Coat a 9 inch loaf pan with cooking spray and set aside.
Mix the flour, oats, granulated sugar, brown sugar, baking soda and salt in a large bowl whisking to combine thoroughly.
In a small bowl, whisk together the oil, eggs and vanilla. Add the egg mixture to the flour mixture and stir until all ingredients are thoroughly combined being careful not to over mix. Fold in the blueberries.
Pour the batter into the prepared loaf pan and bake in a 350 degree oven for approximately 50-60 minutes or until a toothpick inserted into the center comes out clean.
Cool the bread on a wire rack for 10 minutes and then remove from the pan. Allow to cool to room temperature.
The bread can be stored in an airtight container for 3-4 days and frozen for about 2 months.
