Residual moisture and sulfur and other residual reducing agent impurities contained in automotive fuels and fuel oils are removed by adding to the fuel a chromate compound or a solid acid and circulating the fuel through a filter system comprising at least one filter made up of a cellulosic material attached to a D.C. power supply, and containing a chromate compound or a solid acid, whichever is not previously added to the fuel.
