Engine Idle... Bad for my car?
Hey got a good question for you guys. I drive about a half hour to my school everyday. Good spots are hard to find, so I usually arrive about a half-hour early. It's cold, so in my old car, I would just leave the engine running and the heat on. I've heard engine idling is bad for the car, so up till now I've taken good care of my TSX and turned it off. Now, what I want to know is what exactly is bad about idling the engine? Is it just the waste of gas or is there something more? I think you guys know what I wanna know. Thanks, love my car =)

for how long a period of time are we talking about...?
Personally When its cold out and we have a call at the FD, most of us do leave our cars running in the parking lot...myself included

Im not talking about warming up the engine. I am talking about when I arrive at my destination early. It won't be stolen cuz I will be in it.

A few bad things come to mind when idling an engine, especially during cold start.
1. Moisture inside the crankcase - During cold start-up and before engine temp is up to operation temp, moisture build-up inside the crankcase will mix with the engine oil and diluting it over time. The moisture will desipate itself when the engine is hot. That's why driving short trips, long idle require more frequent oil changes.
2. Moisture in the exhaust system - Moisture is formed as part of the normal combustion process. Ever notice the tail pipe of the car in front of you spilling out water? Imagine this moisture build-up in the exhaust pipes and mufflers, causing the rust-out problem. The problem is going to happen anyway but more so with idling engines, just like moisture in oil.
3. Foul spark plugs - The stock plugs are designed for certain heat range and operation condition. If the engine is always idling, the plugs might to too cold to burn off carbon deposit causing foul plugs over time. Minor foul plugs can be self-cleaned by running the engine at higher rpm.

In this guy's case, he's not talking about a cold-start idle. So most of the bad-ness of it is eliminated. I think the worst part is that you're wasting a heck of a lot of gas doing that.... Why not just turn the car off and go inside and wait?

that's what i was wondering. why don't you just go inside. or is it closed till a certain time. and for those who are thinking he's trying to ask about a cold start, he's not. he's asking about idling his engine after he arrives as his destination.
