Well, if you live in a climate work snow/ice of course.

I know mileage drops off in the winter due to winter blend gas and colder weather but I lost about 5 mpg even before it got cold and my car doesn't seem to have as much power as it did. Just wondering if the gas wasn't as good as it used to be.

Probably mixed with ethanol. If I pump fuel with that in it my mileage drops about 50km to a tank and def less power.

Plus if you leave your car running so it's warm, you burn gas going nowhere.

Well that's kinda illogical don't you think!!! My Cobalt burns 1.4 liters an hour idling, so .23 liters every 10 minutes.

Here's my graph for the Cobalt for 2012. In Canadian gallons mind you. It still shows you fuel economy lower in winter than warm summer months.

One of them does, but mostly idling at lights kills any good average.

I haven't change my driving habits and I don't let it warm up so I guess it must just be the winter gas.

Winter gas is only part of it. Cold air means you need more fuel. If you don't let it warm up that means torque converter lock up will not occur until transmission reaches operating temperatures so for the first 10 minutes of your ride lock-up doesn't latch therefore engine RPMs are up 10% burning extra fuel. All the grease in all the bearings becomes hard in cold weather and harder to turn until it warms up.(2CVjoints and 2 Tripod joints) (4 wheel bearings)Driving through snow is also fuel consuming. You probably have heater motor full on and rear defog adding drag on alternator. It all adds up.

My car is a 5 speed and I don't turn the blower on until the coolant temp is 180 and then only to number 2. I think the gas in my area is crap this year because my dad's Aveo also a 5 speed getting lower mileage then last year.

Do you know what the oil in your manual transmission looks like at 0 degrees?
