I just gained back 1.0mpg by replacing my front two brake OEM calipers, which were dragging, with two new ones. The inner pads were wearing 4 times as fast as the outer pads were. I caught in time before they started wearing into the rotors. Installed them about two weeks ago and noticed the mileage increase doing the same route each day. And another bonus, no more black dust on the front rims.

Well, I've got an answer! I took it to the dealer. And they found my MAFS to be dirty. I will be getting it back tomorrow after they do some more test driving. But so far they have taken it from 14.7-15 mpg to 18 around town. I will find out tomorrow if they jumped on the freeway at all to get that, but as of right now they said around town. YIPPIE!

Mass air flow Sensor. First item after the air enters the air filter.
