I'm betting there are a few of us here that have done MPG-unfriendly mods. Maybe it's a heavy sound system, a lead foot, heavier wheels/tires, or neglecting maintenance.

What have you done? How bad did it hurt your mileage? Were you able to get your mileage back, or did you care?

I'm running sticky summer tires that are heavier and wider than stock. I went from an easy 43/44 MPG to a difficult 40. She looks really good.....for a commuter.
