The statement that best describes typical lubricant quality is that new oil is usually clean, but contamination normally doubles each time oil is transferred. This suggests that while new oil generally meets cleanliness standards when it is first produced and packaged, handling and transferring practices can introduce contaminants into the lubricant. Factors such as exposure to air, moisture, and particles during transfer can significantly degrade the quality of the oil.

When new oil is stored and handled properly in its container until it reaches the equipment, it typically starts off at a standard of cleanliness that is acceptable for its use. However, once the oil is transferred—whether from the original container to the machinery or during maintenance processes—it is subjected to risks of contamination, which can lead to a doubling of contamination levels with each transfer. This underscores the importance of implementing proper lubrication practices and cleanliness standards during oil handling and transfer to maintain the quality of lubricants and extend the life of the machinery they are used in.

The other options do not fully capture the realities of lubricant quality in conditions typically found in industrial settings, particularly regarding the cleanliness of new oil and the effects of transfer processes.
