Fella's, what kind of MPG's are you getting out of your 6.0L PSD Ex's? (Real calculated MPG, not Lieometer) and if above the normal, 12 mpg town, and 14-15 mpg highway, what have you done to achieve those results?

Thanks..

 

I get 11-12 around town, 15-17 on the highway at 70 mph. That's 3.73 gears, stock tires, 4x4, stock engine. On the odd occasion I have to travel on state highways I push close to 20 at 55 mph.

 

I have an F250 with the 6.0L and while not an Excursion it does weigh in just shy of 8000lbs empty with a half tank of fuel and me in it.

On summer fuel we normally see 14-14.5 city and and 18-19.5 freeway.
On winter fuel we normally see 13-13.5 city and 18 freeway.

Freeway mileage is about 68mph, just under 2k rpm. My 7.3L Excursion gets very similar results completely stock.

I have cat delete, magnaflow muffler and Innovative Aggressive Tow Tune, everything else is stock.

Hope that helps a bit.

Cheers

 

Our 05 is very close to fastang50's. I just removed the turbo and cleaed it, so I will see if it helps.

 

when my truck was stock, with 3.73s, 4X4, stock (road use very mild tread michelin) tires, on relatively flat roads i would get 16-17mpg hand calculated. swapping to 285/75s dropped me 1-2mpg. my srl+ tune giving me about 400rwhp didnt seem to change my mileage any. except when i put my foot down goodbye anyone near me as well as fuel economy.

currently with my pretty aggressive 33s, my tune (and a slightly heavy foot) i get 15 mpg almost every single tank. if its all city i average 14 and can see 18 with almost full highway use. i have once, saw 24, but that was on a 1200km road trip all highway already warm engine, and a 2,000 foot elevation drop.

 

check fuelly.com there are a lot of cars/truck mpg there

 

16 pretty standard...60highway/40%city for moi.

 

right now on winter fuel i'm getting 14-15 city and 17 hwy

summer...roughly 15-16 city and 18-20 hwy

of course...that all depends on the pressure on the skinny pedal

 

Your mpg is what the op should be getting, I use cetane booster all the time
Yes the petal to the metal tends to lower the mpg...
But raises the excitement level!

 

Mixed around town driving 15-17, depending on if warmed up or not and how long a trip lasts. I am 2wd, and aren't in a race on the hiway...

Long hiway drives it skyrockets..

When i first got my ex three years ago i got 21 mpg driving fl to nc and return, hiway driving mostly 74-75 (on speedo) which is really 71-72 cruise most the way. Got 940 miles on 45.5 gal on one tank.
Cruising at 2050 rpms or so.

Had the bulletproof setup installed and mpg dropped 19-20, now cruising at 2250 rpms though, in hindsight, i believe forgot to tighten exhaust bolts...

Got ficm repaired w/atlas40 from ed, more response at tip in, not much change in mpg or rpms on highway, but found big exhaust leak at exhaust manifold to y-pipe.

Fixed leak couple weeks ago, drove 250 miles yesterday hiway same 74-75 on dash, noticed rpms back to 2050 and overhead showing 24.8 vs previous best of 21-22. The sg2 instantaneous mpg was vastly better than last months trip, so i am stoked.

I can hand calc once i return and fillup, but ficm tune and fixing exhaust leak sure has paid off to me.

My lieometer is generally within 1 mpg around town, and closer on my longer trips..

13.2 average for the year. (Re: mileage log I keep for self employment)
With current mods in signature.
Knowing what I know now about the 6.0 I can't wait to see the change with the updates i'll be doing shortly.

 

Hey, thanks guys. Mine is exactly where everyone who responded's mpg's are. Thanks again

 

15 in town, 18-19 hwy no matter what fuel I use

Depends...

Mine stock delivers 13-14 around town. Coming back from Amarillo when I bought it, it got 18.3 mpg cruising at 65-70. Modded, highest was 17.5 coming back from tech day in Yoakum.

It a depends on your strategy. My truck was unfortunate enough to be reflashed under warranty and was neutered.

I plan on giving the truck it's ***** back by having PHP roll back the strategy to a more desirable one and tune the FICM for Atlas 40. I'll have better throttle response and better power/fuel economy. Just waiting to hear back from PHP next week.
