I can't see any point to it.
Letting any car warm up a bit before driving it will extend the life of your drive train. Why? Because the motor oil and transmission fluid have time to come up to pressure and to establish a flow to all the moving parts before you put the engine and trans under load. It is especially important that the engine not be revved up immediately after the engine starts and before oil pressure and flow have been established. This foolish practice results in spun rod bearings.

Most of us will not wait a minute before dropping into gear and pulling out, but it is really better for the car if we do. You can spend a little time after starting the engine to adjust the mirrors, the seat, the radio, your seatbelt, etc. before dropping into gear. When it is really cold, start the car before you sweep off the snow and scrape the windshield. Whether you wait a minute or not, drive the car gently for the first few minutes until it warms up, and the car will pay you back with less wear and longer life.
Agreed... In Colorado we used to let the cars warm up a bit before driving... It was just too cold to crank up and fly away...

Here in FL it usually doesn't get that cold... But when it does get into the 20'*-40'* I do give the engine a change to warm a bit before I go anywhere

Thank you everyone for your responses. i appreciate your input. Well mostly

How is it that you think the oil in the crankcase, that has been flowing through your engine while you were driving it, is somehow any "fresher" when your car is idling? Elves do not show up while your car is idling and put fresh oil into your crankcase. This is the same oil that has been flowing throughout your engine picking up combustion contaminants, though your oil filter, into the crankcase, through the oil pump, and back through your engine.
Is this your way of calling me an idiot Bugsi? Very well done. I have always been a firm believer in bashing the guy who is trying to learn something. If you can't post anything with respect like everyone else can, please do not post to me.

I figured oil would go through the filter before heading to the block. so would it hurt to let some go through the block before i turn it off? I go up to my friends house with my PC to do some gaming. Generally i bring in my keyboard and mouse so i can let them know i am there and go out for my PC(and turn off my car). But they like to talk sometimes and it takes me a few minutes to go back out and turn off the car. I wanted to know if this was bad. I apologize if it seems that i am ignoring some universal logic. But I am not a gearhead. I am a PC technician. I'm using my best judgement. If you don't want to answer my stupid questions just tell me and i'll leave.

I ALWAYS warm up my car for a few minutes before i head anywhere. That i know i should do. And if i cared about gas i wouldn't have gotten a very large, super-charged car in Connecticut.(billboost can testify to that.)

And thank you MOS95B. I didn't know that was a ticketable offense. I would have never thought there would be a law like that. I am in a really good neiborhood on a dead end and no-one every really comes by, so i have never really worried much. That was out of left field and i appreciate it greatly.

Thank you all,
Rubix

Just so you understand a little further, they'd rather have you pay a fine than lose your car. It'* an offense for the reason I stated, it'* just asking to have the car stolen. Sometimes the "why" makes the law seem a bit more sensable...

Rubix, I want you to sincerely know that I in no way meant to call you or refer to you as an idiot, or otherwise belittle or denigrate you in any way, shape, or form, and I give to you a sincere apology that I can see is absolutely due.

My comment about elves was uncalled for, and meant in jest, to help illustrate a point, although I see that it does not necessarily read the way I intended it. Your question is completely legitimate, and I want you to know that is the only way I took it, despite wising off in the process of trying to give you my honest opinion and answer to your question.

I'm not a master-mechanic either, I don't know-it-all by any sense of the imagination. I hope you'll find the non-elven portion of my answer to be a genuine statement of my experience and thoughts on your topic, which is after all, what you were asking for.

I respect that you were well intentioned and I did not notice that you are new here. Some of us get pretty brutal with each other in our jesting, and I certainly don't want you to feel unwelcome on my account. If you do search my history, my posts are usually very straightforward and I do not have a history of bashing anyone. This is a tremendously great group, and I want you to feel as welcome as I did when I was new here too. Please accept my honest apology, and know that I'm sorry for my thoughtless choice of wording.

Letting your car idle after reaching your destination only uses more fuel. As for adding a bit of heat, this could be argued indefinately as to the fans coming on and the water pump circulating. There is some heat and the systems for dealing with it are in place and react about the same as sitting at a long stoplight.

Overall, the suggestion is to not let the car idle after you reach your destination unless you plan on hopping back in very soon.

Default Those darn elves

oh heck. i didn't know you were jokin bugsi. It is now forgotten, and i appreciate your input.

However, I do believe elves work on my car. But they are VERY evil elves. I find things broken, missing, or added to my car without explanation.
example....
1.Baby Carseat-What the fudge happened here?! I know i didn't put it there.And yet whenever i remove it is back in the next day. It'* elves or i'm cursed....
2.Bent car antenna-I believe one of those buggers drove my car through a car wash with the radio on! Can you believe that?! My sibblins told me it was my mom but i know better. A mom would NEVER hurt her child'* car now would she?
3.Sudden bursts of speed-I think they love to fiddle with the throttle line. They get a kick out of jerking it real hard. The passengers don't like to darn near eat their own Tongues. I always get in trouble for this.No one will believe my excuse. They say it'* a matter for the X-files. I don't remember putting my foot down THAT hard
4. 1/4 full gas tank- Oh now this one REALLY tears it. I go fill my tank and BAM! Gas disappears at a phenomenal rate overnight. They are gonna make me broke! :(

My uncle has a harley-davison bike with a bell on it. I asked him what the purpose of the bell was. I mean it'* not everyday you see a 250+lbs guy with a bell unless he is....well uh....you know. Anyway he told me it was for bike gremlins. He said bike gremlins cause all sorts of problems when your gone, and find a hiding spot when you come back. Well i guess they are attracted to the bells and they hide or sleep in them. Well when the bike gets goin down the road, the bumps make the bell ring. The gremlins can't stand the sound of the bell so they fall out and land on the road. I think it'* time i put a bell in my car(about 20 wouldn't look fruity right?). It'* that or i make an Anti-Elf System(AES? Crap, another acronym for me to remember). Where'* my heat seeking shotgun?

Thanks guys,
Rubix

I was really tempted to say something along the lines of "although the presence of elves sure would explain a lot of things that go wrong on cars."

I am also convinced that there really are elves that do things to our cars. Like turning the radio up really loud when you're away so when you turn on your car, you go deaf. How does that keep happening? And I'm with you on the disappearing gasoline too. We all know that HAS to be elves!

I just got my first speeding ticket in over ten years. I'm blaming the elves, but I don't think a judge will buy it, so I'm going to pay the ticket and do traffic school.

I let the car warm up before driving even if it'* a 90* day in July.

Rubix, you're only a few minutes east of me!

Hoping it'* OK to idle, I have to allow mine toi dle about 30 minutes with the trunk acess panel open to go anywhere. The selenoid valves to my suspension wont open or close when the temp goes below freezing. Most small chrome tanks for air hydraulics including mine dont have drain holes on the bottom and the only way to get rid of moisture in to do full body drops. Its not enough to keep the valves from freezing.
