Last Sunday mine was 7.12 mpg and 6% out of route.. Then again, I'm new and got stuck in the oldest truck in the fleet.... LOL no apu or inverter... And I can not sleep being hot.. so I imagine my mpg's will be going down even more here soon!

I live about two miles off i-55 in Illinois.... So that definitely helps my out of route percentage.

I was told not to fuel on Fridays and that would boost your MPGs, but it seems like that trick would catch up with you the next week. Out of route is another story, and nobody can explain how any of this really works.
Would be interesting to see how the 2013s do with that new motor DD-13 in them.

OOR about 18%. Getting 500 mile weekend runs with 150 miles OOR doesn't help that one bit. Neither does multiple minimum mileage that start off on the wrong side of a large town like Chicago. Everyone's OOR would go down instantly if Maverick instituted practical miles and PUBLISHED the route the tariff miles were calculated on. The current tariff mile calculation is archaic and outdated. OOR only advertises this so all can see how absurd it is. IMO, OOR is luck of the draw.

Fuel mileage. With the wind, about 8.2 on average. Against the wind, about 6.7. Overall, about 7.1 currently. IMO, fuel mileage is more luck of the draw than anything else.

I worry about neither of those two numbers anymore. Neither do I worry about BS comments from management about how drivers need to average "462 miles per day". As far as I'm concerned, it's managements problem to keep the truck rolling, not mine. I keep the left door shut and drive as slow as the schedule will allow (except Fridays, when I drive to maximize home time).

BTW, I hear the new DD13s are already crippled (entirely heresy). What a shame that one guy at Maverick knows more than the hundreds of engineers who design the engines, transmissions, and drive trains putting in hundreds of thousands of hours devoted to being able to provide a personal tailor made experience for each customer.
