M P G Around town V6 DBLC LB

This is also what I get in my AC when I have stretches of 100% city driving. Stop go never over 40 mph city driving sucks for mileage in this truck (not really a surprise though)

EDIT: I'm totally stock minus an OME lift (still on stock tires for now) and a camper shell

 

I get 17 combined, usually about 300 miles per tank. 12 seems low but like others said, it depends on a lot of things.

 

I get between 14-17 city, 18-22 highway, dclb w/ bestop, 12 does seem a little low

 

I get 17-18 city in '14 4x4 off road. Last road trip I got 22 driving up to the mountains. I also have 265/75 Cooper ATP's on my truck, they are p rated and light though.

 

I get around 16 on average with a tank of gas. I have Cooper AT3 265/75R16 tires and it's about to change with heavy skid plates. 12 seems really low!

 

very low, my 09 v6 gets at the lowest 15 and i'll get 19 on hwy

 

I average 15 mpg us (per Ultra Gauge) driving around town but that doesn't include stop and go backed up traffic. Traffic is never bad where I live so its just traffic light to traffic light kinda thing. I have 44 pound 10 ply cooper A/Tw's. DCLB.

On nothing but hwy I can get just a hair over 20.

 

12 seems awfully low to me. I have never seen it on my truck. I commute through Seattle everyday in traffic, still get about 17 mpg on average and go about 310 miles on full tank.

But I have NO lift and run Michelin MS2 tires.

 

I only have 1300 miles on my V6 DCLB auto, so take the following with a grain of salt.

I have checked mileage with every fill-up, and it has ranged from a low of 13-14 (mostly in town) to a high of 20 (one 250-300 mile round trip with about 1/3 highway, but half was in a heavy snowstorm, average speed of 40 mph, occasionally in 4wd due to road conditions).

Overall, I am getting 15-16 with a mix of city, secondary 50 mph roads, and interstate.

One caveat: I bought the truck in Jan, and Feb was the coldest month on record where I live (average daily temp of a little over 6 deg F, many morning commutes at -10F to -20F). Where I live, winter fuel blend and cold temps make about a 10% mpg difference compared to summer based on other trucks I have owned.

Your best mileage will always be on secondary roads at speeds of 45-50 mph if you can keep it there.

 

Twelve seems low. I have a cinder block on my right foot and manage 14. If you're stock, good chance something's not right.
