Sock-it-to-me Cake!

This cake has played a very important role in my life. I'm sure it is a recipe passed from generation to generation and it may one day play a role in world peace, introducing Sock-it-to-me Cake.
Is it as moist and delicious as the photo makes it out to be? Yes, and some! Here's how you make it:

1/3 cup Crisco oil or Puritan oil
1/4 cup sugar
1/4 cup water
4 eggs
Filling:
2 Tablespoons reserved cake mix
2 teaspoons cinnamon
1 cup finely chopped pecans

Preheat oven to 375, combine filling ingredients and set aside. In a large bowl blend cake mix, sour cream, oil, 1/4 cup sugar, water and eggs. Beat at high speed for 2 minutes.
