Just remember, every time you're idling you're getting exactly 0mpg. And a cold engine is burning the most fuel. The best way to heat up a vehicle is by driving it. Sometimes it sucks to be cold and I'll admit if it's approaching single digits I'll let my car idle to warm up. But yeah, it's horrible for your mpg!

Of course, if you live in those parts of the NE where morning conditions are just perfect to keep your windshield completely fogged up, you get stuck waiting until the defrost air has warmed up enough to at least let you see clearly. I hate that, sitting there wasting fuel, but I'm a bit odd that way, about wanting to actually be able to see what's in front of me when I pull out (others I pass on the road, often apparently are not so concerned).
 
I happen to agree, I have to have the windows so i can see out of them and will gladly waste the fuel to get the ice off of them. I usually start the car and remove the snow and ice then drive off. It's no good if I get into an accident at the first intersection.
Worse still are the SUV's that NEVER clean their roofs and they have 12 inches of snow almost always iced over on the top and when that comes off at highway speeds it's enough to shatter a windshield!
Having an SUV means never having to drive responsibly I guess.

In my post about starting and driving, I never meant to suggest that you should do so without first having clear windows. I'm fortunate enough to have a garage and so I don't need to deal with snow and/or frost removal in the mornings, however, it isn't at all uncommon for me to have to deal with those things when leaving work. In that case, yes, I do start the car, turn on all of the defrosters full bore, and then go to work on the glass.
 
I too have a "thing" about driving when I cannot see further than the dashboard.
 
Best Regards,

Does the light visicoty oil make warn up time unimportant? I usually wait until closed loop operation starts, generally around 75 deg coolant temp.

First off, you will not see real break in till app 10,000 miles.
 
While I did start to get 35-40 mpg from the get go (38-42 mpg daily commute now), the conditions overall have been a. consistent b. much less demanding than I perceive yours to be. c. by default, driving within the break in parameters
 
Secondly, gassers by design do NOT have a certain mpg for all reasons and seasons. Indeed a certain VARIANCE is the rule, NOT the exception. The problem of course is when one thinks the lack of variance should be the rule and not the exception.
 
If you read the fine print on YOUR new car sticker, there is a huge ( range) variance, even as they state the EPA city/highway, which in itself shows variance. So for example, mine says EPA 29 C/38 H. The fine print goes on to say: between 24-34 city and 32-44 highway. The "for comparison shopping" fine print drones on to say: COMPACT 13-48 city, 19-51 highway. So it being new, not only is the vehicle breaking in (and for my .02 cents I did make a concerted effort to break the car in correctly) ,experiencing winter conditions, YOU are getting used to the car and (maybe/maybe not) making adjustments.
 
So I would concentrate on break in (and your adjustments to it). Good break in can be important to longevity (my goal is app 450,000 miles) One thing I would do, oxymoronically is to rev the engine closer to red line (75% of red line if you are not comfortable with the concept) every so often when you can. I would also just start the vehicle and go as soon as possible after start up. Whether you make driving adjustments is really up to you, but it is usually the single most important factor once you understand your particular vehicle.

I know, was just posting for fun. And, this morning was one of "those" - cold and damp enough that I could not towel the window clear and drive off. Instead I did have to wait at least 5 minutes or so before the defrost was blowing warm enough to do the trick.
 
Of course, the electrical rear window defrost did it's job in less then a minute, but I didn't want a stiff neck from driving backwards for the first mile or so, so I waited

To state the obvious, the overwhelming majority of participants in this poll (77.02%) get between 24 to 36 mpg. The mode (21.27%) get 27 to 30 mpg.

Of course there's that one dude that claims in excess of 53 mpg and over 700 miles on one tank. I called "wind aided" on that tank of fuel and he (and others) got upset with me. :-/

Oh GEEZ! I hope that person isn't one of THOSE that cut off the engine, throw the car in neutral and coasst down a 2/4 mile downhill slope to boot!!!!??? OVER 700 miles on a 13.2 capacity tank is literally running the car on fumes past 689 miles. (if he is REALLY getting 53 mpg) The information really does not pass the probablility test on triangulation.

Yup, he proudly proclaimed that he was a hypermiler and would leave no stone unturned in search of that last 0.00000001 mpg. Geez, I'll bet that if you came out with a negative twenty "W" zero (i.e. -20W-0) oil and claimed that it would improve fuel economy at the expense of engine longevity, he'd buy a 55gal barrel in a heartbeat.
