Mix the oil, sugar, and eggs, beat well. Stir in the flour, then add the cinnamon, baking soda, and baking powder. Add the grated zucchini and chocolate chips. Bake @ 350 degrees for 45-55 minutes or until a toothpick comes out clean. I used a bundt cake pan for this recipe. Invert onto plate or cake pan after cooling for about ten minutes in the pan.
