I would suggest that your friend start with the basics - fresh fuel filter, oil change, check & replace the air filter as required, if it has not been done change the axle fluids & tranny fluid, a diesel purge would also be a good idea IMHO - DIY DIESEL INJECTOR SERVICE
The following may also offer some suggestions Smoke Tells A Story

Just to compare gas v diesel, I have a 2013 GMC 2500 HD Crew cab w/ the 6.0L gasser and 3.73's, and I'm getting no better than 10mpg towing a 5800lb Roo, and my empty city/backroad mileage is around 14mpg.

Granted, I have only 700 miles on the thing, and am trying really hard to evolve from my lead foot days, but I thought it might get better than this. Almost regretting not sticking w/ a half ton.

when did GM start putting in 3.73`s in the HD that was the option in the LD and the only gear set you could get in the HD`s was the 4.10. I ordered and that was the only option, unless you got the dmax

first off keep the stock pizza cutter aired to 80psi, slow starts, take foot off pedal a long way back and coast to a stop

I had one also and it was a gas hog...


I currently get 16city 22hwy, towing the 12.7k 5er I see 12.5 all day. I am far from stock, execpt for the tires.... replace the rear diff fluid with mobil 1 syn gear lube 70-90w, and also do the front and tcase, your rear is 1qt low from the factory, so do this ASAP 4qts will fill it, the tcase fill with 5w30 syn motor oil 2qts, and front 2 qts of mobil 1 gear lube 70-90w. this should help on the milage. their are a few other things that will help but it will cost about $1500.00 and in the long run pays for it`s self real fast, like EFI tuning, and a exhaust from the turbo outlet back

Yep...reason I gave up m '09 2500HD gasser, wasn't impressed with the 6.0 motor after pulling a 9500lb TT for a few years.
