In terms of maintenance, definitely check your battery. If you have even a less then perfect battery, your alternator will be working harder, negatively effecting your FE. Make sure your oil and transmission fluid are not only "fresh", but not too full, it will make the bottom end of your engine and transmission work harder.
Do you have LEDs?
In terms of aero, I would do a rear diffuser. It is relatively simple, easy to take off, depending on how you design it and can be fairly well hidden if you want it to be.
What part of Oakland? I assume you are staying well clear of the "Maze".

26 was an arbitrary number.
I really do not understand your logic concerning the battery. The battery simply holds energy, and has nothing to do with how much power is being consumed or the load on the alternator.
The transmission fluid in my tranny is in a closed system and is ridiculously hard to open and change the fluid levels. I keep the engine oil midway between the points on the dipstick.
I do not have LED's. I know they'd save energy, but the initial price would never be made back given the age of the car.
Looking into the rear diffuser, I'm afraid I don't have the expertise to make that.
And yes, I stay clear of the Maze. I don't actually live in Oakland, (Lafayette) but I work in Oakland.

How does this work? The more pressure in the tires, the less tire on the road, right? What would counteract this at higher pressures?
