How to improve the gas mileage!!!
I live in South Florida, use the a/c, (really have to here) drive it in manual most of the time, put midgrade gas in car, put in N when idling for long periods of time, what else can I do to improve gas mileage, Some of you guys are getting 40's and higher. I am lucky to get 35 city. What gives?

What causes you to lose so much air pressure every month? That is not normal and will effect your MPG right there. Is it all tires or just certain ones?

Are you lugging around any extraneous "stuff"? This will kill mileage in a small engine/small car.
As GLSONN stated, getting really good mileage is "boring", slow lane, coasting, etc.
How many miles do you have on your Smartie? Have read some posts that said mileage improved after 1-2k miles.
Can't say much specific to a Smartie as I am one of those waiting for the pleasure of owning one.

My tires lose 3-4 lbs/sq inch pressure every month
Id have that checked and fill them up with nitrogen instead. Nitrogen is molecularly bigger and will seep out less. most tire stores now have it as an upgrade option, Costco uses it on all their tire replacements.

driving in automatic is best and don't stomp on gas for acceleration. the car is designed to upshift fast to get better mileage. it needs to break in for 1st 1000 miles then will tighten up on the compression, etc. you need to learn a new driving style which is more leisurely= better mileage. I get 39.5-40 in town and 41 on hwy. I use regular gas

What I do:
To reduce A/C use {harder now that it's almost 100} use a solar/reflective sun shade & crack windows 1/2 inch or so when parked. Try to park in shade when possible. Use a shade over the shade in the roof to reflect the sun. And driving with the window down uses less gas than the A/C.
Accelerate slowly. Imagine a raw egg under the gas pedal. I also find I get better mpg in auto rather than manual. Try to stay below 3000 rpm.
Remove any excess weight from vehicle. If it doesn't need to be in there leave it at home. Keeping it clean inside and out seems to help.
As mentioned already make sure your tires stay properly inflated.
Track each fillup. Record where you refueled, driving conditions, and factors such as rush hours. You may notice a pattern of when you get better mpg vs. not as well.
Also I didn't see much improvement until after about 1000 miles. As I get more miles the mpg seems to get better.
Use top tier fuel. http://www.toptiergas.com/retailers.html
Don't let the car idle. It's not like cars years ago when it was cheaper to let them run at a train crossing than turning it off and starting again.

Your pressure loss seems excessive, and indicates a problem which needs to be tended to: I suggest you check out this product ...
--------------------------
http://www.gemplers.com/product/G64511/Ultraseal-Tire-Sealant-Comme...
The claims for this product include:
# Permanently seals tire punctures caused by objects up to 1/4" in diameter
# Tire sealant protects against rust and corrosion
# Eliminates porosity leaks
# Use in highway-speed or off-road equipment (high speed tires must be balanced before installing Ultraseal)
--------------------------
Item #3 could address your pressure loss. I don't have my smart yet, but I WILL install this product. Especially since smarts have no spare tire. I have no financial interest in the product ... but, it sounds good to me.

Interesting discussion. Smart Center has encourage me to use the manual shift and ignore the computer upshift indicator. They suggested looking at the tac and listen to the engine. Indicated in auto it is shifting early causing the on-board computer to rich the fuel in response to lack of RPM? End analysis in auto my max was 40+. Recent tank of in town and 135 mile road trip produced 46.11 - not bad and still less than 2000 miles on engine.

Anyone try using synthetic oil like Mobil1? I am on the waiting list so I don't know what kind of oil comes from the factory, but I have had good results for over 10 years with Mobil 1. It seems to really reduce engine friction and definitely slows wear down.

Gas is Gas, Right?
Brand of fuel makes as big a difference in overall mileage as grade, but it shouldn’t.
We have had reports of fuel mileage being affected by where you buy your gas. I was able to run some tests on a car with a customer complaint of low mileage. We ran the test by filling at a station we often use and we got 43mpg. We came to the conclusion that if the customer was honest (which you all are) and was using the 91+ octane grade, then the only answer was where he was getting the gas.
There is a huge problem with this theory, however. I found some information online with regards to fuel quality standards and found out that statistically, it is unlikely that the gas station is the real reason.
So why are so many people reporting that tanks filled at discount and independent gas stations get worse mileage all over the nation? The real answer is… they probably are, but don’t report the culprit station. Dig deeper into the report and you will find that very few stations are actually tested. The other problem is that very few people actually complain to the Department of Agriculture about bad fuel.
If you feel you have been charged for premium but got something less, call your local agricultural department for information on filing a complaint.
For the complete test results use the link below.

what are the gas saving for the ones who are trying the "hyper mile" driving ? I am using it with my current car and do see the difference already...the current is a PT Cruiser
