True or False: Dust particles from the air can harm the oil.

The assertion that dust particles from the air can harm the oil is not accurate. In general, while contaminants can impact oil, the presence of dust particles alone is not typically considered harmful. Oil is used in various mechanical systems where it serves to lubricate and protect moving parts. It is designed to hold up against certain external contaminants to a degree.

When oil becomes contaminated with excessive amounts of foreign particles, or when other factors such as moisture or chemical deterioration are involved, problems can arise; however, this is a separate consideration. In normal operating conditions, trace amounts of dust or airborne particles do not pose a significant risk to the oil's performance or integrity.

In contrast, other choices may imply specific conditions under which dust could harm oil, but typical everyday exposure to air does not produce the level of contamination needed to be detrimental to oil's function. The focus is thus on the inherent resilience of oil against minor environmental factors.
