6.7L Cummins Forum

Well I just went over 9,000 miles and I guess 15.5 MPG is about as good as she's going to get not that I'm complaining. As a matter of fact the big pigs MPG rivals both the Nissan Titan and Toyota Tundra 1/2 ton trucks with the low geared rear differentials and I have a heavy duty front solid axle rather then IFS and the engine that will move the world if I could get the necessary traction so I'm content.

I wonder if the Edge juice with Attitude I'll be ordering here on the 21st will help the MPG like they are advertising?

Squid I was wondering if the upgrade you did really improved your fuel mileage?
I am buying my new Dodge soon and had wondered about upgrades.
Thanks

I'll let you know what I find out. I'll also be upgrading the intake and exhaust this year so stand by for more info.

13.8 over 9,000 miles has been my hand calculation. High of 19.3 (HC) over 500 miles, Low of 9.7 (HC) over 250 miles. Been right about 15.5 on the recient average.

I put 6200 miles on my 6.7l since October. It is by far the best driving truck I have ever own. I also have a 2006 5.3l Z-71, and my Dodge is so much more fun to drive than my "Z".

It may be too early to tell, but I read somewhere out on the net that the mpg's will get better around 80-85K on the clock. I am at 19 hwy / 13 city and do not have a heavy foot.

Squid did you ever get the Edge Juice with Attitude upgrade installed?

122k miles on the clock and fuel mileage has NOT changed much since new. Average around 15.5, hand calced, @ 75 m.p.h. empty, 8 -10 towing @ same speed depending on what's hooked behind me and the wind speed/direction ahead of me.
I did read about using the smaller/lighter 5.9L air filter instead of the big/heavier 6.7L air filter to increase m.p.g.'s. I'm experimenting with that now. Initial results are indicating a small, almost 1 m.p.g. increase. Will keep ya all posted with those results as I make some more trips. I'm trying to eliminate all the variables to make sure I'm actually seeing an increase due to the different air filter.
