Just filled up, FE for the latest tank was nominal 41.6 (MFD), and filling up to the second automatic shutoff of the pump, calculated out to around 39 mpg. And it's not even that cold yet.

Though my tire pressure warning light did kick on the other day, and I finally got out to buy a tire pressure gauge (yes, didn't own one before! Didn't care that much on my old car, lol, but now, oddly I do.. ), and added some air to all 4.... Shot for around 42/40, really need to check again to see where I ended up, as I had to drive a bit to get there so not completely cold when I inflated. I'm hoping that will buy me back some of the FE I've been losing, too.

But cold's coming.. pretty chilly today, and I've already had a good 3 or so commutes where when I got to work it was below 40 mpg on the MFD graph. And I stuck with only taking it 600 miles for the first time since I got my first 700 mile tank. Figuring won't be long before I have to fill up after 500 miles to be safe. :\

And that's without snow or sub-freezing temperatures still! Just goes downhill from here for the next 3-4 months. Very sad.
