E-30 gets better than e-10

Just made a 70 mile local round trip this evening... 90% back roads/highway and averaged around 50 mph. Display shows 18.7 mpg (last fill-up was Kroger 87 octane). I manually shift, keep it in 6th gear during all up/down grades, and maintain speeds between 40 and 60mph. Only mods are K&N, bedcover, mid-perch and about 2500 miles now.

Maybe I'm a bad driver...I average 11.5 around town with mid perch and Toyo MT's.

Or maybe I drive 'er like she wants to be driven...

Only city driving ??
Cause that is low for an eco

A mix of 60 city / 40 why.

Went from South Jersey > Rickett's Glenn PA, up / down that 18% grade road several times, and then back home. She avg. 13.7 mpg there and 14.2 mpg back. We had 4 people in the truck, atleast 500 lbs of stuff in the bed, and were not driving slow at all... we made the trip home in 2hrs 31m and the GPS said it should of taken 3hrs 10m.

2013 raptor supercab.
Was averaging 14.1 for lifetime mileage of 28,000, running low octane.

Running high test, for 4 tanks and then resetting the monitor, I am now up to 14.9 after 800 miles. Will update to see if that holds true.

Maybe Im driving like a D-bag but I just flipped to the economy screen and it showed 10.6. I do, however, idle quite a bit being in the construction business I do a lot truck sitting. But I still would have guessed better than that I mean thats pitiful.

Dialing kills mpg even 2 min.

160 miles of highway driving (pseudo off-road, given road conditions in IL) on 93 octane...14.5 mpg. Given that the flow of traffic runs at about 80, not bad.

I have been getting 15.5 in town and 16.5 to 17 on the Interstate for 40K miles. Recently observed a reduction in fuel economy by 1 to 1.5 mpg. No changes in driver, driving habits, driving environment or fuel. Vehicle diagnostics say everything is okay. Air filter is clean. Tire pressure unchanged at 44 psi. I don't get it. Any ideas?
