12 mpg loaded......I’m not believing it

I find it easy to believe that's what the computer thinks.
I'd love to see the real mpg calculated via gallons added vs. miles driven.

 

computer is lying. very common situation with new cascadias.

 

Bobtail I could see.
1100 mile downhill I could see.

He might have one of them new eco trucks. I don't remember what exactly they're called but I saw 2 england trucks at Nestle one time. Couple months back.

I know someone that started with prime. They're doing the lease deal and claim they're getting 9. I think their truck was a 19 model.

 

He must have a trailer tail

 

1 trip is not enough to even START thinking about what kind of mileage a truck is getting.

 

I've got a 19 (with the company setting for max fuel economy) and I'm averaging 8.3 to 8.6 and I've also had it for just over a year. I do know some drivers who say 9 as well.

But again this is a company truck that can't pull worth crap for most loads. So take it for what it is...

 

You can’t really trust those readouts on the dash. In my 579 if I have a normal day (blow off one or two loads) the readout will be .5 to .75 higher than what it actually is when I fuel up. If I idle for a few hours to sleep the readout will show lower than actual mpg’s when I fill up.

There is a guy I follow on Instagram that pulls a tanker with a Mack and he is around 10 on a consistent basis, actual mpg’s on paper not on his computer.

 

@Cat sdp ... maybe he has a Glider Kit?!?!?

 

Maybe bobtail.
