My MPG continues it's slow climb upwards which I still find odd. As a reminder:
90% of my miles are commuter miles along the same path.
90% of my fuel is bought from the same vendor and station (Racetrac)
The tires have primarily been the same.
I drive my car the same. First away from the light, a little too fast on the curves.
My average speed along my commute is @50MPH with stretches between 35 to 65.
The car is averaging about 3MPG more now than when new. I have no idea why.

Tcoat had a theory at one point that the increase was the engine breaking in, then it would eventually head the other direction as wear and tear took it's toll. At @180,000 miles I would think we'd be seeing the drop by now.
Thoughts? I mean besides "stop driving like your Grandma" because trust me, that would not help my gas mileage at all. She was the speed queen of the KY backroads.
