well then im in a delima because i can do the speed limit in neutral but i have to give it a little gas in 5th lol
nutshell: the more your left foot plays with the pedal, the more the clutch and tob wear out
put it in gear and leave it there
coast in gear when decelerating
put it in neutral at long stops
don't powershift the b***h like speed racer. in fact, quit watching speed racer and F&F all together. those actors shift gears like 15 times between 0-45mph

We are on the same page. If others just take time to think about the ideas presented in this thread, more should eventually jump on board.if you put it in 5th (or any gear) and coast all the way down the hill you will use no fuel. this is what is trying to be explained, that when youre in gear and coasting your engine gets no fuel, hence why it slows down. it may still sound like its firing but its actually not
when you coast down the hill in neutral your engine uses fuel to stay idling. it's a small amount, but it adds up over time
x2This engages the throw out bearing and will wear it out prematurely.
Slowing down with the transmission in gear and throttle closed saves gas because the
ECU goes into fuel cut-off mode. Slowing down in neutral uses more gas because the engine idles, which uses some gas.
Oh... So the car is able to stay on due to magic?Incorrect. When you are decelerating in gear at closed throttle, the ECU goes into fuel cut off mode, which uses no gas.
Engine braking saves gas.
Damn. I even explained this early in this thread. The motion of the car keeps the car on.Oh... So the car is able to stay on due to magic?
When you throw your car in neutral, regardless if it's moving or not. It has to IDLE to keep the car on. When the car is idling, fuel cut off is past the RPM, to where it HAS to use gas to keep it on.i was getting at the point of your using gas as long as your car is running. sitting still driving.. no matter what its using fuel.
you can decelerate in neutral. and eventually you'll come to a stop. but no matter what since the car is still running. your consuming fuel.
and how does engine braking save gas? id like to know since were on the subject.
Damn. I even explained this early in this thread. The motion of the car keeps the car on.
Here's a scenario....
You are driving on 5th gear going about 45 mph. About half a mile from you, you noticed the light turned red. To save gas, keep it on 5th gear and don't throw it in neutral. Feel free to brake, but throw it in neutral before you reach at a dead stop and stall.
Keeping it in gear while the car is in motion (aka engine braking), will keep the car on without using a lick of gas. Fuel cut off stays in effect until a certain low RPM (before it stalls)...that RPM is the perfect time to change gears to neutral.
If you feel like the car is decelerating too much when your coasting. Keep it on 5th gear, it has the least amount of engine braking. Then downshift if you need to accelerate. Using this method saves a very significant amount. It's the very sole reason why manual cars get better MPG than automatic cars. Most automatic cars has to idle no matter what, since the transmission isn't connected to the engine when decelerating.
So your saying stay in 5th gear till your aboutt o stall? dont downsift accordingly? 5th, to 4rth to 3rth to 2nd to adjust to your speed? u explained it as if you would stay in 5th gear till youre going about 10mph
You don't necessarily have to, but you can. Downshifting gears will cause more engine braking, which isn't desirable to some people. But if you stay in 5th, just throw it in neutral before it stalls. Which ever works for you. Like explained earlier, fuel cut off is only when it's above a certain RPM, so it will start throwing some fuel in, when it gets below that. Your car will only stall, when it's really near a dead stop, even on 5th gear.So your saying stay in 5th gear till your aboutt o stall? dont downsift accordingly? 5th, to 4rth to 3rth to 2nd to adjust to your speed? u explained it as if you would stay in 5th gear till youre going about 10mph
Yes, when the transmission isn't engaged with the engine; The engine will idle, and it will use gas.thats not what I meant fwd... What he was saying is when the car idles it uses no gas. Not just rolling. But rolling would also be considered idling as well. You can roll in an automatic as well, its the same thing as idling.
When the transmission isn't engaged the engine will see no more rpm's then are needed for idling. There is no "motion" that will keep the car on. The half-shafts are attached to the transmission, not the engine itself. So... how is "motion" going to keep the car going?
Absolutely, it's magic that keeps a one-ton moving car in motion, not the well known force of physics commonly referred to as momentum.Oh... So the car is able to stay on due to magic?
Nobody here wants to take away your choice to do what you want.i used to prefer the feeling of coasting to a stop in neutral over coasting to a stop in gear where it feels like the car is pulling back. If my gas ran out 5 miles sooner who cares.
You are clearly having difficulties reading and understanding the English language. You have made false statements above. Please provide examples of anything that I have written in my posts where I say an idling engine won't use gas.thats not what I meant fwd... What he was saying is when the car idles it uses no gas. Not just rolling. But rolling would also be considered idling as well. You can roll in an automatic as well, its the same thing as idling.

does this go for automatic cars as well? (i apologize if this is a n00b question)Slowing down with the transmission in gear and throttle closed saves gas because the ECU goes into fuel cut-off mode. Slowing down in neutral uses more gas because the engine idles, which uses some gas.
