How bad is 20min plus idle?

8500RPM · 01-28-2018, 05:30 PM

Hey Guys,

Just got my 2012 Space Gray E92 M3 and im in love! I have a concern that I need guidance on...

Sometimes I need to leave the motor running for 20-30min at a time. Done this about 5 times already. Is it as bad as I think it is for my motor? Does it not do any harm as long as oil and water temps in check?

Idling a modern engine is fine.

At our mine site, from the month of October to April, vehicles run pretty much continuously.

Banana Hammock · 01-28-2018, 06:54 PM

20 minutes is a bit much.

1MOREMOD · 01-28-2018, 07:03 PM

Why

swhat · 01-28-2018, 07:07 PM

20 mins idle is less stress than 20 mins at the tracks....so why care?

Thik · 01-28-2018, 07:29 PM

Turn the car off. Problem solved.

roastbeef · 01-28-2018, 07:31 PM

it isn't the end of the world. now i'm curious why you can't turn it off.

Just let it sit idle for 45 seconds after you do a cold start, then drive off
Just let it sit idle for 5 minutes after a drive.

Why let it idle after driving?

Well I came from a turbo car, and one of the things you should do is let the car idle for a bit to have the oil go through and cool things down.

I do the same with my M3 just a force of habit

roastbeef · 01-28-2018, 08:32 PM

i tend to let it idle for about 15-20 seconds after i park to let it "settle down." no rational reason, i'm just a little weird.

What's wrong with steamy windows?

TrAcK TRaP · 01-30-2018, 08:24 AM

I don't think it should be a problem. I had a modded 335i before my M. One day I left the car running from 7 am to 4.30 pm. Damn Comfort access I had to switch car in a hurry and forgot to turn it off stupid me and didn't have any problem beside waste of gas :/

Need pics of co worker to confirm that rod bearings are still good.
