Me neither.

How long do you guys let your cars idle in the morning? Chicago weather is dropping temp and I’m just wondering if I’m helping or doing more harm by letting it idle for 5mins or so. I’d always thought that it helps bring everything up to temp, but I’ve been wrong before

About 30 seconds at most. I just shift at low RPMs until it's warm.

Those were the olden days, with carburated cars. Now, like BMWCurves stated, you just let it warm for a short time.

The car warms up a lot faster by driving it. Idling it is just wearing the motor unnecessarily.

Thanks so much guys, that’s what I was beginning to figure out, good to have some other input than my brothers dismissive mechanic talk(“yea it can do damage but it’s whatever”)

I only idle mine for a few seconds and then drive it gently until it reaches normal temperature but, for example, my wife likes to remote start her car ('12 Grand Cherokee) so the interior / seats warm up so involuntarily the engine is probably getting unnecessary wear.

The little HK speaker cover on the door had some sort of residue on it which I tried to wipe down. I think it exposed the metal. Is this cover replaceable, or how would I go about trying to paint it?
