I have an 06 LJ Rubicon I bought about 16 months ago. I have been getting very low gas milage compared to past jeeps I have had. I bought it stock and it got about 13-14 mpg and since put 33's on it and is getting about 12 mpg. I know jeeps are terrible on gas but that has seemed low to me. Recently I filled up and 3 tanks in a row for the first time I got about 17 mpg without changing anything else and driving the same. Now it is all of a sudden back to 12 MPG.
Anybody have any ideas why it would fluctuate so much or is so bad to begin with. I am thinking cracked exhaust header or bad o2 sensors.

are you getting gas at the same station? i noticed that when i get gas at the casino i notice about a 1/2 to 1 mile loss per gallon compared to when i get gas at the chevron station. thats just what ive noticed
probably winter gas... they add more ethanol to keep the lines from freezing up, thus the reduction in mileage every october...
