Fuel Mileage

[groundhog43]

I am new to the group. I am currently in the market for a 250/350 CC 4x4 with a Manual Trans. I have been told that the 6.0 provides much better fuel mileage than the 6.4 or 6.7. I was told specifically that the 2006 6.0 was the best fuel mileage of all the powerstroke engines. Is the 2007 6.0 the same as the previous 6.0 years or was it burdened with more emission control and lower fuel mileage?

Someone gave you a bit of misinformation. The 6.7s get better fuel mileage than a 6.0 could ever dream of. However the price tag for a 6.7 is pretty high right now. My truck gets about 12.5 MPG in town and while towing a 21ft wakeboard boat on the interstate at 70mph. I'm not sure what it gets unloaded on the hwy yet.

My average fuel consumption was 12.5 but I just put a bigger turbo and bigger injectors with a tuned FICM in so I don't know what that did to the mileage yet.

My average is 16mpg completly stock 06,auto,CC,SB,SNUG Top Topper delta box in the bed.

06s and 07s are basically the same,but the FICM/PCM strategies started out differently, but ford dealers usually updated them ,05s used a different intake because they did not have the same MAF sensor, 04s and 03s are very different, 6.4s with dpf deletes seem to do the best for mpg claims(I have not owned one, I love my 6.0s)

I average about 13.5-14 mixed driving, but I have bigger turbo and injectors and a heavy right foot

Just talked to guy I work with, He claims his bone stock 06 gets 20mpg mostly highway...

I have yet to meet a guy with a 4x4 6.0 that has his speedo properly calibrated with hand calculations that can get 20 mpg. Especially on a bone stock truck. Not saying it isnt possible but that I have yet to meet someone that actually does.

Usually the speedos on our trucks (stock) are off by 1 or 2 mph and therefore dont record actual travel distance accurately. Meaning they display more miles than actually traveled and that coupled with the computer saying the truck is getting 21 mpg on a hwy trip basically invalidates any electronic mileage computations.

I guess whatever helps them sleep at night.

ya with my injectors the overhead reads 21mpg and 500+ till empty on a full tank... needless to say i wasnt shocked when i got 300 lol. Also with my wheels and tires the speedo is off by around 8ish (been milking that excuse for being pulled over for a while but gotten two tickets lately that didnt fall for that excuse) however the point of that was to prove that following GPS its more like 1.1 miles for ever 1 mile on the trip odo. Broken down by hand roughly 13-16.

and probably like this guy as well... however i am interested in the miles with the FICM tuned as that is next on my list and possible strategy roll back to something more mileage friendly and no inductive heating

I've got an 06 f250 long bed supercab. Lifted 4" and running 35" tires I get 18-19 on the highway unloaded. Overall average highway and city varies depending on what % of each, but I have yet to see below 16mpg combined. This is with extreme street tune and a light (ish) foot on the pedal.

Agreed! I was shocked when he said that I figured his claim is probably not accurate, but no point in arguing lol
