Do a ECM download give. 10 % plus/minus on what it reads .... Don't go by what someone driving 55mph says unless your drivers care the same as a owner op ... Download will also show emission faults as well if it shows a lot of faults move on to next truck

 

what do you haul, van, flat, tanker??

 

my friend's 2015 prostar with isx450, 10 sp ultrashift, and gets 9 mpg driving 70.

 

Well some are going to get their panties all wadded up but most fuel numbers you hear from drivers are false. Most read the in dash Lie-o-Meter or the qualcom crap of which inflate the mpg in order for the manufacture to advertise their product. Some drivers add a MPG or two to impress others of there supertrucker status.

I am in a fleet of about 30 newer trucks. All 2012 up to brand new 2014. Mostly KW and Petes with the new 680's as my favorites. Some Cascadias. Some detroits, but mostly cummings and paccar. Fleet spec rears (–3.50) and everything from 9 - 18 speeds.

Every day with some 60+ drivers slip seating all pulling the same load around 100K we all get the roughly the same 5.5mpg. That is the same as we got last year too. The few prostars and the maxforces we had last year got no different.

I do look at all the fuel numbers, all the miles, and all the fill ups. We keep track of everything. It is by far more consistant then I expected and no where near the crap I hear from the supertruckers with their BS 8,9, and 10mpg.

 

2004 Freightliner columbia.
1.18 million miles- all original.
13 speed-2.93 rear end ratio.
22.5 low pro tires.
Average speed 72 mph
Loads always over 73k gross
Traveling distance- 2773 miles ( dedicated run )

AVG MPG- 6.09

 

I just bought a 2015 Volvo 780XE with the D13 2.64 rear end. I drive 60mph average heavy weight is 72k. I have a TRIpac so I don't idle. The engine only has 22k miles. First full month MPG was 7.07 and second full month was 7.12. I calculate in a spread sheet not the truck.

 

2013 Cascadia, DD15, 10 speed, 3.42 rears, No APU. 2 quarter IFTA was 7.98, I'd guess about 20k average load in n dry van.
