Dallas just switched back over to summer gas. I think. Got a 3 mpg gain on my last tank. Drove the same. Maybe they use Daylight savings as the cutover.

Might've had a difference in your fill levels at the beginning and end of that tank, or a different driving profile. It's a little early for the change, I think. (It's still Winter.)
