Low Mpg (19mpg on Computer)???!!!

The computer display is showing 19 mpg. I need some help trying to figure out what could be wrong. It is a 2007 lt with the 2.2 liter and has 43k miles on it. Now I know that the gas stations have switched to the winter blend but this is still very low gas mileage. What can I do? Im not due for a oil change yet and had tranny flush in may. I need some serious help.

Winter sucks on MPG. I drive a round trip of 11 miles for work and I went from 28.6 now to 20.2.

There are a couple of factors working against you. The winter blend and the winter temps. The cold brings denser air, which takes more power to overcome. This, combined with winter blend gas, cut hurt mpg bad.

To get a good idea if anything else is wrong we need to know the following:

1. What percentage of your driving is in the city vs. hwy?
2. Do you warm up your car before you drive it?
3. Do you sit in your car with it running for extended periods of time?
4. What kind of mpg did you get in the summer?

I dont warm it up or let it sit for extended periods of time. I got 24-25 average mpg in the summer. This is kinda suckish cause I had a 06 malibu maxx lt with the v6 engine that I actually traded in for this car that I have and it only got 1 mpg less IN THE WINTER!! Theres gotta be something going on. I thought about going ahead and replacing the spark plugs and air filter but didnt know if that was going to do much good. I thought about taking it into the dealership but they would tell me its normal mpg but I tell you I really do not think its normal cause there are suvs im sure that get the same mileage.

it really comes down to driving habits then. Because even supercharged I don't get that low mpg because I don't drive like an idiot by flooring it and all that crap. I mean in my little acura I've been getting over 400 miles on a tank just driving around town.

Um I dont floor it at all. I have an automatic and accelerate normally up to the shift points of between 3000-3500 rpms.
