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.
A long stretched theory... but maybe you're slowly changing your style of driving without noticing, as it still feels like a habit? Over time, I have improved my driving style by giving the car a little more excitement, but I've also found myself using plenty of engine braking and such, that I still maintain an average of about 31.5 mpg.

I mean there is certainly no miracle to this, as the car wouldn't decrease its gas usage for no reason. Seems like you are just continuing to become a "better" driver without noticing, as it's long term.
