Stock 2006 V8 Limited on factory 18 inch rims. Blizzaks in the winter. Kumhos the rest of the year.

16 mpg city/highway mix but mostly gentle highway cruise. Calculated on the trip computer and actual calculation of fuel used and distance traveled.

Occasionally 17 - 18 mpg if I don't drive too much stop/go.

Using the smaller US liters (3.78) to one gallon conversion. The Limited V8 is awd all the the time. About $75 USD to fill up every 2.5 weeks. Not bad for the vehicle that is this capable.

Anything else you want to add: I feel like I am getting worse mpg than others. I am slowly going through the truck and changing everything out. Fluids are being done next. So far the brake fluid and power steering fluid were black from the PO.

My ultra gauge says the average is 14.6mpg, but I forgot to reset it before I went on a trip this weekend. LCD screen says around 15.7.
