Which factor should be considered when adjusting lubrication interval?

• A. Operating conditions, load, speed, and environment
• B. Color of the oil
• C. Brand of lubricant only
• D. Time of day

Answer: (A)

Lubrication intervals should be guided by how the equipment actually operates, including the load it carries, the speed it runs at, and the environment it’s in. Heavier loads and higher speeds drive more shear, heat, and oil degradation, while a harsh or dirty environment brings in contaminants that can compromise the lubricant’s film and shorten its effective life. These factors determine how quickly the lubricant loses its protective properties, so the interval must be adjusted based on real operating conditions rather than superficial cues. Color of the oil isn’t a reliable indicator of performance, and the brand of lubricant alone doesn’t account for how the machine is used or the conditions it faces. Time of day has no impact on lubrication performance.
