6.0 L PSD Fuel milage

[Metallitruck]

Thought I'd try and get some data on fuel economy for the 6 L, An article in Motortrend had it at 16.6 mpg. Please be accurate and report configuration changes that would affect mileage only (tires, chips, intake etc)

I run an intake, exhaust, and 285/75/R16's. I think I should get better than mid 13's...

Yeah, I picked 15-16, It really all just depends, I can see 18.5 on the lie-o-meter on the highway, and see 12s and 13s in stop and go around town. But, all in all, its prolly around 15...Oh, did I mention mine has a big ole butt...Its a dually

I run a 4" exhaust 285/75/18 on the average i get 16.5 mpg it is 2006 with 15K on it.I have got 19 mpg out of it on a long trips to Colorado.Thats not using the meter in the dash.Filling it plumb full and putting 500 miles on it and filling full again and checking it that way.

I went with 15 - 16 also because that IS what I get around town... About 15 in the summer with the A/C blowing and about 15.5 in the winter.... Don't know the highway mileage because the only longer trips I take are pulling the 5th wheel (at about 18,000 - 19,000 lbs gross combined)... When towing the worst I've gotten is 12.9 and that had it's share of uphill at 60 and 65 mph so I'm not complaining....

Ken....

It very a little when i pulling the goose neck with 10k to 14k on it.I get about 12.5 pulling.

[Rescuediver]

I get around 15 w/ the intake, 4" exhaust, and the Juice on the HOT setting. I seem to get a little less when I romp on it more than not, but I can understand why...LOL!!

[bigd4x4]

your going to have to add some more numbers for me to vote. I only get 8-10

[slammedSI]

Wow i guess i have a freek of a truck. The avg. i get is about 18 at its lowest but i have seen 20-21 before, thats hand added, i dont have the meter. stock sized tires, sct on tow mode, strait piped.
