Or perhaps your driving habits have changed. When you change slowly, you might not even know you are doing it.
Or maybe it is bigfoot in your trunk weighing you down, we can never be totally certain.

Ethanol burns up a lot faster then petrol.
I was looking at buying a Tahoe a couple weeks ago. According to chevy the Tahoe gets 15-20mpg. Unless you use ethanol, then it gets 11-15mpg.
I read that juicy tidbit in one of their books at the dealership. I'll try to find it online.
The salesman tried to make a big deal about the ethanol and how "green" the truck was. I looked at him like he was nuts. How is it better for the environment to pay 20 extra cents per gallon and have to use half again as much fuel as you would without it?
Whatta bunch of stooges...
Anyways, I think this is a more likely scenario but who am I, right?

I hate to sound like a know it all, but i know about these things.

Vehicles do burn more fuel in the winter. It takes a little longer for the engine to get to normal running temp. Fuel injectors are wide open at this time. But it could be alot of different things. Clogged fuel filter or injectors and maybe a tuneup.
