Oil and oil additives separated from a contaminated solid particulate filter medium, preferably diatomaceous earth particles. Portions of a mixture of oil, oil additives and the filter medium are compressed into pellets that are extracted with liquid or supercritical CO. sub. 2 to form a liquid solution. The solution is separated from the pellets and then heated to 20. degree. -60. degree. C. at a superatmospheric pressure to drive off CO. sub. 2 gas, which is preferably recycled by compression into liquid or supercritical CO. sub. 2.
