I have had a new truck for the past two season changes. My gas mileage always seems to change atleast 40 miles to the bad every year when it gets colder. Thanks in advance!

Two/maybe three reasons
- You are probably driving in lower gear more often, due to ice/snow. That definitely burns up the fuel over time.
- The engine takes longer to come up to operating temp. That also burns up some fuel.
- If you change to mud-snows every year, they also reduce your gas mileage.
(- It's also possible that you are driving shorter distances (i.e, just around town) than maybe you otherwise do when the weather's nicer.)
Also, if you have truck made after 1984 or so, you don't (or shouldn't) have a carb. Should be fuel-injected-although the answer concerning carburation is accurate.

I think one factor is that in the winter the ethanol blend causes bad gas milege. Also the cold weather plays havoc on tire pressures. Colder engines usually require more fuel to get to operating temperature. Likewise transmissions. For me: I tend to make shorter trips and I idle more to keep the truck warm..

All engines want to be at a certain temperature. This takes fuel. Most people warm up the cars longer in the winter, this takes fuel. Driving through snow or if your tires spin, you are not getting the mileage you normally get. When traffic slows down and you sit, it takes fuel.

Simple:
Your using more gas
Remember a carburator mixes the air and the fuel mixture to a specific density. When its cold, the air needs more fuel for the same mixture. As the temps increase, less gas is needed.

Most companies use a "winter" blend that has an anti gelling agent it in. Thus reducing fuel economy. I know that they treat diesel this way, and i am pretty sure about the gas.

Well in the cold the motor has to warm up so it has to use more gas. but to have it change 40. there must be something wrong. I'd go ask the dealership.

more warm-up time, maybe you know idle time......OR the force of the snowflakes hitting your windshield is causing the engine to work harder to over come the "force of the flakes" you are using more gas...try driving in the same direction that the flakes are going this should bring your mileage back up...
