Oxidation process in lubricants produces detrimental byproducts like acids, sludge, and varnish. Antioxidants inhibit this chemical reaction and disrupts the chain reaction leading to oxidation. By preventing the breakdown of oil and the formation of harmful by-products, antioxidants enhance the oxidative stability of the lubricant and its ability to withstand higher temperatures. This, in turn, extends the lubricant’s service life. Additionally, antioxidants also possess corrosion-inhibiting properties, safeguarding metal surfaces from rust and corrosion.
