modern engines warm up quicker and last longer if not allowed to idle cold.Source? Another one for the urban myths thread me finks.
try reading the drivers manual for the next truck you drive, or even the one for your own car. I’ll quote from mine if you want when I get home next weekend
Well i dont let mine idle to long, not just because of other driver’s, but also when parked in Industrial Estates,i think about local residents.
Also my Twingo will set its own idle speed when you start the engine from cold, and when its winter time thats usualy about 1000rpm, but after about 3 or 4 minutes you can tap the throttle and the revs will drop to normal idle, and your ready to go, and thats when its cold, in the summer it goes straight to normal idle 600rpm, so its ready to rock and roll,
The only time that i get narced when someone lets their motor idle for ages, is when the fumes start to invade your cab 
We use Vemis systems in our trucks and never idle the engine at all. I have recently finished an economical driving course and Scania and Daf both teach there is no need to warm up or unnecessarily idle a modern truck EVER. There is no need to drive it gently either just keep it in the green as you always Should (Maximum power transmission is the same between 10-15,000 rpm above 15,000 you do not develop anymore power at all period 
) the only time you should raise the revs to make the exhaust brake more efficient ( between 20-25,000) burning no fuel whilst exhaust braking.The engine will last longer, you burn less fuel saving you or your boss money (better job security due to savings made) and of course your being kinder to our environment.
However you always you should expect noise at the truckstops as educating drivers takes time, and even with the correct education some drivers still remain ignorant [zb]s by choice.

As quiet as possible . Never leave it running . If i can i,ll get the speed up and then switch off and freewheel to a halt if i,m going in between overnighters in the services .
That sounds like a dangerous thing to do, your power steering would not be working with the engine not running, sounds ■■■■■■■ stupid to me.
our erfs will only idle for 3 mins then cut out [ some kind of device fitted to them
anyway never mind idling what about drivers turning off there reversing bleepers , i thought there was a law you had to turn them off at night or doesnt it apply to truck parks

I think you mean hundreds not thousands.
If you managed to get your truck to rev to 25’000 you would end up with about 6 pistons stuck in your backside 
Racebikes only rev to about 17’000

You’re supposed to switch them of in built up areas between 11pm and 7am, same as sounding your horn. Truckstops arent generally built up areas. Our 7.5t’s have button to kill the bleeper, none of our larger trucks have any aparent way of disabling it.

Look in almost any vehicle handbook.
Try the Volvo one, you’ll see it in there.

Try putting the rear fog light(s) on, that often kills the reversing bleeper if there is no off switch.

our erfs have a rocker switch above you to turn of reversing bleeper, i thought most trucks would have to have them or how would you turn them off in a built up area 
mind dont suppose it matters as you wouldnt hear them with the likes of rob k racing there engines away
will try the fog lamp thing.
It might be our 18’s dont have a cutout as they dont expect us to use them in town in the middle of the night.
put the headlights on,that will stop the bleeping,it did on my MAN and does on my Merc now

Obviously you also don’t realise that modern engines don’t need to be warmed up.
Perhaps you should go read the handbook. Take particular note of what it says about turbos.

I’ve never seen it mentioned in any hand book. /quote]
Big sticker on the windscreen of the lorry I drive stating that the engine should be idled for at least one minute at the beginning and the end of a journey to allow the turbo to be lubricated at the start and to cool at the end of the journey.
…and then there’s a company sticker saying not to idle for more than a minute…

agreed turbos need to be lubricated, however, slow driving also counts towards your idle time, slow as in how you should be pulling in or out of a truck park.
A couple of minutes is all it takes to get the oil to the turbo, not 10 plus minutes
