Anyone noticed less fuel mileage this winter?

Corn ethanol is completely asinine, it takes more energy (most of which comes from "dirty" off-road Diesel non-emissions farm equipment and coal-fired power plants) to produce than it yields, and can do damage to engines/fuel systems not specifically designed for it (virtually all small equipment engines and most older automotive engines). Not to mention its effects on food supplies/prices and the fact that it incentivizes to plow/plant more land doing even more environmental and ecological damage, increased use of chemical fertilizers and pesticides, etc..
Corn ethanol is not sustainable either environmentally or economically (without govt. subsidies and mandates) and has no business being in the US fuel supply.

It depends on the kind of ethanol and what it is being used in. Ethanol from more efficient sources (such as sugarcane, or ag-waste/grass if they ever prefect that process) in engines specifically designed to run it and fuel systems specifically designed to handle it (such as what they have in Brazil) does make sense.

Of course we all lose a little fuel mileage in the winter especially once the snow is on the roads, but for me it has been terrible this year. Both my 85 XJ and my 96 F150 are suffering. I have talked to others at work and they are complaining about it also. My Jeep went from 18-20mpg last summer down to 12-14mpg this winter, with a 2.5L. The F150 normally gets 17-18mpg and now I am getting about 13mpg. This seems to have started around October and I would think it was just something wrong with the vehicle if it wasn't happening to both at the same time. That along with others having the same problems. What I am wondering is if anyone else has noticed a similar problem and if it could be due to the gasoline we are getting now? I have tried both regular and plus grades of gasoline and get the same results. I also notice that the power in both vehicles seems much less than before. None of the stations have the pumps labeled as E15, but who knows maybe that is what I am getting now and that would cause some problems I think.

I won't rant on, because I could go on for days, but the media really gives a bad deal to farmers on subjects like this.

I will agree that corn ethanol is a bad idea as a fuel from every perspective for us here in the US. The one thing that most people mistakenly believe is that it helps farmers get rich. In the end farmers get very little of the subsidies and incentives, most go to the ethanol producers and are eaten up by the middle men in the markets. Currently farmers are getting around $4.50 per bushel of corn, in 1970 they were getting around $2.50 per bushel. Since that time land, fuel, labor and equipment prices have gone up something like 7-10X while what they sell, corn, wheat, cattle, ect has gone up maybe 2X-3X.

All of this is very informative and enlightening!
But to the OP- ill bet 5 bucks that your fuel mileage is actually due to the cold weather reducing the air pressure in your tires. Go outside and check it. I bet its less than 20lbs.
Air them all back up and enjoy your gas mileage on me!

Before all the snow here it had dropped to 14mpg, temps were still in teh 40-50F range. With the snow it drops to about 10mpg but that is because I can't get up to 40mph to get the torque converter to lock up. When the roads are clear though it is now down to 12mpg. Waiting to see if it gets better once summer arrives.
On a side note, would fixing a vacuum leak ever make mileage worse instead of better? I found a small hole in the line going from the PCV into the bottom of the carburetor and replaced that line, but I think it had gotten bad a month after I fixed that.

Well back again, warmer weather and possibly the change to summer blend has begun.
I ran several tanks averaging 12-13mpg, then I got a tank that was just over 14mpg. Thought it might be a fluke but the next was right there with it. Weekend before last I filled up on my way to visit my parents, 120 mile trip from that station to their house and back, all two lane country roads with I think 3 stop signs all the way. When I got back to that same station I averaged 17.4mpg on the round trip. Filled up there again and drove on home and after a week and a half of driving to work through some stoplights in my small town I got 16.2mpg.
Seems maybe there is something to the mileage drop due to different blends. Going to keep an eye on it over the next few weeks and use different stations to see if it averages out with higher mileage on both vehicles. I am hoping for that near 20mpg I got last summer
If it was the different blends that caused the problem, then that means I lost 30% or more of my mpg when using the winter blend versus the summer blend.

Gasoline has 128,000 BTUs, where as E10 has only about 95,000 BTUs. The higher the BTU rating the more energy the fuel has. E10 has less energy so it requires more fuel to do the same amount of work as gasoline. It's also harder to ignite because it has less carbon atoms. The carbon atoms help carry the spark across the spark plug gap because carbon is conductive. So how is ethanol fuel better than gasoline? It's only good for the government, not the consumer.
