Turbo's need warm up and cool down time. That would be all the case you need. Will running a turbo cold kill it immediately? No, but it will shorten it's life. Not as much as not letting the turbo cool down, but it will still shorten it nontheless. I try to let it idle down before I take off, but that's not always the case. I definately don't stomp it until it warms up a bit. Usually about 10 miles or so if it's not below 0.

she has the idi no turbo tho

 

When I was stationed in Germany I was told it was illegal to idle an engine to warm it up. When I complained to my German landlord (an engineer) he gave a great reason, aside from pollution. He said when the engine is cold it runs rich and the extra "splash" of fuel over the cylinders washes lubricant away. You really want to warm the engine up as quickly AND gently as possible. I start up my truck, adjust the radio, put on my belt and put my cell in the cup holder. After that I put it in drive and get on down the road.

 

I let mine warm up 'till the ice is melted off the windows - I just really hate scraping !

 

Don't know about anywhere else but it's actually illegal to have an unattended vehicle running in my town. Not sure if it's a state law or city ordinance, could be city because we have a max security penitentiary on the edge of town. I don't personally know of anybody ever being ticketed for it but have been around when the police are "educating" people about it.

 

sucks to live in a city where they have to pass laws to keep thugs from stealing your truck, I leave my trucking running just about every time I go to the store and if I don't I leave the keys in it and never worry about it

 

For all I know it could be state law regarding safety.

 

well I've never heard of that being the case here but I live it Texas so that might be the difference lol

 

Colorado has the same law, as does Massachusetts. Never enforced. Its supposed to be about pollutants...Have they been on a Massachusetts highway?

Now, we are on a thread about trucks with 5 Liter engines and such. The amount of pollution put out my my 1.6L V4 when it is warming for a few minutes on a cold day is not really doing that much.

A cold motor's components, the Alt, Starter, etc, will not like being run full force right after a VERY cold start (under 20 degrees). This is PURELY physical, and means run idle for maybe 30 seconds. Start and go is fine over 20 degrees or so.
