drive someone elses car and run out their gas.
any stops i make have to be on the way(same street) to my job. no unnecessary driving.when i car pool, everyone has to chip in on the gas and i get my money before they get in the car. i park at the train station and ride the train into the city(atlanta) to shop or visit friends, instead of driving directly to the mall or their houses. most of my friends live on the north side, while i live on the southside. i make them pick me up at the train station closest to their houses. i also make my best friend who doesn't drive take the train to my side of town, instead of driving the hour to her house.

^ that part of the post was wrong, sry
selecing neutral when stopped shuold be fine, some cars actually switch off their engnes automatically once stopped (unsure of duration). However, coasting when braking for red light does yield a worse mpg for some new cars as it requires fuel to keep the engine idling -new trickery and a bit of black magic stop this.

it was mentioned in TG when they dedicated half ofthe programme about fuel economy, unbelievable!

Here's how I got 52mpg out of my xB (which is rated at around 34mpg)

-Drive 5-10 miles an hour under the speed limit.
-Draft big rigs on the freeway in neutral. (this helps a LOT)
-Pulse and glide (get up to speed slowly, go neutral and roll as long as possible)
-Brake early and lightly
-Shift into neutral and roll to a stop at lights.
-Roll down every hill in neutral
-Inflate tires to 35-37 psi
-Get rid of weight (i cleared out the rear of the xB and saved about 60lbs.)
-Keep RPM's below 2k
-Keep your gas tank 1/4 full. No more.
-Get all your driving done very early in the morning before the sun is up.

5) manual transmission (no joke); or if automatic, shift to neutral during stops
6) prevent roads that require lots of stopping, use backroads to avoid heavier traffic


In addition to the above that I have already stated, it is better to fill up your tank when it is cold. The theory is that the gasoline contracts, therefore, making it more dense and giving you "more" gasoline than if you were to fill up during hot conditions.....

So, here's my revised list:
1) inflate tires to CORRECT TIRE PRESSURE; CAR MAINTENANCE
2) fill up tank in cold conditions (fill up when it is as cold as possible on that day of fill-up)
3) keep your weight minimal
4) don't "jackrabbit", keep your foot steady, don't have a "leadfoot"
5) reduce amount of cargo stored on the outside, prevent storing cargo on roof
6) manual transmission (no joke); or if automatic, shift to neutral during stops
7) prevent roads that require lots of stopping, use backroads to avoid heavier traffic

Hmm theres a couple of things as people already mention.
1.Like tire pressure+maintenance is always a + for the average non-mechanical incline people.
2.Try to prevent going places that has a lot of stop signs.
3.Less weight...so dont bring that second person with you unless you want to.
4.When riding in the freeway windows must be closed all the way...if its hot bare with it or use a/c instead of rolling it down.
5.draft behind a car.
6.When you see a light about to turn red cruise into it and brake slightly before getting there.
7.And of course if your very mechanically incline buy a lot of fuel management system. and you might be the 2nd person that has a freaking 110 mpg car.

1. Dont buy a turbo car
2. Dump your fat girlfriend
3. Attach giant magnets to the front of your car so you can stick to big trucks.

Seriously though, I think this subject is pretty well covered.

IT'S ALL ABOUT THE NEUTRAL BABY!! it saves big time on gas.. Automatic or Manual specially on coasting..

On Manual Transmission:

1. shift quick around 2000-2500 rpm (2000 rpm preferably for lower gas consumption)
2. when costing even though slow put in 5th gear or neutral ( just down shift when needed to accelerate a little, then put back quickly to 5th )
3. Always watch the rpms maintain a 2000 rpm or below on side streets.. Then 2500 - 2800 rpms on freeway.. (just feel out the engine every car is different)
4. Who cares if your slow off the line!? You'll get up to speed anyways.. It really helps when you don't jackrabbit of the line.
5. ALWAYS KEEP YOUR MOMENTUM if you could avoid braking to a stop or even braking just too slow down do it..
6. Timing on the stoplights, slow down and avoid going into an actual stop when your close to a stop light.. a car uses more gas to move when it is on a complete stop.

7. MY FAVORITE PART TURNING OFF THE ENGINE ON DOWNHILLS (it is very dangerous because the steering wheel is stiffed and the brakes are not that responsive.. take note after certain period of time your brakes won't grip no more so you have to start the engine back up quickly)

It saves a lot of gas but you need good skill to execute it. You can't just put it into gear when it is on neutral then the car is going fast you GOT to rev the engine up a little bit to a specific rpm for that speed so you won't feel the drivetrain pullback.. revving it on a specific rpm before shifting prevents stress or wear down the engine

On Automatic Transmission:

It is the same as manual transmission just be gentle with gas pedal and it would shift 2000-2500 rpm on it's own or even 2000 rpm below depending on the car you have.

I AGREE with this guy this what i do also.. maintain your momentum always have it rolling if possible

1. That is a hazard to you and the other drivers
2. Leave it in D. Unless using a manual. You will use more fuel from the auto up shift. Cruise control is prefered.
3. This will use more fuel. Just maintain a constant speed
4-5. Should be done at the same time.
6. You actually want to increase your speed on the downhill if you are going back uphill so you can be at the speed limit at its peak. If no uphill just get your foot off the gas pedal.
7. Wrong inflate to maximum tire rating printed on the wall of the tire. Not to some general number.
8.Correct
9. Wrong. Running under 2k rpms will damage your engine from extra stress.
10. Having to go to the gas station 4 times as often will cost more money than filling up all at once. Get rid of more weight inside the car.
11. Correct

1.You want to be over 2k rpms for prolonged engine life
2. As long as it is near 3k rpms 5th gear should be fine.
3. Wrong
4. Correct
5. Correct
6. Correct
7. Power steering and the brake cylinder is off when the engine is off. Never turn off your car unless you are at a complete stop.
8. Its called rev matching.
