Depends on how you drive and how heavy the load is loaded.

Empty I can get 20 really have to be trying and where is the fun in that. 17-18 is a good average for me. I live off a highway rarely any city driving.

13-15 towing average

That's a broad question. DPF days I'd overall average 12-13 mixed driving. Few mostly highway trips were like 15 average and the one time towing 5K single axle concrete pump was 15 average. Post DPF days an even mix has been 16 average and pretty much all highway is 18-19. I loose a ton of fuel on surface streets because that skinny peddle is so fun haha

My '13 LML will get close to 20 highway driving 55-60, 18 interstate 65-70, 15 city/highway combo. Towing around a 4000 pound enclosed trailer getting 13.5 mpg. Extremely happy with those numbers, just turned 3400 miles on my rig.
