I believe you would call it petroleum. Of course, it's a bit more refined where I come from. A nice large deposit of it kept us going for years in the Horsehead nebula. Unlike Earth-bound fossil fuels these hydrocarbon molecules are created by the fragmentation of giant carbonaceous molecules called polycyclic aromatic hydrocarbons, a waste-product of dying stars.
