Preheat oven to 400 degrees F.
Arrange peaches in the bottom of a shallow baking dish; set aside.
In a small bowl, combine flour, oats, oil, brown sugar, and cinnamon. Stir with a fork until mixture is crumbly, adding more oil if necessary. Fold in nuts. Sprinkle topping over peaches and bake 15 minutes, until golden brown.
