1. In a medium-sized bowl, mix the flour, sugar, baking powder, and salt. In a small bowl, combine the milk, egg, and oil. Stir the milk mixture into the flour mixture just until well mixed. The batter will be slightly lumpy.
2. Lightly oil a griddle or a large skillet; heat over medium-high heat until a drop of water will dance across the surface.
3. Spoon about 1/3 cup batter onto the griddle for each pancake. Cook until several bubbles burst on the top and the bottom is light brown. Turn and cook the other side about 2 minutes or until it is lightly browned.
