Abstract

An air filter oil composition is provided for enhancing airflow and filtration of air passing through an air filter. The composition includes a first portion comprising paraffinic oil, a second portion comprising polyalphaolefin (PAO), and a third portion comprising black dye. Applying the air filter oil composition to a cotton air filter material causes tackiness throughout the air filter material, thereby enhancing airflow and filtration of air passing through the air filter. The composition generally is substantially non-reactive, has an excellent oxidation stability, possesses good thermal stability, and retains a suitable viscosity at normal operating temperatures of an automobile engine. In an embodiment, the composition comprises 96.74% paraffinic oil by volume, 3.20% PAO by volume, and 0.06% black dye by volume. A viscosity of the composition at 100 degrees-C ranges between substantially 7.2 and 7.6 centistokes (cSTs).

Claims
