Preheat oven to 350 and grease and flour two loaf pans. Combine sugar, cinnamon, flour, nutmeg, soda, and salt and mix well. In a separate bowl, combine oil, eggs, pumpkin, and water. Blend wet and dry ingredients together, until just moistened. Pour into prepared loaf pans. Sprinkle tops of loaves with oatmeal, if desired. Bake for 45 to 60 minutes, or until toothpick comes out clean.
