Esterification, the process of making of esters, is generally an exothermic reaction (combining the ingredients produces heat, until the reaction is complete). The application of further heating is to drive off any water that was generated during the reaction, and in some cases done under reduced pressure in order to keep the post reaction temperature low.
Polymerization of the engine oil over time increases the bulk oil's viscosity, which leads to slightly thicker oil films as it ages.
The introduction of fresh oil allows the detergents to strip-off any crud left behind by the aged, oxidized, and polymerized oil.
Any fresh oil added to a machine can only be a plus since the PI package is refreshed.
