Conoco and Marland both began producing passenger car motor oils as early as 1921. Marland held the patent for the first canned passenger oil product from the new Continental Oil Company founded in 1929. This product was called "GERM PROCESSED" motor oil. Germ processing was the first motor oil additive ever used by any oil manufactacturer. Germ Processing was a special oiliness additive invented and patented by two British scientists in 1918. It was made from castor oil components. In 1934, Conoco developed a synthetic version call GD-160, later called MDS. This MDS was the material referred to as "OIL PLATING" on cans and in advertising. GERM PROCESSING was chosen as the name of the first motor oil because it was a "germ of and idea"!? Germ Processed oil didn't come in refinery - sealed cans until the early 30's and was dropped in 1940 for Motorine oil a low cost Paraffin based oil. There were nine different Germ oil cans in those years.
