1st tank 53.36mpg mostly city AC on

Bought an 08 touring 6. Stealer filled the tank and the car had 6 miles on it total. I drove over 500 miles and only had to put 9.5 gallons in it. It was 10% freeway and 90% city all with the AC on.

My 4x4 GMC 2500 Diesel 9,000LB truck is sitting parked with a for sale sign on it (did NOT get any calls either).

Man I could not be happier about the MPG on the Prius. If it goes up after break in Its just icing on the cake.
