well, here's to my first post ever since I've joined SL 
.... I'm a person who's picky with precision ;)
I keep an eye on my MPG every full tank I do. I have kept enough receipts in my car that I've totaled almost $400 just gasing up my car in almost 4 months; the first 4 months since I've owned my tC 5-speed.
I have seen my mpg average up to 34.5 with drafting semis ~69-72Mph (dangerous I know, but it was a test to see if my MPG would really improve at a higher speed than tested in a mythbusters episode).
In most cases these days, I usually see 28.2-29.5 MPG, 80% highway, 20% city; rarely do let the car idle for longer than 1.5 minutes. I usually time the same red lights on the roads most frequently travelled; so when I know I'm going to sit long, I think.... it's better to shut off for 2 minutes than sit for 2 minutes idling.
Now on to the stats from precise calculations and conditions.
2005 SW tC - (Bought @ 36005 miles) now with ~46900 miles. (6 months owned)
below stats were calculated with balding tires, estimating about 40% treadwear left, slight misalignment...
~72-73MPH cruising, 80% highway, 20% city, avg mpg = 28.5, style = below aggressive city driving.
~69-70MPH cruising, 80% highway, 20% city, avg mpg = 28.2, style = same.
75-76MPH cruising, 70% highway, 30% city, avg mpg = 27.5, style = same.
I say below-aggressive as I rev it close to redline about 6-7 times on avg per tank.
I just got new tires, I'm a firm believer in proper psi + great treadwear = increased MPG.
Also noting, that the empty light turns on at around 11.2GAL for me, it used to be 10.7ish when i first got it....don't know if it's adjusting to my driving style...can it do that for when to notify me to gas up?
the most i've gas'd up was 12.1 gals. the mpg fell between 27.5-28.
Most miles on one tank, 355 miles on the NEW tires, gas'd it up with 11.2 gallons afterwards... needle was touching the bottom mark.... weird, how I used to get 320-335 on a tank and gas'd up to 11.1-11.45 gallons with the BALDING tires.
stump'd on that. :X maybe some vapor issues? who knows...
well here are my stats to share with the rest of ya!
(Those who claim near 400miles/tank + .... that's quite a run, I'm not doubting u but if u take some sample #'s....
400mi/14gal = 28.57MPG, quite a feat, but risky run to your internals :X
425mi/14gal = 30.35MPG, again, scion claims 27highway mpg, 14gallons is running almost dry....too risky for me.
if ur not the risky ones
400mi/11.5gal = 34.78MPG, all i say to this is, civics=FAIL.
400mi/10.5gal = 38.09MPG, this is where hybrids = FAIL.
thanks any feedback is appreciated, negative or positive!

Test #6 Avoid Excessive Idling
If you turn off a light bulb as you leave the room you'll save electricity. If you turn off your car you will save gas. Obviously. But related questions are more difficult to answer. If you're only stopping for only a minute, is it better to shut off the engine or keep it idling? Should I shut off the engine in traffic? How much gas will this save? What rule of thumb do I use when trying to save gas this way?
Method: We took two cars and drove a 10-mile route stopping 10 times for two minutes. We shut down the car each time. Then we drove the same route at the same speed and let the car idle for two minutes.
Conclusions
The good news is that you can drastically improve your gas mileage. The caveat is that you have to change your driving habits. If you are willing to change, you'll find many related benefits too: no speeding tickets, greater safety, reduced stress and lower repair bills for tires and brake pads. In the long run this will save you money. And who knows? You might like the new you.

Avoid Excessive Idling
Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

Myth 3: Shutting off and restarting your vehicle uses more gas than if you leave it running. The bottom line is that just 10 seconds of idling uses more fuel than restarting the engine. As a rule of thumb, if you are going to stop for 10 seconds or more - except in traffic - turn off the engine. You’ll save money, and you won’t produce harmful Carbon Dioxide, the leading greenhouse gas.
Idling gets you nowhere - and it can be costly. Excessive idling wastes an enormous amount of fuel and money and generates needless greenhouse gas emissions.
Restarting a car many times has little impact on engine components such as the battery and the starter motor. The wear on parts that restarting the engine causes adds about $10 a year to the cost of driving - money that you’ll likely recover several times over in fuel savings.

Fact: Idling wastes fuel. In this time of ever increasing gas prices, needless idling burns your hard earned dollars through your exhaust pipe. And remember that fossil fuels are a non-renewable resource and are being depleted in the face of ever increasing world demand.
- Idling your vehicle for more than just 10 seconds uses more fuel than restarting your engine.
- Idling your vehicle for just 10 minutes can use as much fuel as it takes to travel 5 miles.
- Idling your vehicle for 10 minutes a day uses more than 27 gallons of fuel a year.

Idling gets 0 miles per gallon. You will save more gas by turning the engine off and restarting it again if you expect to idle for more than 30 seconds. The bottom line is that over thirty seconds of idling uses more fuel than restarting the engine.

Don't be an American idle. Idling for more than 10 seconds uses more gas and emits more global warming pollution than restarting your car! Also, the best way to warm up a car in winter months is to drive it. When the temperature is below freezing, give it 30 seconds—that's all you need.
