3.7L Fuel Economy Hints and Ideas

I'm wondering if a tune would help too. I got that average up to 21, but I'm having to be utterly ridiculous to do it. Getting over 20 in the city in this truck is very hard to do. If a tune would make that easier, I'm all for it. As a side note, your signature mentions ambient lighting... where'd you get that?

80% Superslab at 75 mph, 20% city traffic,
average cargo load is 1,000 lbs, often more, counting a topper, bedslide and me.
I'm at 3800 miles now and just drained the blended oil and replaced it with
Mobil 1 full syn, that netted me a .6 mpg increase.
Computer average is holding around 20.9 mpgs
I'm still on the factory noisy AT tires...
I'm very happy, love my 3.7
FYI my now gone Toyota 2.7 liter auto got me an average of 21.5 under the same
conditions.. It became unreliable at 528K miles...
Not bad being a gutless 4 banger that wouldn't get out of its own way... I always had my foot innit....
So as far as I'm concerned I can forget about mpg's and enjoy this far more
powerful, comfortable and safer truck..
Thanks Ford XD

I have the 3.7L Screw XLT 2WD and at best on the highway I get 15-17 mpg, even with keeping it below 70 and not using the cruise control on hills. Is that low? I see folks reporting much better mileage. My truck came with a grille guard, exhaust, and a leveling kit and I put Michelin LTX MS/2 tires on (it came with 295 70R18 Nitto Trail Grapplers which gave me 12.5 mpg). Any ideas for better mileage?

Synthetic fluids, Lightest ply tires/ smallest size possible, Leveling kit removed, 5* tune, new plugs, air filter, clean MAFS, etc

You Americans are spoiled with your highway system and speed limits. 60mph is average highway speed limit around here, 65 in some other provinces. do 70mph and you will be getting tickets, never mind 80mph.
Consider the average 3.7 is rocking 3.73 gears for more low end power and acceleration, it is not a surprise to see big fuel econ penalties past 70mph.

there is 1 highway in the country with a 120 km/h (75mph) speed limit... they had a news girl drive it the other day and she was all giggly, big grin on her face when she got to 110, 115, 120... "omg I'm doing 120 km/h"... that was funny...
