This fillup I went around 400 miles on 11.356 gallons, which means I was getting almost 36mpg overall!

I feel like I've hit a ceiling here, ~40mpg highway when I'm careful (~44-45 is possible if I stick in the slow lane doing 50, piss everyone off, and not have to brake a single time), and 25 when assaulted with stop signs at every block if I roll around super slowly. I'm pretty happy with this, but it's a little short of what I was hoping would be possible.

The highway figure could be pushed a little higher with a slightly taller tire, but these tires have tens of thousands of miles left in them. If I got a wideband emulator for the O2 sensor and had the car run lean, I imagine I could bump my highway average up a little and my city up by like 1 mpg, but 200 dollars buys a whole lot of gasoline.

I may try leaning out the fuel map a little more for city driving but it's not really going to save me much fuel.
