Question

All the lubricating oil, in normal course, should be filtered approximately every minute.

(a) True

(b) False

I had been asked this question during an online interview.

The above asked question is from Classification of Lubricating System in section Engine Friction and Lubrication of IC Engine

Answer 1

The correct answer is:

(b) False

Lubricating oil is typically filtered at intervals based on the engine's design, but not necessarily every minute. The filtration rate depends on the engine's operating conditions, the filtration system, and the oil's condition. While oil filtration is essential for maintaining engine performance and reducing contaminants, it does not occur every minute in all systems.
