Preheat your oven to 350°F (175°C) and grease your loaf pans with butter or cooking spray.

In a medium mixing bowl, combine the diced peaches, vegetable oil, sugar, eggs, sour cream, and vanilla extract. Mix until fully blended.

Sift in the all-purpose flour, baking soda, and salt. Gently fold these dry ingredients into the wet mixture until just combined.

Pour the batter into the prepared pans, filling about two-thirds full.

Bake for 25-30 minutes if using mini loaf pans, or 50-55 minutes for a large loaf. Check for doneness with a toothpick.

Allow the bread to cool in the pans for 10-15 minutes before transferring to a wire rack to cool completely.
