can rolling damage car

[dempseyblade]

I've only been driving for a month or two now and I have git into the habit of being in neutral whenever possible, even sometimes if i am going about 30+mph. I've been told it's a bad thing but what damage can this do and is it actually bad?

(btw i dno why i do it, just a bad habit):wacko:

Dont damage your car,just wastes petrol

i reckon i thought it would save petrol being in neutral. heh, thankyou though:y:

[GJF47]

Probably just wear out the brakes quicker than changing down using engine braking. I've got a habit of doing it when lights are red down the road, I'll just roll up in neutral.

How exactly are you wasting petrol by having the car in neutral (and thus lower rpm) than having it in gear and having higher rpm (+engine braking)

[Mieran]

Will use no petrol if you leave it in gear (depends on rpm) will use petrol is you take it out of gear.

[Prickle]

i do it now again, cant say i notice a difference..

Leaving it in gear means no (very little on older cars) fuel is injected into the engine.

Taking it out of gears means fuel is injected otherwise the engine would stall. Your car is basically idle while moving.

Think that keeping the car in gear when you let you foot off the throttle as long as rpm is high enough cuts so most of the fuel coming out of the injectors, As the the motion of the wheels turning keeps the engine turning over, Then when the rpm drops to just over 1000 I think the injectors kick back in to keep the engine running, Were as if was in neutral would have to fuel all the time to keep the engine idling, Is something along those lines anyways sure someone could put it better than I did :)

[blackie_2k5]

its not just wasting fuel, its dangerous tbh, you have alot less control of a car out of gear, especially when braking

[dempseyblade]

Thanks guys, I will try my best to break this habit.

[Carl-h]

Very bad habit, one you should try and get out of tbh. Makes me laugh when people think it saves fuel few of my mates have done it. When you learn to plan ahead you can drive literally only Using your brakes for the last 5-10mph when coming to a complete stop. Just shut off well in advance and once your used to it you can get it pretty accurate. Saves a load of fuel too.

best brake it before the ice comes in or you will 100% no doubt right off your car

and thats a promise

Just get down to your local mcdees and get the trays out for some practice before the white stuff comes. Girls will be making ice cubes over your drifts.

[LSOfreak]

so what about putting the clutch down when you get to a hill and just rolling for a mile or 2? does that waste or save fuel?

forgot to add that bit! :y:

waste, and holding clutch in is worse for your clutch cable and thrust bearing

Wastes fuel. Just pop it in top as long as your doing 35plus and then you'll have the least engine braking but will use no fuel. Obviously in third you would slow down much quicker so for slowing down use the highest gear you can, aiming to keep your revs above 1500 ish.

[LSOfreak]

interesting... never knew that, ive always assumed the lower revs (coasting) will use less fuel. to be fair though, ive been coasting down hills for years and have never noticed anything breaking/wearing quicker than usual

how would you know if youve been doing it years :geek:

[LSOfreak]

from when i drive other cars. nothing seems to have worn out of the ordinary

[Manu]

waste of petrol and waste of your brakes.

[Mochachino]

As said it wastes fuel. I also hate the feeling when im a passenger and someone goes into nuetral an rolls up to a stop, I prefer the feeling of engine breaking than the feeling you are rolling away and then the feeling braking.

[Carl-h]

Yeah I hate the feeling of coasting. Mate at college never used to come down the gears, top gear then clutch in and brake to a stop and put it in first. Always felt horrible.

[LSOfreak]

yeah i use engine braking all the time. feels weird using your brakes to stop from a high speed.

[KamRacing]

At idle most engines run slightly richer to help stop you stalling if you fluff things. Theres really no point in coasting at all in a modern car. Its a silly habit giving you less control of your vehicle.

[Simon0014]

Bad habit as you have less control of the car...what if you need to quickly accelerate to get out of danger. You can't just put your foot down...that split second is the difference between crashing.

[D--R--E--W]

My trip computer goes higher mpg when coasting than it does going downhill in 6th

[TechnoBoy1]

I noticed a big difference when I was doing my lessons the mpg would drop if I coasted and would stay about the same If i just used engine braking but cant notice any difference in my saxo ( probably because I have no mpg display !)

[Jonny52002]

From what I've heard coasting in neautral uses more fuel then running off throttle in gear. Going up to red lights I go down all the gears blipping the accelerator for each change to match the engine speed an let the engine brake first before using the brakes if possible.

[Prickle]

.what if you need to quickly accelerate to get out of danger. g.

you dip the clutch in and select the correct gear.

[Simon0014]

You've just taken my sentance out of context....like i said before those few seconds doing that takes makes a difference...

nah i know what you're saying man.

Experienced this yesterday actually lol.

There is a steep dip near mine (go up one side and down the other with no flat in between) anyway there is potholes and usually a couple cars on one side.

I was coming down the other where the road isn't blocked by cars etc, and coming the other way there was a car on my side of the road. It was late in the evening and going the way he was going the sun sets right in your eyes and you can barely see. He continued on my side of the road I skidded to a stop, realised he still hadn't seen me so lifted the clutch and mounted the curb. He quickly swerved at the last second, if I didn't move he would have hit me.

Putting the car into 1st (it was already in 2nd as theres a junction just before the dip) would have taken probably enough time for him to crash into me. Accident wouldn't have been fatal or caused any serious injuries as he was going no more than 20 but you get the idea.

dont go through the box unless you need to slow down quickly, block change, saves you more fuel, you use more fuel everytime you change a gear ;)

[MiniGibbo]

As said above a few times, keep it in gear and dont coast like a loser..

[wassy78]

Well that's bugged me up lol when low on petrol I always take it out of gear and roll to save petrol cos thought it did lol :( thanks

[Stevebear]

i used to cruise in neutral when first passed. One day was showing off to a mate and took the ignition key out. How we laughed as I bumped up the kerb and took out half a hedge cos the steering locked engaged.........

That must be a rinse..

If that actully happened, genuine LOL.

[logic_guy]

I think that in France they are thought to approach traffic lights in Netrual.

How can engine breaking 'Save You Money' as such?

Clutch wears out quicker, higher RPM so that means more wear and tear etc.

Does anyone sit with their foot on the clutch at traffic lights? This really annoys the hell out of me. I sit in Neutral with the handbreak up. Its safer and not going to wear out the releasing bearing :cool:

same! lol

[CraigLovelock]

Havent read 3 pages, but dont see how you can 'roll' all the time.

Saying that, i used to when learning, havent done it since.
