Lost Fuel Range?

Usually to a tank of gas my fuel range will be around 360 miles on my 09 Cobalt, sometimes as high as 400+. I found that one time when I was in New Hampshire on vaction for some reason my fuel range was sky high.
Well I nearly filled my tank yesterday and only went 10 miles since and my range was down to 273 miles. Does the weather and use of heat(I don't use it full blast or anything) Would this affect my fuel range.
I just rely on having a good fuel range cause work brings me travelling alot!

I think my daughters let the car run, while you probably don't.

My daughters don't pay for the gas so they don't care. Can't wait for them to leave the nest.

There is a different formulation for gas in the winter time that does cause your mileage to go down I believe
