Thread: gas mileage

racecar

I was curious about the MPG on the 02' GT I just bought. Maybe it needs a tune-up. I have had it 1 week now and when I brought it home the display was showing 12mpg. The next day it was up to 13. Last night when I got home it was up to 14.5. I have only driven it to work and back which is 14 miles round trip and on a parkway at 50mph. So I guess my question is: Does the onscreen display immediately change when you drive, or does it take some time to calibrate itself to how a person is driving? I'm an "easy" driver, not hard on the gas or driving over the limit. The kid I bought it from I'm sure had a heavy foot and wasn't worried about getting good mileage. Even though the car seems to run nicely, I'm going to tune it up and run a can of Seafoam through the tank just so I can start my own maintenance log. I just expected the mileage to be closer to what the factory specs says, so I was surprised to only see 13's and 14's on the screen.
