Mpg on 6.0

[Dieselroller]

Just wondering what kind of fuel milage everyone is getting? My dash says I'm only getting like 12 mpg. Is that right? With lift 35s and Tony tune.

 

[jdgleason]

All in how you drive it. On 35s I would expect anywhere from 12-16. Dash isnt terribly accurate, I would hand calculate it a couple times and take an average.

 

[PTSUPERD]

Right at 13 mpg here....with a heavy right foot on 35s.

 

[Dieselroller]

Ok, just making sure and. Yea my foot ways a ton! Haha

Hand calculated I'm getting about 16 out of mine, bone stock leveled with 33's

 

[STROKER]

well my dash says im getting 28 right now:fustrate: when we took it down to kansas i hand calulated it and i was getting bout 18 on the highway

 

[Dieselroller]

Yea. I guess it's just the big tires and wheels. I had a cracked y pipe and thought once I got that fixed my mpg's would be better. But it didn't change at all once I got it fixed. Oh well!

 

[constantfix]

14mpg hand calculated :flush:

I thought i would do much better w/ 155's

As long as I'm not towing, I avg 18-21 mpg bone stock. I don't drive her easy but I stay consistent with my speed.

17-20 unloaded and driving about 55mph. Anything above about 60 and the mileage drops like a rock. BTW, these numbers are hand calculated and very consistent over the past year. I get slightly better mileage in the winter.

 

[yeehaw]

i got 21 with mine going to indiana and back a few weeks ago, average was 60 mph

but usually around town here i can do 14-16 by hand calculating

 

[Dieselroller]

How? Is just cause of the big tires and stuff?

 

[yeehaw]

i was getting horrible MPG (like 10-12) before my low pressure fuel pump (the one in the frame) took a crap, after that was fixed it has gotten a lot better

all summer i had the 20s on with stock 265 goodyears

Highway between 16 and 17.5 with my SRL tune...getting between 12 and 14 in town with a decently heavy foot...six speeds are too much fun with 4.10s and a tune LOL

I get 12-16 hand calculated around town with a heavy foot and completely stock truck. The best I've seen was 19 going real easy.

I can get 20 out of the Ex if I really really behave with it. On the interstate running 75'ish I average about 15. In town it drops to around 13.

 

[Socalferret]

In CA I get 17 mpg highway, because of the degraded diesel. But in Washington state, where I fueled up before going back to CA I got 22mph highway. Both ways doing 70 mph. I try to keep the RPMs at 2k. Currently traveling through NJ and getting 19 mpg. 70mph. Jersey drivers suck.

 

[PSM_Kid]

I get 14-16 hand calculated depending on how I drive and how long I let it warm up before leaving to and from work.

 

[4tonGT40]

Hand calculated I'm getting about 16 out of mine, bone stock leveled with 33's

16 Bone stock???? Do you drive down hill everywhere? I have an 08 F250 when mine was bone stock the best i ever got was 11-12 MPG. Whats the secret?

 

[Sprman]

hand calculated i get between 15-16 with 5.5" lift on 36's with a race tune from Matt. I got 12.3 hand calc'd while towing my 11K 5th wheel from Houston to central Alabama. I guess i got a pretty good one compared to some of y'alls.
