On my 07 V-8 4x4 I get 15-16 mpg mixed city and country roads and as high as 21 on the highway. It seems to be most efficient at around 60 mph. Anything higher or lower and the fuel mileage drops. That said, for most of my longer trips where I average about 70 mph it gets 18-19 mpg. I have exhaust and intake mods as well as 265/65/R18 tires and the 87 octane performance tune from an Xcal2. Those numbers came from the dash readout. I have never bothered to check it manually. It's not a Prius. :blink:
