Watch out for that "non-gaseous extra gasoline".
Or don't worry about it, like me. I rolled as soon as I started up and my engine and interior didn't warm up faster. Besides, I was idling down the road; the RPM were almost the same as warming up in my driveway.
The man has a valid point - fuel injected following a cold start does not vaporize as quickly, which results in extra 'liquid' gasoline in the cylinder. If you want to read a raft of technical papers on it, try searching on 'GDI engine cold start fuel vaporization'.Watch out for that "non-gaseous extra gasoline".
That's why more and more governments are passing laws against excessive idling.
Governments are mostly interested in looking good. Our cars burn cleanly. The emissions difference between idling and driving is minimal.
I didn't see any difference in how quickly my engine got up to operating temperature, idling or motoring down the road conservatively. Now, if I put the go pedal down right away, that would warm things up faster. But I won't abuse the engine just to get it to warm up faster just to vaporize the gas better/quicker.
You're missing the point. A car idling is getting zero miles per gallon, producing emissions, and going nowhere. When you're finished idling, now you have to burn more fuel to get where you are going.
You may not notice it, but there is a difference. The car 'driven conservatively' is still doing work, and will always warm up faster than a car idling.
Not missing the point: How is my gas mileage anyone else's concern but my own? If I want to get crap average mpg and spare my cold engine, that's my choice. The environment doesn't care if I am rolling or sitting. Earth has plenty of fossil fuel reserves.
I am going to do keep doing this, and leave off idling in the driveway. For now. I may change my mind again (not merely the privilege of women
).
The point is you said 'the emissions difference between idling and driving is minimal'. The problem is you aren't going anywhere when idling - so your trip to the grocery store actually generates significantly more in the way of emissions, when you travel the same distance, but spend time idling beforehand. Yes, the environment does 'care' whether you, and everyone else, are rolling or sitting.
I deleted my knee jerk response. This is heading into political agenda territory. End of discussion by me.The point is you said 'the emissions difference between idling and driving is minimal'.

That is why governments are cracking down on idling time, not because it 'looks good'. Idling = zero miles per gallon, and infinite emissions/mile, something most governments are making an effort to address.
Back to your regularly scheduled programming. AWD and snow tires, anyone?
OK.... We're getting some serious winter now after below average snow so far. Took the #1 daughter to birthday dinner after work. Probably 4 in. of snow in 4 hours. Main roads were bad with the polished snow and all the knuckleheads who can't be bothered to pay attention. Got on to the side roads a few miles from home. Put it in Sport and turned TC off. The snow tires (Michelin Ice-X) performed great. Plenty of grip to inspire confidence, but on-demand slip to power out of the oversteer. What fun to steer with the rear wheels and throttle! Who needs RWD and dry roads!?Back to your regularly scheduled programming. AWD and snow tires, anyone?
Damn sexy wheels
Yes, nice looking wheels! If you don't mind my askin'... how much to they get for a set of those?
Nice choice. BTW - you're going to love those Michelin X-Ice's.
Looks like those will be a great winter rim. No exposed machined surfaces, a nice open design that should help in keeping clean, and a wide, angled flange to keep the snow and such out. And it'a a looker as well!

Thanks - that's a good (and recent) reference, which nicely covers the cold FI engine issue with poor gasoline vaporization. The article also had a nice close, quoting a respected auto manufacturer renowned for their winter performance testing.
Apologies, @kaius. I did think about my use of humor and decided (poorly) to go ahead. I wasn't even thinking of the language and resulting cultural frictions. I understood your terminology, even though the entire subject of unburned (extra) gasses is new to me.
Ah, missed that bit. So much for the "walking manual" appellation. recently given to me.
I'm in the central portion of the state of Illinois. The absolute last day of the year I will wait to mount my winter wheels and tires is November 12th. We almost never have snow before then, but temps can change wildly. I won't remove them for summers until April 15th. My first day of a groundskeeping job in high school was spent shoveling the 5 inches of snow that had dropped the night before.
