With a a handful of states in the U.S. and nearly all of Canada having temperatures below freezing right now, it may be a good time to highlight a little known secret: cold weather can rob you of fuel economy.

As if driving didn't already cost enough, some of us get to see the cost of driving go up every mile in cold weather. Whether it be snowy roads, freezing temperatures, warming up the car, or just about anything else- it's making your fuel economy tank! (READ MORE!)

First, every vehicle has an optimal operating temperature- the colder it is, the longer your vehicle takes to reach that point (think cold, thick fluids). In the mean time, your vehicle releases small amounts of unburned gasoline and operates much more...

I wish I still had room in the garage for my car. Sadly there just isn't the space.

Because it takes longer to warm up it becomes even more important to combine trips, use the car while it's still hot instead of running it up from cold several times a week, it helps a lot, especially with bigger engines

It's 29 here right now, heading for 23! This is Florida! It isn't supposed to be freezing over here. Where's that global warming??? Al Gore, can you hear me now? He's probably nice and cosy in that mansion of his, running up gigantic utility bills.

So I wonder when "they" are going to tax us even more in the winter because of all the "extra" junk our cars emit during the winter months. I mean Cap-n-Tax after all!

His logic doesn't work down South...I get better MPG in the winter than I do in the summer due to air conditioning. Our winters aren't like those up North so we don't take as long to warm our vehicles up and don't have all that snow to drive through!

It's a good idea to check tire pressure year around but you should resist pressurizing over the mfrs recommended pressure in severe cold. Your tires will warm up from friction and flexion while you drive and increase the pressure. Carrying a pressure gauge in the car and checking before and after driving will give you a fair reading, depending on the starting temperature, for the distance you're going and you can adjust accordingly. The mfr specs don't mention it but there is usually some leeway of a few pounds your tires can be overinflated to allow for this temperature fluctuation.

Cars generally perform worse in the winter therefore fuel economy suffers.

I guess that means warmer weather means better fuel economy. I wonder what a lot of bureaucratic "hot air" would deliver?

However, colder air also means more air into the cylinders, generating higher pressures and providing more power. So, there is some compensation

I do not know how far north you have to go to get your figures to make the statement that "cold weather can rob you of fuel economy." I have lived as far north as Maine and my gas milage always was better in winter than summer.

It also goes down because of fuel blends. I noticed a decrease before the temperatures really started dropping. It's only gotten worse with cold temps and crappy road conditions.
