Over the last month I have been making trips from N. Charlotte NC to my house in Kitty Hawk to take care of Isabell damage. The route I have been taking is I85 to I40 to NC64. It's over 300 miles and mostly highway.
The trip over was on thursday night and I got really lucky and only hit 2 red lights, so the truck only stopped forward progress 2 times

, anyhow when we pulled in the driveway the overhead said 31.1 (I have an EZ and have checked the mileage several times and it's ALWAYS off between 4-5 mpg) So I got between 26.1 and 27.1 for the trip over!!!

I did keep it at the speed limit for the most part 65-70 mph on I85 and I40 and then 60mph on NC64
Then during our stay on the OBX through sunday afternoon I made several short trips to Home Depot, to haul away storm debris, get food, etc. leaving the truck idle while unloading.
Sunday we headed back to Charlotte, I stopped in Greensboro to fill the tank at 720 miles and it took 31 gallons topped off

Overhead said 28.1 at that point and at 720 miles the low fuel light wasn't even on yet. I was on more of a time schedule on the way home and went a wee faster
For anyone curious I have an '03 HO 6 spd QC LB 4x4 3.73 EZ on level 6. I was running Shell fuel with PS diesel kleen and had just changed the fuel filter and the truck had 41,100 miles on departure. Also 3 people in the cab, a Golden Retriever 2 coolers and a few bags in the bed.
Sorry for the long post, I was just really suprised. Previous best was 24.1 over 200+ miles.
Thanks for reading
later
