Just a quick pole. We discussed this way back when it started to get cold. My 4.4 V8 was pulling a pathetic 13-14 mpg's in the summer and now down to a solid 10.5-11.5 mpg's all winter (im at 22,000 miles). i live on the east coast in PA and do a mixed highway/town driving. more so in town. I tried going a little lower in octane with no difference in mileage, just some possible detonation (or so my paranoid mind thought). What is everyone else at? im gonna bring it up when i go in for service in a week or so..
