Fuel milage with 2.7L

[N106FM]

I have a EX with the 2.7L and a automatic. For the first 4000 miles I was averaging 23 miles to the gallon and that was with the AC on. The last 2000 miles (mostly with the AC off ) has been averaging 18 miles to the gallon. I drive a mix of about 60% highway and 40% city. The car has a little over 6200 miles on it. I am using 10-30 Castrol syn oil. Anyone have any ideas what mileage I can expect?

Other then the gas mileage the car has been great.

N106:

Do you live in the Northern part of the country where the temperature has recently dropped?

If so, I'm wondering if the gas stations are already serving up their winter blend of fuel that gives less miles per gallon due to increased ethanol content. I've noticed that my Spectra's mileage takes a big nosedive after it gets cold out.

I'm running a 2.7L 2006.5 which at this point has just over 50k miles.

I'm getting about 26mpg. Seems like your mileage is awfully low.
