14-16 mpg 2004 6.0

Allright so im getting about 14-16 avg mpg i drive it to work and back at 80 to 90 its a STD cab longbed stock tires and straight pipe is the only thing done to it. I put power service cetane boost in it with every tank and fill up only at truck stops due to the amount of feul that goes in and out of them. About 2 weeks ago i reset the computer to see if i could get any better mileage out of it but all that happened is that it seems to idle lower and lost a dramatic amount of power especially at 80.
Thanks Jbb

Can't comment on the loss of power but the MPGs it is what it is. Buy a beater to commute in if you can.

Yea, I just got 16 mpg going 80-85 back from NC. These trucks seem to drink over 65. Your top end will NEVER be as quick as your low end. Drive a 6.4, totaly different top end.

I have a few questions. What is your gear and what is your tire size? The Kiss of Death on a 6.0 is 75 mph if you are running 3.73. It will take a Intake system and min of 4 inch exhaust to help mpg.

Dan Seitler (dseitler on here) passed away yesterday 04/25/17 after health complications. As some of you guys knew he was a big help in the 6.7 portion of this site and wasn't afraid to be the first to try things. But the past 1.5 years his presence on this site has been low. That was when he was diagnosed with cancer that had reached his stomach,intestines, and esophagus. Most didnt know this because he kept it a private and only let close friends in on his fight against this nasty disease. He underwent radical chemo treatment to reduce it as much as possible. At the beginning of 2016 he had surgery to remove the lower part of his esophagus, stomach, and a portion of his intestines to remove all of the cancer. It was a struggle for him to adapt but he was overcoming the issues and started getting back to normal life. Then at the beginning of 2017 he had a 1 year check up after the surgery which came the next wave of struggles for dan. In his checkup they found fluid in his lungs along with cancer cells. He had to have chemo treatments again but less intense this time, he was past the half way point with it when he began having more complications. He went into the hospital Tuesday 4/25 and started suffering organ failure from his long fight with cancer which sadly lead to his passing later in the day. I was fortunate enough to help him through this fight with his family from beginning to end and call him my best friend. Anyone who knew him knows that he was willing to help anyone and give any knowledge or advice he had with a smile on his face. I know dan had a bunch of friends on this site and people who he did business and had a great relationship with. If anyone wants to reach out to his family or help out in any way can pm me on here or text me a 561-644-5270. Rest In Peace buddy hope you're doing burnouts up there. RIP Dan Seitler

The 108 MM (4.25) works best. We take and cut the Cat so the 108 MM pipe slides through the cat and then re-weld. We also recommend the Volant air intake because it is 100% cold air. Also cutting the header panel and installing a screen ahead of the intake. Both of these will help with mpg. You have the best stock gear for mpg. Pen to paper and not a dash computer is best for calculating mpg. It never lies. I'm sorry but all this cost money but should help. If you are like me 75 MPH will never happened.
