Gents,

Is this normal for city driving? It's no where near the 17/23 Ford says. The truck is still new, only 1200 miles. I drive slow, usually under 65 and mostly under 2000 rpms. My only mod is the all terrain tires I put on shortly after I purchased it. They are only a little heavier and 1" bigger than stock.

Not to happy with mpg right now

I'm getting 13.8mpg with mostly city on a bone stock 5.0 screw so with heavier tires it's possible

65 in city driving?? that's more like hwy / freeway speed, no?

I'm more like 65 ft / h in city driving here

2013 EB, all-city is around 18L / 100km or 13mpg. It does get better if I hit the main roads with little traffic, but not much...

1,200 miles is still new and not totally broken in so you should see a small increase as your miles increase, but the new tires will probably give you a loss of 1 to 2 mpg because of being heavier and a little more aggressive in the tread.

It takes a lot of fuel to get these things moving from a dead stop, so if you have more traffic lights, stop signs, idle time and traffic in your city driving it will be lower. Where I live it seems that you hit a traffic light or stop sign at every intersection so mine is a little on the low side also.

Two things I see:

1. 1200 miles - let it break in! You probably won't start seeing a mileage increase until about 6k miles, so don't sweat it just yet.
2. City - trucks hate city driving. Stop and go requires a lot of energy to move a big vehicle like that. Combine that with it being new and 13mpg is totally acceptable to me.
3. Bigger tires - regardless of the fact that they're only slightly bigger than stock, there's a lot more rolling resistance from those tires since the deeper tread means more air passing through the tread blocks, which creates more friction. Also, since they're larger than stock your computer might not be reading speed and MPG accurately.

I'd suggest giving it a little more time and breaking the engine in.

Your probably getting better than that. City driving, stop and go, sitting in line at drive-thrus ect throws off the electronic mpg counter. You won't get an accurate read.

stop & go and idling is part of city driving...
if you dont count that, or the getting-up-to-speed part, then yeah, we are all getting 50mpg in the city

I agree with everyone on this, Its new, my 2010 took to about 8k till everything got broken in, some truck's take longer than other's. A little bit bigger tire's with rough tread make a difference also. If you want mpg you can buy a sct tuner with economy tune an adjust for the bigger tire's. Made 2 or 3 mpg for mine.

Ha ha your right. I live close to i35 so on and off a lot.
