My 2008 package 6 Prius with about 2600 miles on it is getting poor gas milage. My first interstate run of 65 miles gave me 42 mpg. After that it went down hill. I spoke to the service manager. He told me I have to "Learn how to drive it." That's not in the owners manual. He told me to gun it and then coast with cruise control. Huh? I was so sad I found myself yelling out the window every time I saw a Prius; "What kind of gas milage are you getting?" The answer was always Mid to upper 40s. I found 2 other Prius owners who use the same Hess station and drive normal like me with the a/c blasting. They even drive the same roads I do. I was desperate enough to ask them to push their "Info" button to display the computers opinion of their MPG. One read 44 the other 46. Mine read 36 mpg. When I used my calculator to divide the miles driven by the gallons pumped it came out to 35 MPG. I attached a picture of my last computer read out. I am not complaining, just explaining. I would appreciate any wisdom from my Priuschat friends.
