In a large bowl, dissolve the sugar in warm water and then stir in the yeast. Let rise until the yeast forms a creamy foam.
Mix the salt and oil into the yeast. Mix in the flour cup by cup. Knead the dough on a lightly floured surface until it is smooth. Transfer to a well-oiled bowl and twist the batter to coat it. Cover with a damp cloth. Let rise until the volume doubles, about 1 hour.
Beat the dough. Knead for a few minutes and divide in half. Shape into loaves and place in two well-oiled 9x5-inch loaf molds. Let the dough rise for 30 minutes or until it has grown an inch past the molds.
Bake at 175 degrees Celsius (350 degrees F) for 30 minutes.
