OK here it is.

I have been making mods to my 2004.5 CTD since last April and have almost bragged about my milage with the auto and 4.10 gears.

We loaded 5er to the gills last Friday (grossin' 20k) here in central NC and traveled I-40 to Nashville and then I-24 into Kentucky to Union County, ILL. We were in truck for 14 hours yesterday and drove into home this morning. Never checked milage a single time till we walked in the door. Total miles driven was 1697.1 and total diesel used was 138.9 .. That comes to 12.2 mpg. You can look at my sig and see the equipment I have.

There was not a single grade that we ran that we could not run that the converter stayed locked. We averaged speed from 65-75 mph. Never over that. We pushed the CTD HARD... I mean real HARD. We ran the TST on 4/4. My overhead closely stayed on 12.5 to 13.

Hosses of Hosses this CTD IS!
