wrong wrong bud. Diesel vehicle can idle forever; it will eat fraction of fuel.
Look at new/old benz/bmw taxis in Europe. They would idle for hours in cold weather, with fraction of the fuel.

30-60 secs to warm the car.

I usually use the 30 secs to clear the fog on my windshield.

Other than that, I usually go in 10 secs.

this is probably because I'm always late for stuff, so I don't idle.

Yup, diesels use very little fuel at idle. However it's still not good to idle a COLD diesel engine to warm it up, it would take forever to get up to temperature.

30s-1min... there's a big difference between "taking it easy" and "keeping low revs"

keeping low revs is useless if you're still bagging on it... knew someone who "warmed up" their car for 30 seconds, and then proceeded to bag on it UNTIL 3.5K... that's just... /palm

the only time i let my engine warm up is the day like today..

a thick icy layer on my windshield... i just start the engine and scape my windshield while having a smoke...

5 mins then im outta there

whats considered a low rpm when driving cold?
where i used to live i was on the hwy within 2m of leaving the house, so that was a constant 3000k+ rpm on a cold motor.

a diesel engine can idle damn near forever. altho, a diesel wont warm up from idling. and it will run like shit when its cold

Wrong
Go up north, diesels do not get turned off during the winter months. This does no harm to them it just adds to the hours on the meter. Not all diesels use glow plugs either. If you look under the hood of a diesel they do not have throttle bodies like on a gasoline engine some have flappers to prevent runaway situations but those only close when the engine over revs uncontrolably. They regulate engine speed through fuel enrichment so at idle a diesel engine burns barely anything.

on a cold day like today, i warm it up for the duration of ice scraping and did not rev it past 2k rpm till the engine is hot.

my cold idle is 1900 lol

when i start my 20 year old car, the rpm goes up to about 3k and when the goes down a couple hundred rpm, i start to go... which is usually 1min or less

same as mine. if i have the time to wait, i usually let it idle down to about 1200.

crap... i sat there warming up my car today for like 10+ minutes.

i park my car outside, and soooo much frost built up all over it. (the ice actually froze my doors shut, and i had to slightly pry it open). took over 10 minutes warming + scraping to remove the ice off my windows, and for the rear defroster to do anything.

if it wasnt for the ice blocking my view completely, i usually wouldnt warm up that long and drive it easy until car warms up a bit.

When it gets really cold ( like yesterday) my beater is basically frozen. I can barely open the door.. as there is ice inside between the keyhole and door. When I get it open, there is ice INSIDE my windshield also.. I must warm my car up for 5-10minutes before I can safely drive.

^ Same, I couldn't open my trunk for like 5-10 minutes to take out the ice scraper.

mine gradually drops from 1900ish to about 1600 then 1500 then 1200 then super awesomely warm would be 900-950rpm.

I usually warm up with remote start as I'm popping outta my elevator, gives me about 20 seconds or so to walk to my car, and then throw my lunch in, get in the car, setup all my car audio/gps etc... by that time 1900 becomes roughly 1500 and im out :D

this... but no elevator. :fuckyea:

I see, yah I thought that it might of been a bs fact (when i read it) because my 25 diesel trucks in my long haul fleet dont eat up that much fuel and they're on all the time in this weather cause theres a high chance they wont start up again in the cold. I know about the idle regulator thing as well I just didnt bother to mention it. I know for older diesels its different tho (especially pick up trucks).

lol elevator at your house... always wanted one

^ realistically.. not really...

haha. unless.. a four post hoist would be awesome. :fuckyea:

does anyone have frost building up inside of their windows?

Fuck, this thread comes up every winter. Remember it from last year, something about warm engine and cold tranny and then condensation/water in tranny...

I'll warm my truck up for 5 mins if I have to. Or the time it takes to scrape all the frost off of it.

I <3 idling.

Damn son, your car gets up to operating temp in 1 minute?

Ya, had that when I was in Whistler the last couple days.

Yup, mine does it too. It's because there were moisture inside your car somewhere. Can be from the carpet/mats and the humidity from your breath left in overnight.

Scraping the frost inside is like snowing on the dash. That's the only snow we can get for now. :\

The way I used to combat that with my old cars was to go for a 15-20 minute drive before I went to bed and kept the heat and a/c blasting the entire time. Minimal ice buildup on the outside in the morning, and the inside would be nice and dry.

Mind you, if you have a leak somewhere then you're hooped.

I get the "moisture absorbers" from Daiso for like 2 bucks each.

I stick them under my seats and they really do wonders especially when it rains.

But they wear out really fast cuz of the fact that its "Vancouver" and it rains 7 months out of the year.
