Dissolve the yeast in 1/2 cup warm water with 2 teaspoons of sugar.
In a large mixer bowl combine sugar, salt , oil, 3 cups warm water, and yeast mixture.
Add half the flour. Begin to work the dough in a mixer with a bread hook. As the mixture comes together continue to add the flour. Add the flour until you have a soft dough you can handle. It may take a little more flour or a little less depending on the flour you use.
Turn the dough out on a floured surface and knead for about 5 minutes.
Place dough in an oiled bowl. Cover with a cloth and let rise for 45 minutes.
Punch down and rise again until it doubles in bulk. Knead lightly, shape into loaves, and place in well-oiled bread pans. Cover with a damp towel and rise again while you preheat the oven to 250
Bake at 350 after the loaves have doubled for 30-35 minutes.
