putting your car in neutral uses gas, when your off the gas and coasting the engine uses the rotations of the transmission to stay running, when you put it in neutral, its not getting the rotations from the transmission and it keeps your injectors running to keep the engine running.

Thank you, i did an experiment with a wideband, and would watch it lean completly out, and when in netrual, it would keep air/fuel ratios around 14:1...its also on howstuffworks.com

shutting off your car while moving to save gas is absolutely asinine... both from a safety standpoint and since your fuel injectors magically go to 0ms pulse width above 1500rpm when you let off the gas while still in gear.
look it up boys, that's how it works.

Using the unharnessed potential energy created by the alternator isn't a scam, case and point; regenerative breaking.
And because I can already forsee someone mentioning that hybrid vehicle's with electric motors' dont use alternators', **** you; electric motors in the transmission.
I hope your brain is still full of ****..

Wow 31 MPG, 500+ miles to one tank!
I use my trip odometer thingy to measure how far I go with each fill up and not once has it ever gone above 300.
My MPG has been stubbornly at 21-23, ever since I got my car. Someone must have swapped your engine with a 4 cylinder. lol

Well, see, if you have these things called muscles, you can use them to manually brake and manually steer your car. Its possible, I'm only slightly muscular, and I did it. People always did it up until the 1960's when power brakes and power steering started to come standard in cars. And as far as it being illegal, so begs the question... who really gives a flying ****? Technically going 46 mph in a 45mph zone is illegal, not stopping at the white line at a stop sign is illegal, jay walking is illegal, but people do these things all the time.
#53
thats why he said keep the key on engine off, steering wheel wont lock then...and ive shut my car off while coasting a few times, your brake booster holds enough vaccum to allow your car to stop at least once incase of an emergency where the engine stalled or blew up...so youll still have brakes as long as you dont ride them..and i havent had power streering in 2 years...i can still turn just as fast when moving...so theres no difference to me when i shut my car off...but like he had said before dont do it in traffic
#54
Older cars that did not come with power steering have their steering racks designed differently. When you disconnect your power steering, or in this case, turn your car off, you're working against the resistance of the fluid in the system to steer it.

extreme econo driving lol
i get 560km / tank (61L i believe) driving normally -not super econo- but no wide open throttle either and 30% highway driving = 10.9L/100km. 00vi, de-k injectors, y pipe back. not bad for having 1 bolt holding down egr tube (inlet side,egr code, oops) and no iacv plugged in lol so at idle i waste fuel for having an inefficient idle setup (for now). once all is done and tune i might be able to see 600km.
i remember getting around 490km/tank with 1 bad o2 sensor on USIM. OP, get a y pipe, K&N replacement filter and you might get an extra 2-3mpg... swap in a 5spd with flywheel and you might see 35+ mpg!

AFR goes off scale 19.9 when in gear with no throttle, down a hill
AFR goes to 14.7 when in neutral coasting down a hill
Because IPW is near zero in the former situation, and in the latter, ECU will add fuel for 14.7.
Case in point, leave it in gear to get better MPG.
#58
With this tank-full I never passed 2,000 rpms and mostly stayed at 1,500.
I cruised at stops and lights. Drove like a grandmother.
I got 28 mpg in city.
I usually get 26 in city.
My car is well tuned, no lights, synt. oil, AC off, windows up with 165,000 miles.
I think this is the best I can do.

If you own a max and you cant achieve more than 300 to a tank of gas give me the keys and youre credit card and ill show you how to do it... its called maintenance and repairs..18.5 gallon tank and an average of 25 mpg... do the math..even at 21 mpg thats over 300... therefore.youd be getting about 14 mpg or less with an 18.5 gallon tank...when i drove to PA last summer i filled to FULL.. meaning car couldnt take anymore at all drove.to PA and slightly round town while i was there and probably back to jersey before i NEEDED gas...

when in neutral the car will roll along farther than when in gear. Rotational mass.
In gear you have the rotational mass and frictional losses of the wheels, transmission, and motor to consider.
Out of gear you have just the wheels.
So on the positive side, leaving it in gear saves gas.
On the negative side, leaving it in gear slows the car down faster.
I wonder if it's a wash. Perhaps not.
And to go further, the bigger and heavier the rims you have on your car, the better it will get rolling along in neutral because the momentum derived from the rotational mass of the heavier wheels would make it roll along farther.

Just my experience here.
I got my 95 SE last August. The only time I've gotten below 30MPG highway was between late Jan. and end of Apr. Nothing different on my part, same boring drive M-F, cruise on at 70/71MPH. I got 24.3 - 25.8 MPG. It was like someone flipped a switch and BAM, crappy mileage.
I say it was because of "Winter" fuel. They change the formula during what's expected to be the coldest months.
Three weeks ago, BAM, 30+ MPG.
Also, watch out for what your pump dispenses. I have a five gallon gas can with markings at 1 gal intervals. The pump said 6.2 gal but the can said 5. I've used this can for years and it's always matched. I walked inside with the tank and showed them. They didn't even hesitate to offer me a full refund in cash. Good thing I took a cell pic of the receipt and pump meter because they kept the receipt and by the time I got to the pump, it had been zeroed out. This was at a busy BP station. When I got home I printed the images, wrote a letter to the County auditor and dropped it off the next day. The lady who gave me a receipt for all of that said "oh great, another example." When I drove by the station the next day, that whole row of pumps was taped off.
I've heard this is happening much more frequently, so check your meter with your mileage. If it doesn't look right, it might not be.

I used to have Staggered G35 17s but they felt heavy....lost some style points and got myself some NA 300zx wheels. Felt the difference right away. The best I've gotten in 26mpg. 391 miles on a 15gal tank. I do a lot of stop and go on every block, a lot of idle. Damn Los Angeles is so populated
#68
Whenever my car randomly decides to die completely while driving, i can say with certainty that i can still steer and brake...with a bit of manpower. That being said, it's never a fun experience and wouldn't do it on purpose haha
#70
Now not to say you're wrong.
I got a repetitive 36 on the highway w/ the 6mt on the G35 Coupe wheels but when I went to my racing wheels (only on the rears!!) even for a road trip I got 38 repetitively and 40 on the car's last adventure to Baton Rouge.

#4... oh man, this sounds dangerous. Plus, when you start your car it uses a good amount of gas/energy so it's almost a washout. And this theory onl works where there are hills, if you live in illinois or some other flatlands than #4 is not even a question.
I average 28 mpg on the street driving moderatly aggresive, and 33 on the highway.
Clean your iacv, cps, egr/tube, pcv, intake, throttle body yada yada... tires inflated and aligned (mine are slightly out of alignment). But turning your car off? You can damage your tranny if it doesn't catch just right and that's gonna cost a lot more than the gas you save.

Today was my first login to the org in over a month, and the first thing I see is one of my forums at the top of the page... I don't know whether this is a good thing or a bad thing... haha. Either way good to see that there are other people besides me that care about fuel economy.

Here in Montreal, a few gas stations were caught by price fixing scheme. Ultramar (one of the largest marketers and refiners of petroleum products in the country) was fined 1.8 million
That's petty cash considering they make billions.

The point is not that they are stealing $5 or $10 from me (although that reason alone would be enough to call them out). The point is that they are scamming people and think they can get away with it. If they can get away with stealing $10 from you, they'll try to steal $20, and then $30, and so on. I'm definitely not going to be a pushover and let them take advantage of me.
