2011 6.7 MILEAGE...WHO'S GETTING WHAT?

2011 6.7 MILEAGE...WHO'S GETTING WHAT?
VERY DISAPPOINTED WITH MILEAGE. YOU WOULD THINK WITH ALL THIS MODERN TECHNOLOGY A 2011 WOULD GET BETTER MILEAGE THAN A 2002 7.3.
WHAT A LET DOWN. ON AVERAGE I AM SEEING BETWEEN 11-15 WITH THE 6.7
WITH THE 7.3 ON AVERAGE I SAW BETWEEN 14-18.
ANY ADVICE?

16.5-18 depending on how much city driving I do.

My F250 with 355 gears was 16.5 - 16.8 hiway and around 15 average mixed driving.

My F450 with 430 gears runs around 13 mixed driving and close to, but never yet, 15 hiway if I nurse it.

This is hand calculated as both the truck's lie-O-meters were off quite a bit. My wife's new 2012 Fusion's lie-O-meter is just as bad?? I read the thread about everyone's lie-O-meters being dead accurate and wonder how I got the only THREE bad ones??? Oh well. Maybe the calculator in my phone is busted???

Every time I fuel up, the lie-O-meters think they used less fuel than the actual amout I have to add to fill the tank. Usually around 1.5 gallons per tank. If you use the numbers shown on the lie-O-meter the mileage agrees but when you use actual gallons pumped, the mileage suffers.

BTW - if you are interested, the Fusion is getting 33 mpg give or take .4 mpg every tank and that is mixed city driving 100% (work car). We are very happy with the Fusion so far!!! It is a SE with 2.5 4cyl auto.

This is hand calculated. My truck thinks it getting 19-21@80mph. It wants to be a Prius LOL

Hand calc. (lie-o-meter in close agreement)
Mine was getting almost 16mpg very consistently for the first 2500 miles. Babying it, twisting it's tail over the mountains or running 75 on cruise. Didn't matter.

My last tank the mileage plummeted to 11mpg. Now the Lie-o-meter is reporting 10mpg.

Truck seems to be running the same, just getting terrible mileage. I gues I have to take it to the stealer and see if they can figure out the problem. Sadly, my stealer won't do loaners so I have to walk the 25 miles home.

Just bought my dad's 2011 F250 KR 4x4 CCSB with 3.55 - I have had it about 2 weeks and 1200 miles.

In town I am seeing right at 15-15.5 and on the hwy I have seen as high as 20.85 (hand calc) - read out said 19.8 when I filled up. My overall avg. over the past 1200 miles is 16.4.

Best I ever got in my 08 6.4 stock was 14.9 hand calc and deleted was 17.1

I am very happy with the mileage from the 6.7

I forgot to add truck is just shy of 17k miles and is stock right now.

11-13. New engine was getting 14 but after they fixed the exhaust leak it's getting 11 everywhere now.

Seems like the 2011 6.7 im driving is doing the same thing??
Please let know what you find out? We may have same dealer. After spending over 50k with them and having a heater fan problem ... They wouldn't give me a loaner.

I'm a short tripper (5 minutes to work). With that daily trip, plus weekend running around (when I seem to get my regens) I'm getting about 14. It went up to about 16.9 last Summer, likely due to better blend.
