Shell gas
Just in case anyone is interested, Shell Gasoline is the STUFF.
Awhile back, I was having problems with Spark Knock on my 97 F259 351. I tried EVERYTHING to fix the problem, and didnt even have any codes but still had the clatter. Well I figured I would just have to live with paying for the Super Unleaded to stop the clattering. Well I one day I put in Shell Regular Gas (Nitrogen Enriched) I dont know what that means, But I can run Regular gas from Shell in my truck and no Clatter and a little better milage. Well it goes alittle farther.
I filled my wifes 05 EXPY 5.4 with the same gas she always used and drove to Orange Tx, getting about 13.5 mpgs, thats what it consistently ran. On the way back, we had to fill up again ( Its about a 4 hour trip) anyway, we filled it up with Shell and the gas mpg's increased to 15.7, that was about 2 weeks ago. Usually after a week of in town driving, it drops a little. Well after 2 weeks of in town driving, it is still getting a consistent 15.6 mpg. Now I ONLY use SHELL gas.

I was wondering about Shell Gasoline. I'm glad you brought this up. Shell gasoline is more expensive than what I get from Wal Fart, but I always use Plus at Wal Fart and High Test when I can afford it. There is a noticable difference in my truck when I use higher octane fuels. Maybe I should try Shell's gasoline and see if it's "cheaper" for me to use in the long run.

Run a couple bottles of Gumout thru your gas tank. It may not solve your issue but it will help. My truck idles better now that I use Gumout. Your 300 should be getting better than 11 mpg with the way it's set up. I get around 8 - 10 in the city with 31'' tires and about 16 mpg hwy.

Run some high octane thru your tank with Gumout and see what it does. When was the last time you changed your fuel filter? Have you checked your codes? It sounds to me like your truck is running fine on the highway. More experience men on here will be able to help you out.
