yeah id say winter gas mine went from 9.5 to 8.2 mpg this winter

 

Where you live also has a lot to do with it. In my old 03 hemi I might have gotten 9 in city. And my now mega barely gets 8 in the city. Here in the la/orange county area of southern California there's a stop light every 100 feet it seems like and I get just about all of them. So all that stop go and sit adds up to chit mileage.

 

I have got as good as 16.4 on the hwy at 65mph. I get around 11 in the city. My city driving is half 55mph to work. Of the 10 mi trip I only have 5 in the 25mph zone. When I plow snow I get around 3 to 4 mpg. hahahaha! wonder why that is.....The numbers are always different for everyone. I use the odometer trip and gallons then check with the trip computer.
