Just decided I would share my findings and see what everyone else experiences with winter as far as their gas mileage. I have seen about a 2 mpg drop since it became winter. I figure this is due to the colder weather/engine not warming up as fast, and the crappy winter blend gas they are probably giving us now. Also, it seems as if I get about 1.5mpg better when I use 85 octane 100% pure gasoline, as opposed to 88 octane with 10% ethanol added. FWIW I guess...

Edit: I am in no way shape or form complaining about anything. I will take low to mid 20s any day compared to the 12mpg my old rig got ALL THE TIME. Just wanted to clear that up... carry on.

My mileage hasn't seemed to go down.

Pretty normal findings, fuel economy drops in winter. I find I lose anywhere from 50 to 75kms per tank in the winter.
