 abstract = {Thermo-oxidative lubricant breakdown leads to varnish formation. Radical process. EPR study of radical intermediates involved in oxidation revealed:•Initiation of breakdown does not require O2 as previously thought.Oil hydrocarbons form radicals on their own. Role of O 2 : trap which promotes radical propagation. Results in O 2 incorporation to form polar breakdown products. Polar products result in varnish formation.2 Strategies to mitigate the risk of lubricant varnishing: 1.Don't allow polar breakdown products to form: • Limit lubricant exposure to O 2 using inert N 2 blanket. 2. Remove any polar breakdown products which do form: • Use resin to remove soluble polar species before they can form varnish. Improve lubricant condition and maintain it even under degrading conditions.},
