In a large bowl, dissolve yeast and sugar into water. Let stand 5-10 minutes.
Mix in the oil and salt.
Add the flour, one cup at a time, mixing and kneading until the dough is smooth and elastic.
Put dough into a greased bowl, cover, and let rest until doubled (about one hour).
Punch dough down, divide and form into 3 individual loaves. Place the loaves into 3 greased 8-inch bread pans.
Cover the bread pans and let rest until the top of the dough is an inch or two above the pan rim. About 45 minutes to 1 hour.
Bake at 375°F for 25 minutes or until golden brown.
Immediately remove the loaves from the bread pans and place onto a cooling rack.
