5.4L ENGINE GETTING ABOUT 10 MPG

2006 Ford F-150 • 72,000 miles

Truck has 6" suspension lift, 20" rims, 35" tires, and full flowmaster dual exhaust. Only getting aroung 10mpg. No warning or engine lights on. Just replaced o2 sensor #2 in bank 2. No other codes in computer. I know lift and tires hurt mpg, but that much? Supposed stock rating at 18 mpg. HELP!

This will cause a lower mpg for sure.
