Idling is bad for your engine..

[mazdamazda]

ako kahit masama pa yang pag-iidle ng engine pagka-start, gagawin ko pa rin yan for at least 1 to 1.5 minute.

Check your car's manual... most manufacturers recommend just a 15 second "warm-up" before driving off.

Ano bang masisira kung naka-idle, at least the engine is running on its lowest rpm habang umiikot yong langis sa buong makina. di naman kailangang hintayin na tumaas yong temp, basta masiguro lang na well protected na lahat ng parts ng makina bago i-rev ng up to 2000 rpm.

Idling a cold engine can lead to a faster carbon buildup in your engine. A combination of a high fuel-air mix at idle plus a cold engine isn't good for the environment also.

If you concern is about better (or overkill) protection - switch to semi or fully synthetic motor oils. A second after staring up your engine your motor oil would already have lubricated already all moving parts properly.

ganyan kasi yong neighbor ko, halos kaka-start lang takbo agad, at maririnig mo talaga yong ingay ng makina habang umaalis and yong car is only over a year old.

As I've said - the proper warm-up technique for a cold engine is a 10-15 second idling period then drive slowly for the first few kilometers / minutes.

I think the best thing to do is to follow THE manual. Meron din kasing ibang sasakyan like the classic Tamaraw FX na kailangang tlgang iwarm up muna bago patakbuhin dahil walang gagawin yun kundi pipiyok nang pipiyok kung pinaandar nang malamig.

thanks to this thread, i learned a lot. i didn't know that idling my car 3 to 5 minutes was an overkill. i thought it is really needed hehehe. thanks to all of your expert opinions.

pag itinakbo ko ang car ko after 15 seconds warm-up, it wont upshift for the first couple of gears till it reaches 3000rpm. Like what you said, kailangan dahan-dahan lang at first which means lower rpm. There's nothing wrong with the car, that's just how it works after cold start, to warm-up the cat quickly.

^^ and considering you're in London, it's a colder climate compared to Manila. So idling will have to be longer than 15 seconds to get to operating temp.

used to do this on our old DX.
pero now, hindi na. basta gentle driving lang until the engine warms up to the normal temp.

Exaclty 10 years ago, Al S. Mendoza of the Inquirer motoring section noted that "the best way to warm-up your car is in gear"; this way all your moving parts that need lube will get lubed altogether. This goes especially for the engine of modern cars with electronic engine management systems.

In regards that long idling can inflict harm to an engine, i don't believe that it can, at least not with todays engines. I do believe that it can be harmful if your engines cooling system is not 100% performing. In my experience, ang daming nag-rereklamo na their temp meter goes up whenever they idle long or get stuck in traffic. A closer look revealed that its either the driver didnt check the coolant level of the radiator or simply does not practice periodically draining the dirty fluids and put in a fresh batch.

I like to think that idling your engine varies from country or climate. Im sure yung mga taga Bagiuo would like to warm-up a bit longer for optimal performance lalo na sa area nila where you find lota hills that need ample torque. But as form of good measure, never race a cold engine.

sa manual ko, nakalagay, warm-up by driving. Tapos may section din na never let a cold engine idle for more than 10 mins, and no more than 20 mins for a normal operating temp engine.

[userfriendly]

Best talaga follow your manual. I normally just start the car wait 10 seconds or so and drive slowly until the car reaches normal operating temp. So far so good.

I belive that most if not all of us will agree that idling is bad for the wallet.

Picard,
If it is your Altis, you can actually start-up and go.
