## Abstract

An apparatus and a system is provided that may be utilized to determine oil migration and oil displacement from a pre-oiled air filter. The present invention may also be utilized to determine if oil is displaced from the air filter onto a portion of the apparatus for visualization to a user. The present invention utilizes a demonstration apparatus having a system for forcing air through the oil subjected air filter thereby attempting to force displacement of the oil from the air filter. The apparatus utilizes a blowing means whereby the oil infused air filter is subject to higher than normal air flow and whereby the apparatus has a deflection portion whereby if oil is displaced from the air filter, it is deflected onto the deflection portion where it would be physically viewable to an observer present in the vicinity of the apparatus.

## Claims

### Claim 1

A system for determining displacement from a filtration media, the system comprising:
a container having at least an opening thereon for accepting an air filtration media within the opening;
a blower for directing air through the air filtration media; and
an extension portion positioned above the air filtration media wherein the extension is shaped into a wedge and is in close proximity to the air filtration media.

### Claim 2

A system for determining displacement from a filtration media, the system comprising:
a container having at least an opening thereon for accepting an air filtration media within the opening;
a blower for directing air through the air filtration media wherein the blower pushes air through the air filtration media at a rate greater than two times the normal operating air flow of the air filtration media's normal vehicle operating air velocities; and
an extension portion positioned above the air filtration media.
