Just got an `10 XFE Cobalt (5spd)

msrp was 16k, out the door 10.8k
30miles on the odometer when i bought it


first tank of gas...
cpu said i avged 38mpg
receipt calculated to 35

2nd receipt 35
cpu avg 36

3rd receipt 34
cpu avg 35

4th receipt 31mpg
cpu avg 32

WHAT THE @#$#@$
I'm losing mpg doing the exact same drive everyday

I drive 65-70, its a long flat road to work, with mild city mixxed in, but all redlights

I coast to the reds in neutral

my xfe had a gas cap problem, but they replaced it
do u think i should just reset my cpu by d/c the battery for 1hr or so

I'm getting lower and lower and its driving me nuts.
