I feel fine already, I just like people to be accurate when they make a claim.
You might want to look at the window sticker for your car, my car states 25/33 combined 28, though if I calculate the average myself it would be 29. I am at 27.99 over the 9,000 miles I have had the car, including two winters, one with snow tires, and engine break in.
.01 off the mark. I am not heartbroken.
I have no doubt you think the EPA numbers are way off, and some drivers totally agree with you, while others do not. The average driver is close to the Combined Average number on their window sticker, using Fuelly as the resource to mine that data.
Driver style and the type of driving make a difference, you haven't stated what your typical drive is like, so I can't comment on why you might be seeing lower than average MPG from your impreza.
