Home Forums Gear Hunting Trucks and Four-Wheel Drives 5.3 fuel mileage

Have a 2017 Silverado 5.3 4x4 in Work Truck configuration, with low gears and tow package, plus an aftermarket ODB port module that kills the fuel management . 90% of miles are in town. 13.8 mpg, consistently.

Crappy gas mileage but I love the truck, especially with the fuel management override.
