The processing of making lubricating oil from crude oil in refineries in Indiana. The lubricating oil is further purified by passing it through a 15 foot Fuller's earth bed in large filters. Animation shows that the filter is charged with fuller's earth. The oil is passed into the filter. The oil percolates through the fuller's earth and becomes lighter in color.
