🔍 Key Concepts

• How metal wear from bearings or pistons would appear when carried in circulating oil • What metal particles (fine vs large) do to the color or appearance of oil in motion • Why relying on settling to the sump may or may not be realistic in a running compressor

💭 Think About

• If bearings or pistons are physically wearing, what kind of material is getting into the oil, and how would that change what you see through the sight glass? • In a system with oil circulating at pressure and temperature, would heavier particles really settle out where you can’t see them, or would they stay suspended? • Think about what typically causes oil to turn black versus to look shiny or cloudy—what different problems do those colors usually indicate?

✅ Before You Answer

• Be clear on what metal wear particles do to oil appearance under flow and agitation • Distinguish between carbon/soot contamination and metallic contamination in lubricating oil • Ask yourself if any distractor answers describe a non-physical or unlikely condition for oil in an actively operating compressor
