The oil produced from those sources is coming from recent raw materials to animal to fuel conversions, so shouldn't be adding to our net atmospheric CO2 load either.
On June 25, 1921, Friedrich Bergius - a German - liquefied coal into oil in Stuttgart.
Beginning with brown coal (lignite) he ground it into a fine powder and placed into a high pressure reactor with hydrogen gas at high temperature and pressure. The Standard Oil (NJ) Company developed this into a commercially viable process. Dr. Bergius received the Nobel Prize in 1931 for this contribution.
The process that Standard Oil developed - after Frank Howard of Standard Oil (NJ) Company visited the BASF facility in Ludwigshafen, Germany - involved the use of catalysts. These catalysts were so good that they could be used on oil to generate gasoline, kerosene, or diesel fuel. This was the beginning of "cracking," the basis for all future oil refining and the foundation for synthetic rubber production.
Returning to coal, a U.S. company is helping China to build the world's first commercial plant to turn coal into diesel fuel and gasoline:

China has a proven reserve of coal of one trillion tons and its annual output is one billion tons. The U.S. has coal reserves almost twice those of China:

Another process, simpler and less expensive than the full Bergius coal conversion, can produce a feedstock for the thermal depolymerization process.
So, it isn’t just turkey parts and swine manure that we could be filling our tanks with and lubing our engines with. We have a 200 year supply of coal.
