Agree. I never use oil in the dough, and it isn't essential at all. I simply treat olive oil as a liquid food topping and drizzle a little bit on the pizza before I slidit into the oven.
Italians don't use oil in dough, that is what's authentic Italian!
While I agree,there is not much need for oil in pizza dough,you folks are not helping the OP questions by simply saying you don't use it,or its not Italian to do so.Pizza making is not dogmatic,where only one way of making dough is correct.
I make doughs with or without oil.Depends on the pie I want to make.That said,a Pizza Shop in NY,that I grew up with,used oil,sugar, in their doughs,and it was owned/run by Italians.
That same NY Pizza shop,also sold Spicy Jamaican Beef patties,to please their customer base,yet no one working there was Jamaican.
