MPG FUEL MILEAGE 6.0 Diesel

[bushpilot]

can't we take a joke sometimes,and stop being so serious.

of course you get better mileage on the interstate with it set on cruise at 70!

perhaps you didnt read his post...he SAID interstate cruising...65-70mph
on a recent 3000mi trip

Can some one tell me if this is normal.... 2004 Superduty F-250 diesel 65000 miles. Just did a 3000 mile round trip. All I can get is 15.5 mpg on paper "Manually".. is this all I should be getting??? 3:73 Gears, 2.5" Lift, Edge tuner/ attitude set on #1, Cold air intake, 5"banks turbo back. Running at 65-70 MPH. 275/65/18 Tires @60psi.Oh Yeah Hard toneau on back. Do I have a problem?? What can I do to make it better?? Thanks For any help New to the diesel world.. Crew cab Harley Davidson 4X4..
