provide enough actionable data for scheduling, and they don’t specify where or when to service. Storage location and color are logistical or cosmetic details, not part of the actionable lubrication plan. Replacement cost estimates are financial considerations, not the operational data needed to perform lubrication correctly.

Having all these elements in the schedule helps ensure consistent application, reduces wear, and extends equipment life.
