Is this normal?

There are ton of threads about this, but to summarize:
-Winter grade gas will drop your mpg's
-Colder temps drop your mpg's quite a bit, since it takes so long for your drivetrain to get up to operating temps and for the tranny to begin operating efficiently. Tires are stiffer for a bit too when cold (and check your tire pressure).
-If you let your truck warm up longer in cooler temps, that will hurt your mpg's too.
-Shorter trips, less than 15 minutes, hurt your mpg's, especially in colder temps.
Those apply to all engines/trucks, but the EB seems to be affected more than the others. That's probably due to the turbos spooling up sooner to overcome the sluggish drivetrain and tires until warmed up. Once warm, and on longer trips, my mpg's are equal to summertime (5.0 engine). I would bet that goes for the EB too. Also, don't baby it too much. You'll get better mpg's by getting up to speed moderately rather than sluggishly, and by using less brake and coasting up to stops sooner.

For the last 150 miles, mostly city 14.1 mpg cold Wisconsin winter and very seldom let warm up
For the last 9000 miles 15mpg mixed
I have a heavy Platinum Eco with 3:55 axle
I feel that my mileage is fairly normal.
If I'm on a trip with no headwinds and stay around 65mph, I'll get right around 20mpg I'm going to reset my lifetime mileage at 10,000 miles and see what I get. This mpg should be just slightly better because my break in should be complete

Absolutely!!! I saw my mileage also go down on winter grade. I should add that the eco is EXTREMELY sensitive to your driving habits. I'll give an example………
I live about 14 miles from town or 28 miles round trip or there about. The other day I did a test to satisfy myself. Went into town and drove without engaging the turbo's or very very little. I go 21.4 mph driving around 60 mpg. On the way back I drove like I normally drive… yes… using the turbo's and driving briskly. HAHA!! Well I got 14.6 mpg on the way home! Today I duplicated it only this time driving my normal style into town and driving conservative on the way home!! Almost the exact same results or within 4 tenths….
My buddy (conservative driver) drove my truck to NJ about a 180 mile drive the other week… I rode shotgun! He got around 21 mpg… I drove it back and got 15.6 mpg… Now the clear FACT is he got much better mileage because of his driving habits. I know people CLAIM they drive conservative but in reality they are probably constantly tipping into those turbo's.. those turbos FOR SURE suck a lot gas!
Bottom line.. I think good mileage is obtainable on these trucks providing someone is capable of driving a certain style. To be honest I could not care less because I got my Eco for power and towing…. Not going to worry about the mileage because it is……. what it is!!

i drive 60 miles round trip for work everyday in my EB XLT SCrew and most of it is at 55mph on a back highway and a 5 mile stent @ 70mph....i just averaged a whole tank at 19.5mph...this is driving somewhat conservatively but i don't have "winter grade" gas here in louisiana

asking about MPG issues on the internet is like asking "does this milk taste funny to you?" on the internet .... unless it's obviously bad (ie; getting 4 mpg, or "when I try to drink it only chunks fall out of the jug") there's too many variables to get any real feedback.
plus I'm betting most who have issues with mpgs still add hundred$/thousand$ in mod's to their truck - so have fun factoring how much gas those mods could pay for (and how much weight they add, or how much worse your aerodynamics are afterward). just drive it. if you can't afford the gas, sell it.
