mpg on this tank is up 2 compared to what I've been getting over the summer. Not sure if it's the cooler temps here in NC, or they switched gas formulation.

Very likely the cooler temperatures. Iirc 'winter gas' when it comes, has less detergents which could possibly hamper fuel economy. Either way enjoy it right now. I know when the weather gets on the cooler side here, my IS also perks up a bit.

up 2mpg. What sort of mileage are you getting?

indicated it's 38 right now. But it always reads about 1.5 mpg high compared to manual calc. So on average I'm getting about EPA rating. This is driving fairly normal, 10-15 mph over the speed limit, mix of highway and back roads, some city traffic. No hypermiling, but do run on "eco" mode.
