His sig say's 3.55's.

 

Yeah, Rob's right.....3.55.

Tom I was basically posting that to back up your assertion that the 6.7 is efficient. I think sometimes folks get the 6.4 and the 6.7 confused. The 6.4 wasn't as efficient as this is.

 

Thanks Rob, I was typing from my phone, and the mobile version of the site doesn't show signatures. It's mainly the guys with the 3.31s that are reporting consistent 20+ MPGs with their 6.7s which made me regret my 3.55s!

 

No problem bud!That is one thing I don't like about the moblie version,No sig's.

 

I think your right, people get the 6.4 and the New 6.7 mixed up when talking reliability, mileage and power. Most people I have met with a 6.4 don't like the fuel mileage too much and would rather have the 6.0 mileage and simplicity over the 6.4. That said the 6.7 I hear is one hell of an engine that gets the mileage of a 6.0 and is reliable for the most part. What they hate is the urea fluid and the whole system. They would love the 6.7 with the emissions standards of the 6.0 lol.

 

I have the stock tires on my 04 235/75r16 I get 10 around town and 12 on the highway if I am lucky. I dont know but it seem kinda of ridiculous for it to be that low. I live in southern alabama right now. Its 10% ethanol.

 

i have not seen double digit MPGs since early fall with my DD V10 excursion. 6.5-9.5 all winter long. mostly 8ish. gotta pay to play.


that said i've been driving a '99 ranger 4.0/auto 4x4 i bought around alittle and seeing 15-17mpg mixed.

 

Filled up yesterday... 11.4MPG! Is it sad that that is exciting??

 

Is a paid off vehicle with poor mpgs "saving" more money than better mpgs and a monthly payment?

There are people on this forum who routinely have brand new trucks every 2-3 years, which means they have more disposable income or like debt, most likely the former. So a fully loaded trucks cost isn't a problem for them and there really is no need for justification for anything. They can just afford it.

The there is the lot of us buying used. Some are willing to drop a truck they've taken care of for an unknown high mileage unit based soley on the motor. This is very area dependent but in the rust belt a high mileage vehicle only spells on thing. ROT. So this mileage saving truck turns out to have other problems that eat away at any potential "savings".


Then there are those who put on mileage in one year that most do in 4-5 years. This usage can definitely "justify" one thing or another.

So depending on what group you belong to (or another I didn't think of) its hard to say one thing is better than the other.

I currently have a V10 truck that averages 8-10 mpg an I've chosen to resolve the fuel issue with a cheap car. The truck pulls like a champ when I needed it to and the car saves me fuel mileage and keeps the ROT at bay by using it on the salty roads. I refuse to buy high mileage used trucks so it limits my choices, but that's my choice. I don't want be nickel and dimed by an older truck. So when it came to buy my current rig the diesel version was $10k higher and/or 2-3 years older. I was really looking at diesels but couldnt justify the near 100,000 mile diesel trucks vs the 24k mile, 1-3 year newer gas truck. But that's my choice.
