Without fail, my light comes on with 5 gallons still in the 24 gallon tank. Figuring a minimum of 15 mpg, I still have a range of about 75 miles when the light comes on.

Before adding the FWC and 285/75's, I was averaging 18.9 in town and 22.1 on the highway. The highest mpg I ever got was 23.8 I tracked it very consistently for 2 years, right up till Katrina hit and gas went over $3 a gallon.

FTR, with the FWC and 285's, I get 15.8 in town and 17.9 on the highway.
