Its function goes far beyond simple lubrication\u2014it\u2019s essential for cooling, sealing, anti-wear protection, and rust prevention. One of the most vital characteristics of high-quality compressor oil is its <strong>oxidation stability<\/strong>, which directly affects compressor longevity and safety.<\/p>\n\n\n\n<p>This guide explains the classifications of air compressor oil, its performance criteria, and why oxidation stability is crucial.
