A method for controlling formation and dissipation of at least one oligomeric or polymeric aminic antioxidant in a lubricating oil, during operation of an engine or other mechanical component lubricated with the lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one oligomeric or polymeric aminic antioxidant, as a minor component. The at least one oligomeric or polymeric aminic antioxidant is formed over time in situ from at least one monomeric aminic antioxidant during operation of the engine or other mechanical component. The at least one oligomeric or polymeric aminic antioxidant is dissipated over time in the lubricating oil during operation of the engine or other mechanical component. The at least one monomeric aminic antioxidant is present in an amount from greater than 2 to 10 wt.% of the lubricating oil.
