When I got mine, I was getting right around 18 with a roughly 50/50 mix city/highway. I have not driven a full tank exclusively on either in the 9000 miles I've had the truck, but I did show close to 23mpg over a 3 day period of mostly highway driving, but by the time I needed to full up, I had put a bunch of city miles and it skewed the numbers.
I put a set of FX 20s with the stock Pirelli's (275/55 I believe), and a K&N intake, and one or both caused my mileage to drop to around 15.5, give or take a few tenths. I know my speedo and odo are off because of the tires, and according to one website the odo is off by about 4.4%, which would be around 16.2mpg if you factor that back in. Still lower than stock, but it's a truck, I dont expect good mileage.
This is a '13 RCSB.
