What is it a 4 banger

 

---AutoMerged DoublePost---

Who would anyone buy a diesel 4x4 dually for fuel economy...

The capability/necessity to tow heavy......yes

Fuel economy?...

 

Guess donkey boy got what he wanted a rise out of everyone... I wouldn't have waisted that much time on his thread due to the fact of lack of response on his part, I believe both sides have excellent points but really 25.9???? far fetched!!!!

Vcustoms86_ Love the avatar!!!!!! where can I get me those???? LOL!!!!

 

I've gotten that good but I don't think it could happen on a 6.7 dully. I've got a 3/4 ton and got 26 on my way to/from my sisters in Lubbock. Running right at 70 all the way. I've had a best of 28 but that was with a tail wind.

 

Is this going off the overhead or hand calculated?

 

^^ 2x

26 MPG at 70! that's a little hard to believe

 

i get 22-23 with my 08 2500 6.7 3.73 gears. the over head reads about a mile more than i get. i have seen these overheads crazy as hoot owls but both ways on the neg and over.

 

This is Hand calculated.


You don't have to my wallet and truck prove it every day.

 

I have egr delete xrt pro turbo back it ran great until I put the egr delete on now it whistles @ 1800 rpms I don't know if anything is wrong but before that it was great

 

no i dont

i am not saying its impossible, just pointing out that with the average statistics you would be in the less then 0.001% category with MPGs like that

some will get 22~23 on the highway but most will never get that high. exceeding it is a rare bird indeed and will require more proof then an internet post to be believable

no hard feelings, just pointing out that i am in disbelief about those numbers
