The Shandong Oilman

(Beijing) -- It's oil with an extra something, but there's nothing virgin-like about it. Pumped from sewers outside of restaurants, or pressed from trash, the oil is born from waste holes both human and mechanical.

Known as "gutter oil" in China, it's commonly used at greasy spoon restaurants and canteens, many of which purchased the cheap oil processed by businessmen like Liu Liguo.
