In a large pot, combine potatoes, garlic and 1 teaspoon salt. Add enough water to cover the potatoes. Cover and bring to a boil. Lower heat to a simmer and cook for 10 to 15 minutes or until potatoes are fork tender. Drain and then transfer potatoes and garlic to a bowl.
Add cheese, oil and milk to potatoes and then combine and mash the potatoes with a potato masher. Season with salt and pepper to taste.
