Here is some SPECIFIC information about warm weather vs. cold weather fuel economy on a Corolla. Not a Yaris or ECHO, but it's another small-engined Toyota so it might be relevant. I'm sure you'll let me know if it's not or if it's not specific enough for you. Or if it's not what you're looking for you could just use the Page Down key, it would be faster and friendlier than picking on someone's post because it's not specific enough for you.

#184 of 598 Give Backy a Break by micweb

Although Backy is (seemingly) incorrigibly dedicated to singing the praises of Hyundais, there are a couple of things to keep in mind before taking pot shots at him:
 
1. He is very well informed, as evidenced by his insightful economy car test drives/comparisons here on Edmunds;
 
2. He's usually, although not always, right.
 
In this case I vote with Backy. Your lower gas mileage is probably due to the onset of winter.
 
The EPA has acknowledged, in coming out with its revised 2008 criteria for gas mileage reports, that one of the major factors decreasing gas mileage is cold weather. This is for several reasons: the engine has to run richer, hence less fuel efficiently, while warming up; the engine has a deeper hole out of which it has to warm up, so warm up takes longer; it's colder outside, so warm up takes longer; a 5W-30 or 5W-20 conventional motor oil is thicker and less fuel efficient at freezing temperatures (a synthetic, especially a 0-30, can help in this regard); using the cabin heater slows down the warm up process; and there is more road friction on a wet/snowy road than on a dry road. Until the car warms up, it needs a richer fuel mixture just to keep running, and friction is higher than at full operating temperature. And the tires are stiffer, and hence less fuel efficient while warming up. Finally, most people take short trips (5 miles or less) which amplifies the "hit" taken from the cold weather.
 
This affects ALL cars, not just Yarii, so Backy was right to chime in; although the difference in mpg, in absolute numbers, appears greater because 15% of 37 mpg is a bigger number than 15% of 14 mpg.
 
Finally, many states switch to "winter blends" of fuels which are also less energy rich and further affect mileage adversely.

I'm not looking for votes, pal. This is the Yaris Forum and I'm looking for qualified input from actual grown up owners like myself. I'm not looking for "probably" or "revised 2008 criteria." If you do not have actual experience to respond with, but are lonesome, please phone a friend.

You have a lot of hostility bottled up there. Did a bully steal your lunch money when you were a little kid?
 
Winter driving and its associated fuel mixture will affect ALL cars, including your Yaris. There is no need to be acting like a spoiled little kid....

In my Echo, which has essentially the identical powertrain to the new Yaris, winter has had virtually ZERO effect on my fuel economy. However, I live in California, where we don't get much of a winter (except for that CRAZY cold snap that lasted about a month). It DOES take longer for the little blue light to go out in the mornings this last month or two, and I have noticed that I have gone from a running average of about 41 mpg to about 39.5 for the last several tanks.
 
Not sure if that helps, or if I'm qualified to answer...

I'm acting like a "spoiled little kid" because I request some qualified input as opposed to irrelevant drivel from people who feel the just have to say something but have nothing of value to say? How would you say you are acting dkarsch by jumping into a thread to attack me when you have nothing to offer either? Maybe I'm not the only one with something "bottled up"?
 
You needn't get too "EXCITED" lucy. Trust me, it will NEVER matter. And what's your excuse? No more spaghetti in the house? You don't own a Yaris either. All you do is make disparaging comments about them. Thanks for dropping by to leave another "DEPOSIT."
 
Nippononly--at least you actually drive one of the cars I requested input about. Thank you for your input. (See, I can be perfectly civil.) As to your crack regarding whether you are "qualified," the weather in NW Ohio (per the post where I proposed the question) has been below freezing since the first of January. You must be pretty smart if you live in California. You figure it out...

When you act like an A$$ and are rude to people who are trying to answer your question, then you shouldn't be surprised when you are called on the carpet.
 
As I stated before, and you should know this if you live in Ohio, winter fuel mixtures and the cold weather will have a negative affect on a vehicles milage. It doesn't matter if the car is a Corolla (which I drive), a Ford, a Nissan, or a Yaris.

Called on the carpet?? I have news for you...I don't work for you, butchey boy. The closest thing to a qualified answer so far was from nipponoly who drives an Echo. When you drive a Yaris or Echo feel free to share a real life experience. In the meantime go check the beagle for fleas and mosey over to the Corolla forum with the rest of the librarians and bean counters. And watch your language, too, there preacher.
