I have a 2006 PT with 83k miles on it. It is also the base manual no a/c. When I bought it I was getting an average 27 mpg on 87 octane, I changed out the plugs with Bosch Platinum +4, standard Duralast wires, air filter, and due to them malfunctioning the cam position sensor and #2 o2 sensor. I now average 29 mpg with mostly city driving and I'm not always friendly to the pedal on the right (the car is really fun over 3000 rpm!). The air pressure in your tires will also greatly affect your mpg. I'm still looking to see if the 2006 pt's had a programming update for the rough idle because mine has been doing it for awhile although it has not affected drive-ability any.
