Idling vs Turning Off the Engine [Merged]

**ravelcop** · August 17th, 2005 05:26 PM

While waiting in the car, when can you say that it is fuel-saving to turn-off your engine than leave it idled? Narinig ko kase sa TV na aksaya sa fuel when you keep starting your engine. Meron bang specific duration na it is better to leave it idled instead of turning it off and on back again?

if you have to wait more than 5-10 mins.

If you have a turbo engine, you really need to idle for a minute or two (sometimes longer). Else, your engine might die on you, one of these days. And, that's a lot more expensive than saving on a few ml of fuel.

pagnaipit ka sa buhos style na traffic ... patayin mo na makina mo .. tapos hanap ka ng nagtitinda ng mani sa labas ..

AFAIK, the fuel consumed by turning on your engine = 2 minutes of idling your engine

so, if you are waiting for 3 minutes or more - it is best to just turn off your engine.

yan din ang sabi ng mga car talk shows na naririnig ko. the only thing is, i guess it would depend on the car, right? wouldn't a hummer h2 consume more fuel at idle than a civic cx, and therefore should be shut off sooner?

M54, dependent nga sa type ng car.

kung less than 5 minutes ka lang maghihintay.. wag mo na patayin. hindi rin kasi maganda ung lagi mong iniistart ung makina..

kung 5 to 10 or more..patayin mo na para tipid gas tapos labas ka na ng kotse para di ka maiinitan at para mas safe kesa maghintay ka sa loob ng kotse.

well... the h2 will also consume MORE fuel than a civic when starting it up right? ;)

why would a start use more fuel?

baka para sa cold starts lang yan?

i don't see how a hot start will use up more fuel... gas-electric hybrids routinely shut off the gas engine the moment zero loads are encoutnered
