If you want to quantify the potential mileage improvement, you can mount an airspeed indicator pitot tube just ahead of the nose of your car to determine what airspeed your car is experiencing while drafting (you'd need to try it in several locations to get the average airspeed experienced by the front of your car). Then, for example, if the drafting airspeed is half your ground speed (assuming no winds), the mileage you get while drafting at that airspeed is the mileage you would get if you halved your Cd from its current value.
