If I had to guess, I would associate the increase to the cooler temps in Atlanta. I'm no longer running the A/C most of the time which I assume that accounts for some of it. Perhaps the cooler air and fuel would also result in some gains.
We'll see if that holds up with the next tank since the temps have been consistent through it so far.

Does Atlanta have the crazy concept of a Winter Gas blend like CA does? Perhaps you folks switched over like we will in a couple of weeks.
Unfortunately, I have some unfavorable but somewhat expected news. I've since switched to a 245/35/18 tire in the rear Hankook Ventus V12s. I'm sure i'm running more front toe in other words more drag with not optimized alignment everywhere else. I'm now averaging about 27-29mpg. I've also been heavier on the gas since the car is *more* fun but i'm shocked my mpg has dropped so much. I was at around 30-34 during the break-in period and about 500 miles after, before switching wheels/tires and lowering it 20mm.
The alignment appt is on Thurs. I'm debating what to do with my toe. I normally run some toe in in the rear and some toe out in the front for performance purposes but I might forgo that keep toe at 0. If anyone notices this impact please share your findings.
