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)

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

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)

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

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

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

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

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.

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.

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?

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.

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
