I can usually get about 315-320 miles to a tank in my 2011 5.0 with 3.73s and an aftermarket tune running stock sized 27.25" tires. I use 93 octane daily. I live in Pittsburgh and right now with all of the movies being filmed here and bullshit construction, I get a lot of stop and go stuff, even on the highways.
oh ok mine is the 4.6 liter not sure if there is a big difference in the mileage. and mine is running on the stock tune setting, i drive on the highway mostly to get to where i need to get. i have not changed any of my driving habits and i am just at loss.
maybe try changing gas stations, change your oil, air filter etc.
i am almost due for my oil change ill do that later tomorrow after work ill run to the auto part store and get my oil and filter. i was thinking of that being something to do with it but i just wasn't sure but ill give it a try.
