I have a 5 speed manuel,i think the milage should be higher,i'm getting an average 360 miles/tank,that sucks!,does the a.c. run off the engine like my old Contour?,even on the Contour,i got over 400miles/tank.Also,I was told to use 87 octane gas.
And that's if you run the tank dry.That's 27.2 mpg, not really out of line (it's rated 26 mpg city, 33 mpg highway). Keep in mind the tank is only 50 liters (13.2 gallons) in these cars.
