Is it possible to get good fuel mileage out of the EGR/DEF engines? I am having a hell of a time finding a conventional sleeper with 13-spd from 2000-2004 year model trucks (except the long-noses and I wouldn't consider ever driving one of those. I'm not going to push a WalMart building in front of me everywhere I go. I want something aerodynamically designed.) To get what I'm looking for, I'm afraid I will end up having to go with a lot newer model than I had hoped to find.

I run in trucks from 2013 forward, always pulling close to my gross outbound and normally empty inbound. 6.8 to 7.3 is the best I can do and that's running out to the beach and back. Hit the mountains and hills and it stays 6.4 to 6.7. Freightshaker with the wheel well covers and predictive cruise to help the mpg as much as possible.

Thanks for the response. =)
Anyone else?



PLEASE?

I don't track my MPG with pen and paper, just look at the QC or the dash readout. I'm driving a 2017 IH with a Cummins and a 10spd in it and I think the dash readout is about 7.8 but that's only been 20,000 and all in winter with winter fuel. I'd expect that to go up once the engines broken in and I get summer fuel. I'll try to remember to get some hard numbers tonight but don't hold your breath, I forget some things now n then.

You n me both. lol
That's not too bad an mpg for a EGR/DEF engine. I expected quite a bit less, to be honest.

I didn't give it a thought till now but I'm empty one way and loaded with no more 25,000 the other. I do run in a lot of traffic and go over some of NYS "mountains".

i've learned its more about how you drive the truck then it is what it is. granted a hood will get not as good as an aero truck but.. my buddy has a few trucks and is a contractor for fed ex. the truck he has thats the best on fuel is his 2015 glider t660 (high 7's from what he says) under that is a penskee rental thats low to mid 7's. but he also said if you put a rough driver into the glider the milage will fall to high 6's. its all in the driver too.

Yes, firebird_1252, that's absolutely true. The company I am currently working for got new 2013 Columbias and put new 2003 engines into them. After break-in, I consistently could get better than 8 mpg from them with a 9-spd and 3.55 rear. On days when I was running light, I could top 9. mpg. But... we get a fuel bonus based on mpg, % of time above 1600 rpm, average speed, % of time above 65 mph, and % of idle time, so I paid attention to those areas and kept them at a reasonable or very good level. Since we had APUs, the idle time was nearly non-existent. Each aspect was 20% of your score and all of it was more or less under the driver's control. Can't do anything about wind, weight, terrain, or traffic, but the rest, you can.
