Your belief is well founded. It's illegal to "coast" in neutral.

You are simply wrong. You have no evidence to back that up.


No, you are wrong. It's idiotic to drive with an automatic trans equipped car and put it in neutral when going down hills. Prove it saves fuel. PROVE IT. And prove that constantly changing the transmission from drive to neutral won't prematurely wear it out. And prove that riding the brakes is good...

Gary, a manual trans is a bit different...

It's illegal in most jurisdictions and with good reason: lack of common sense of the average four-wheel jockey.


Mori strikes again!

Here's my evidence: when you drive down Pikes Peak, the park rangers pull you over have way and feel the brake rotors to make sure they are not overheated.

But hey, if you want to end up at the bottom of a ravine, be my guest.

Come on now, you can't be THAT dense can you? Once again I remind you we are talking about HILLS and NOT MOUNTAINS. If you can't tell the difference please turn in your license immediately.

Let me put it this way: If you're a dumb@ss, don't coast in neutral. Otherwise, if you have the brain capacity to control your vehicle there is NOTHING wrong with coasting down hill and lots of people agree with me. Not one person here has described a single incident of something bad happening, but lots of people admit to doing it.

I do it nearly every day for a mile, YES, that saves fuel, exactly 1/18th of a gallon, and my Jeep and transmission have more than 218,000 miles on them without any trans problems or a single dent. There's your proof.

Monkey man

You save 1/18th of a gallon, or $.22 ( figured at $4 gallon gas) a day, about $6.60 a month, $73 a year, that's if you make the drive everyday.

As angry as you seem to be getting with all the name calling and expletives, you'd think you were saving MONEY not money.

I think I am gonna keep doing what I am doing.

And I quote thee!

My concern is, anyone who reads this manure will try and do the same, and hit a long downhill stretch and ride their brakes...to their demise.

$73 a year from coasting down non steep hills...in a Jeep? EXACTLY 1/18th of a tank?

I'm not so sure that the Scan Gauge really knows that, as it appears to determine it's fuel flow information on either MAP or MAF sensor readings, which will not change if the fuel is cut off.

Gentlemen (sigh) ..everyone here is imprinting their view of others upon what they're giving as advice.

Let he who has not taken managed "risks" cast the first stone.

Anyone here exceeded a speed limit?
Impeded traffic by going the speed limit when prevailing conditions compelled "the herd" to want to go faster?
"Enjoyed" a good back road with a good handling car?
Engaged in offroad activities that included off camber ascents/descents?
Experienced a planned 4 wheel drift?
etc..etc..etc..

In short "elective behaviors that aren't text book sensible due to the broad span of skills and interpretation of the practice"? Sure you have and you did them thinking that you knew what you were doing ...and if you continued to do them, you eventually knew what you were doing.

There are many here that own Sunday drivers that produce 500rwhp and "exercise" them routinely on the public streets/roads/highways. By the tone of this thread ..you're all potential homicidal and suicidal maniacs ..or fools ..or at least foolish.

How would this satisfy everyone in "getting their pound of flesh"?:

Although not recommended due to (fill in your blank of ojection) here's what my take is on the technical aspects of what you describe. Keep in mind that there are potential issues if (fill in your blank of objection) is/are encountered, and always exercise sensible caution when doing this. No assurance of sensibility (merchantability for devices) for any outcome is expressed or implied in this opinion.

I have no cause to do this, myself ..but there are many things that I DO that no one else sees sense in. Whether I find another's actions sensible or not ...and/or regardless of how many POTENTIAL liabilities that I can configure in my own version of "what if" ...and regardless of how many times I've dropped an object on a 3000 square foot barren floor ..only to have it find the single 3 square inch drain ... others mileage may vary.

Just because you own a bb gun ..doesn't mean that you'll shoot your eye out kid.

Oh, there's a detent on mine, too. But it's a pretty mild detent. I've had floor-shift automatics where you either have to push a button to go from N to R, or had to zig the shifter around a zag in the selector path. On this one, I have a feeling I'd miss that detent, especially if I were in a hurry.

If I still lived where there were hills I could descend without traffic around me, I might try it, but I don't live in those conditions (more's the pity). So I think I'd do best to slow down a little to save some gas.

To each his own, and his own experimentation. Be careful!
