Your mileage may vary, but generally, most of the aero mods suggested on this website gained my del sol about 1-3 mpg per mod.
in my experience:
Stock car - 60mph steady state driving = 30-32mpg
All aero mods (front grill bock, smooth front covers, windshield wiper cover, side mirror delete, rear wheel skirts, underbelly pan) - 60mph steady state driving = 40-42mpg
All aero mods + driving habits - 45mpg
