My Duramax 2500hd gets the same mileage as the ecoboost. I average 19 on the highway, 16 around town and 11 towing the boat and that is driving it fairly aggresive. Jeff Wurl

The mileage is not surprising. Well your towing miles are a little low you must have a big boat.

Im unsure how a comparison of a half ton gas truck to a 3/4 ton diesel answers the posters questions.

The diesels are better tow rigs but they basically blow chunks as any type of long range passenger mover in comparison to a loaded half ton.

In terms of unladed comfort with just people as a payload the EB has a ton more room in the back seats (and a flat floor) , vastly nicer interior amenities when loaded up and a far better ride.

I love HD diesels, but yeh, no where near the comfort or smoothness of the half tons, new F-150 rides like a Lexus compared to a GM 2500HD lol.

I was thinking, if you already own the 250, why don't you just get a cheap car to drive around, you can find something that will get a lot better gas mileage.

just a thought.

The EcoBoost recommends 91 or 92oct or higher I believe. Something to look into if fuel price is a concern.

i have one with the 3:73 gears its got 3k miles on it so just getting broken in and im getting 19mpg on the hwy at 70-75mph avg speed and 15-17 on the streets. Tows my lavey no problem, towed my buddy's 28 magic last weekend with no issue much better than my 06 f150 ever dreamed!!! I love it

I have same as above. I am getting 16/17 avg with mixed hwy/city.
On hwy only, I will get 21-23 running around 60. I have a heavy foot, so I am sure there is more mpg to be had. I've only towed a 5500 lb trailer and it had no issues. My previous truck was a F350 diesel and I was getting 9-12 mpg with exact same driving. The ecoboost is a great motor. I like mine alot.

What year and have you dont the DPF delete? I know there are diesels out there that get this kind of MPG but here are my reasons against them.

1. They are older which doesnt bother me but I cant see downgrading to an old diesel with 100k plus on it without a warranty, when my 08 has 22k and the warranty.

2. It has a DPF delete, which to get a good system said and done is 2k, plus your warranty is out the window.

3. Its a newer diesel within the last year and would cost me upwards of 40-50k to pick one up, vs Im getting a loaded XLT for under cost at 32k.

Yeah it is an idea that I am kicking around. But I would want to something that is probably 4-5 grand and has a little more reliability than a 500 buck junker. So say I buy a car for 4 grand plus tax title and first year reg I would be out 4500 bucks. It would take 3-5 years just to make up the cost of buying the car. Plus annual maint and older car breaking down, then it may not be worth it.

Thanks for all the info guys so far. It's not said and done at this point I have 6-8 weeks to discuss and research this option.
