RE: IMPROVE GAS MILEAGE ..
Here's a Nice quote from that article that seems to fit well:
"Buying items such as fuel line magnets and other gas saving party toys is equivalent to opening a bag of manure with your face. It’s not only completely useless, it’s also stupid and makes you look like a fool. They have been proven not to work, and beyond that, hurt your fuel economy. So don’t buy that heap of rubbish, and if you’ve already got one, then discard it for the sake of the additional weight."
AKA: No the turbonator won't help you and No that 15 lbs giant park bench of a wing isn't going to do anything for you besides change the way people look at you...

RE: IMPROVE GAS MILEAGE ..
Some of that advice is just flat out wrong if you have a J30a (Accord V6 engine 1998-2002) or about newer gars in general
1. Using premium fuel will NOT result in better economy and will result in less efficient engine operation for the J30a (this has been proven on the dyno and at the track)
2. A/C does not suck up 20% fuel ecomony. Every car I have had since I can remember it was less than 2MPG difference between A/C and no A/C with the widows UP. All of my cars since my 1989 sable actually got better gas milage with the windows up and A/C on than with windows down and A/C off.
My 1992 Sable with a 3.8L got 32MPG with the air on at 75Mph and windows down
My 1994 accord with 140K+ on it gets 34.5MPG at 80 with the A/C on and 32.7 with the windows down and A/C off.
my 1998 accord with a V6 gets 33.7 at 78MPH with the A/C on and windows up and 30.8 with the windows down and A/C off.
3. The best thing you can do to get excellent fuel economy is to keep your foot AWAY from high rpm accelleration. Moderate (low mid RPM shift points) seems to work very well for my V6 car and slightly higher RPM for my I4 car.
4. Constantly taking your auto in and out of gear at stops will DEFINATELY wear it out faster. is the few pennies you have saved in gas worth the 3-5K for a new trans?
5. Defroster on a 10 minuite timer has a neglegible affect on fuel economy.
6. Cruise control will yeild better fuel economy than 99% of the drivers out there....becuase they are not usually paying attention to that up coming hill.
7. manual transmission numbers are bogus for the accord (and most likely all newer cars. For the 2006 accords the difference in weight between a manual and auto is a measly 66lbs and they are rated for the same on the highway (source autos.msn.com)

5-Speed Manual Overdrive 24 / 31 mpg (135HP non Vtec)
5-Speed Manual Overdrive 25 / 31 mpg (150HP Vtec)
I can sum up better fuel economy in one paragraph.
To get better fuel economy do the following: 1) use gas recommended by the manufacturer unless you have modified your car to use something different. 2) do not drive aggressively. Keep your car clean on the outside and inside and do not use it as a suitcase or toolbox. 3) Keep your car in top shape mechanically and do the recomended maint as outlined by the auto manufacturer. At highway speeds with newer cars use the A/C and keep the windows up. If you drive a early 80's or older brick, it really does not matter what you do since there is so much drag on the car anyways.

You really did your homework on that subject. Thanks for posting it for all of us to see...

RE: IMPROVE GAS MILEAGE ..
I have a 2005 Accord EX with 12,000 miles on it. Inline 4 engine, automatic.
24/34, huh? If I am very careful I can get about 32 mpg in straight 65 mph highway driving. My lifetime average for this car, highway and city, is 24 mpg. City driving is 25-35 mph, nothing faster around here. I drive a 200 mile round trip every other weekend. Otherwise, all driving is in the 25-35 mph zones of this town. I realize that the town driving is on the slow side, and that my daily drive (6 miles round trip) is on the short side. Nevertheless, this is the first time I've had a car that doesn't get at least the EPA estimate. Did Honda stretch these estimates a little more than most?
And, BTW, I tried using 92 octane for about six weeks. I actually got about 1.5 mpg better mileage with the higher octane gas, but it's about a wash cost-per-mile wise.

RE: IMPROVE GAS MILEAGE ..
what rpm should 1 drive at...as a rule of thumb i try to not to exceed 3000 RPM when changing gears ( 98, 4 cyl ex 5 spd)
BUT like riding a bike, in high gear and not enough speed, you have to pedal HARDER.. so im thinking at too low an RPM it hurtds the engine.. is this a correct assumption on my part. crusing on regular roads if im at 45 mph, in 5th gear the rpm is at like 1800.. exactly at 50mph it hits 2000.. tho it seems to me that its better for feul is that working the engine too hard? what do u guys think? btw, my english is fine, im just a bad typer :P...

RE: IMPROVE GAS MILEAGE ..
I'd have an easier time believing in a lot of the soi-disant gas-saving gadgets on the market if I weren't a science major. Best and briefest advice: get off the long pedal. Accelerate gradually to moderate top speeds. When driving, anticipate having to slow down or stop, and get OFF the long pedal well in advance. A significant fuel savings may be realized by just not being in so much of a hurry all the time. Get there 2 minutes later; so what.

I have this pill I put in whenever I put gas, which supposively increases my mpg 20%. I tried it and it works! It's pretty cool.
