Not necessarily. I can't see the images (at work right now and the firewall blocks most sites/pictures) but depending on the type of supercharger they'll employ fuel mileage may remain unchanged. If it's a roots type blower then yes you'll take a significant hit to fuel mileage, but if it's a centrifugal blower (commonly reffered to as a procharger and due to higher operating temperatures usually requires an intercooler) fuel mileage often remains unchanged in light/mid-weight vehicles. In heavier vehicles centrifugal superchargers, like their turbo rivals, often increase fuel mileage.
