Abstract
An oil-conditioning filter, for use with an internal combustion engine, includes a mechanically active filter element and a chemically active filter element. The chemically active filter element has a beneficial oil conditioning agent contained in a plurality of porous additive-dispensing modules. Each of the additive-dispensing modules includes a hollow housing having a plurality of holes formed therein, and a beneficial oil additive disposed within the housing. Optionally, each additive-dispensing module may also include a porous or semi-porous polymeric membrane covering the housing, to control the rate at which the additive material diffuses outwardly therefrom.
