What were you getting for mileage before versus current? I was getting around 17 this summer and now I'm down to 14. But I'm in central Michigan and I contribute a large amount of the decrease to warm up/high idle time and anti-gelling additives in the fuel.

Not a whole lot can be done here. Winter fuel blends are about 20% less efficient so mileage will go down. Any lift will decrease fuel mileage as well.

What size tires are you running?

yup, those tires will cut back on mileage. Are you sure your speedo is correct? Have you compensated for tire size?
