Just wondering what everyone is getting on their fuel mileage? I have a 2016 F250 4x4 short bed and get at best 13 around town and about 16 on the highway. When I say highway I mean a longer trip 1-4 hours driving door to door. Not just driving down the freeway. I have just turned 10K miles. I am not to impressed.
This is my 3rd power stroke, 2000, 2008 & 2016. The fuel mileage has dropped from each truck. The up side was the power has increased from each truck.
I have to admit the fuel mileage towing was pretty decent, 11. These where however long trips 300-400 miles one way, towing 3 horse LQ trailer with horses.
Anyhow, just wondering what is happening our there.
Thanks

 

My 2015 gets pretty much identical mileage as my 1999 7.3L, driven the same way over the same roads with the same loads. If you are using the extra power that this truck has, you will burn more fuel - laws of physics dominate.

On the freeway driven conservatively, about 19. With a large slide in camper loaded, about 14. Around town about 14. How fast are you driving on the freeway?

 

With the factory Continental's I got 18-19 mpg (actual, not lie-o-meter reading) on the highway. Considerably less on city roads but never drove through an entire tank to figure out that mpg.
Recently switched tires to General Grabbers all terrain and highway mpg took about a 10% hit. Not unexpected. Drive @ 70-75mph.

 

Same specs as your truck. 20,000 miles in (since February). I get 14 aroind town and 17 highway. Always mixed driving. Regen affects overall mpg. I have never seen 19 mpg....no clue how others get it that high-I don't hammer it and never exceed 75 on the highway. My 6.0 consistently got 17 under same conditions. Then it pulled a 6.0 700 miles trom home. This is not meant for the OP, but I wonder when posts are made about mpg in these trucks if they are from people that are new to these things. I know I would be unhappy going from a 22 mpg beer can to a tank.

 

I drive the truck pretty easy. I have no need to test the power, I use it when I need it, I know it is there. I typically drive 65-70 on the freeway. I would think that is pretty average.
If I was to only check the mileage as I drove down the freeway I would suspect it would possibly be 19. But to me that is not accurate. I measure from my starting point to the ending point. I have not exceeded 17. I have yet to exceed 300 miles on a tank of fuel. Kind of sucks
My 7.3 was better in the fact I didnt have to baby it and still got better mileage.

 

My 2016 burns about 3/4 of what my 2008 burned.
I'm very happy

 

My 2016 F-250 4x4 CCSB with 3.55 gears and 20" wheels gets me 12mpgs with city driving and 16 to 17mpgs with highway driving.

 

Sounds about the same as my truck, on mileage. Same truck I just have 18" wheels.
My 08 did a bit better, again same truck but had 20" wheels

 

I have a '16 XL CCSB with 6K miles on it. I'm getting an indicated 19.1 MPG from day one, actual is about ~1 MPG less. I drive 19 miles one way to work, there is a little light towing mixed in. I get pretty much the same mileage I was getting from my 'yoda 4 banger, go figure.

 

Maybe so but the toyo was just able to haul itself and you. You XL can probably pull / haul a LOT more, and I bet its more fun to drive too

 

My 16' F-350 CCSW lariat combined dashboard reading average is sitting at 17.5 right now and has around 12K miles. I don't know if you are using any fuel additives or not. With the Ford additive the computer said it was 16.8. I currently am using Power Service Diesel Kleen which put it up to 17.5. Again that is the computer read out. Our trip to yellowstone pulling 32 foot TT it said 12.2 over almost 2K miles.

 

My lifetime average over 4k miles is 14.5mpg. I get 19-20mpg at 60-65mph unloaded.

 

True that, I drove my taco for 16 years. I'm 6'4" and about #275, my work buddies have been asking for a while how long I was gonna wear a Toyota to work. I retired it in March. I haven't done any heavy hauling or towing, but I do have the truck for it. I can't slam the yoda, it did some amazing things (some due to operator ignorance) and never failed me, I hope the SD does as well. Once due to poor planning I put a little over 2,000 pounds of tile and grout in the back of the taco (left both of my trailers home). By the time I figured out how bad I had screwed up I was loaded and 40 miles from home (well after dark). The wife asked what I was gonna do. I said drive it till it drops or till I get home, I'm wanting a new truck any how. We made the trip and I started shopping trucks.

I have a Kubota L3200 and equipment that needs to be moved occasionally on a tandem trailer, I figure the SD will do that in fine fashion.

 

Just turned 52,000 miles. All hand calculated. LieOmeter overstated by about 1/4 of 1% over this total, but some tanks by up to 2% either way. Extremes are when loaded with trailer - hard to be level in station. Best fuel gauge is "gallons consumed"

I ignore what happens on half of tank or quarter of a tank. Wind has just too much impact on mpg. Hill and mountains much less- unless you hot foot it up the hill/mountain, you get back going down hill what you lose going up hill.

52k total miles
Maybe 1,000 were short around town warmup impacted trips. Everything else is driving steady for 3-10 hours.
25k empty
25k bumper pulls out 6-9k loaded
12k high profile 17k 5er.
Over the life 12.1 mpg.
I was at 12.5 mpg at 40k miles before I began the 12k trip with 5er. At that 40k, I was at 50% empty/50% loaded. If I were to run the next 12k empty (I won't), I would get back very close to 12.5 overall average.

Best full tank running empty 17.5; worst 14.0. I plan on 16 unless a high wind.

Best tank hauling bumper pulls 11.4mpg, 5er 11.2 mpg.
Worst bumper pull 8.1, (winter fuel and wind), 5er 8.5 (wind).
I plan on 10.0 when loaded unless a high wind, then 9.0.

Most travel is 62-65 mph loaded; 68 mph empty. I am mostly on East coast; maybe 5% of miles are 5-10 mph faster when out west.
Cetane and water treatment every tank.
Algecide every 6 months.
Idle time about 9.5% of 1,100 total engine hours.

 

I am all over the map with mileage, but within what has been discussed in this thread.

Summer which still isn't really hot, but the fuel is different, is 13 to 17 on mixed driving. Long drives on the highway only from fuel station to fuel station and with a regen 17.5 is my best tank. Have I seen 20 mpg after pulling away from the fuel station, sure, but it doesn't last and I agree with the ignoring short term MPG numbers.

Winter I have gone as low as 10.5 (it was the regen from hell, started in -20F and just wouldn't complete) and I haven't done a long enough highway drive in my current 2015 truck for highway only mileage on winter fuel and temps. I'm usually in the 12 mpg range for a city/highway mix. I hope this year I will stay a little higher since I have a heated garage and before I did not so at least in the morning I will start out with a "warm" motor and transmission. However, I will still be in 4WD most of the time. The equalizing factor is that I am not able to go as fast in the winter as the summer.

All of this is unloaded, stock truck, OEM 20" Michelin M+S Tires, 3.55 elock rear. I don't drive easy (hypermile) or abusive. I drive aggressive if you ask a Subaru driver or normal to easy if you ask another truck driver.

Pulling a 18', but 24' overall 7' high cargo trailer I was at 11 mpg, give or take. It was loaded down decent and I had a lot of city driving with it as well.

Can't really say more HP = less mpg or we would be getting gallons per mile. The first cars got horrible fuel mileage and they had 10hp maybe less... 6.7 is more efficient than a 7.3. Completely different motor technology. My old fox body mustang from the 1990s had 225 hp and got worse mileage than the new 400-500+ hp Mustangs of today for a more recent example. Sometimes if you have more power you are easier on the throttle too.
