Feel free to use this thread to make suggestions or post additional tips.

It's a work in progress, of course, as is most of our driving.

This is pretty good, thanks. A lot of good tips.

I started a similar thread on maxima.org, even before I saw this thread.
The Official increase your gas mileage thread. - Maxima Forums

I do disagree with a few of the tips here, especially #24:
24) Drive when it's warm out
If you have the flexibility, time your trips to coincide with warm temperatures (ie. middle of the day) rather than cold (night/early morning).

Cold tires and drivetrain experience more rolling and mechanical resistance, and a cold engine is less efficient.

I believe that, so long as the engine is at operating temperature (and cold ambient temperature has little affect on an engine reaching operating temp.), a car is more efficient in colder weather. Heat is truly the enemy for efficiency. The colder the ambient temperature, the more efficient your car is. Cooler, more dense air into the throttle body, reduced coolant temperatures, reduced oil temps, etc. Not to mention if you drive at night, you'll be less likely to use AC, there will be a tendency for fewer cars on the road, you'll make more green lights, etc.

Anyway, thanks for the great tips!
