You guys are in the Northeast (like me). Keep in mind that the winter blend fuel has already arrived, and with higher emissions allowed and cheaper quality gas also comes worse mileage. My old 302-based clunker dropped a couple of mpg over the last two weeks despite driving with a feather foot.
I'm pretty sure this is due to the low quality winter blend gas.
In other words, come spring, your mileage may improve again.
YMMV
