Curious about what everyone is getting for combined fuel mileage-
Post up your motor/trans combination and any mods you have along with mileage.
I’ve got the 5.3 10speed/ 1.5 level and 295/70/18. Pulsar LT with AFM disabled I’m currently getting 17.9 mpg combined.
 
5.3 with the 10 speed also, factory tires and lift.
Pulsar LT with DFM off, 17.8 mpg.

I will say that I am 90% highway driving though, would be much worse if all city miles.
 
2021 5.3 10 speed. No DFM, no Auto Stop. GU5 3.23 gears. Best 23.7, Avg. 17. Stock lift, 295 70 18 Falken Wildpeak AT3's.

I have the same setup with a lift and 35" tires and I get 22.3 on highway and 13 depending on off road dares. Not much city driving. Never bought it for gas mileage though.
 
5.3 10spd. I avg 18mpg with 2in level and 295/70-18s.
 
5.3 LT Trail boss - 6 inch BDS lift- 35x12.5x18R wheels, pulsar, SBS CAI.. 13.2 MPG

I have the 2.7 ho engine and average 16.7 but I pull a trailer with it every week so that throws it. When I’m not pulling it averages 18-19mpgs and can get crazy good mileage if I’m careful and lay off the gas pedal.
 
3.0 duramax 22' LT TB, stock. 1,000 miles so far. Best 50 mile average: 29.8. In town/daily average around 23.

I’m getting 22 combined if I keep my foot out of it. If I drive with my foot in it I’m getting about 13. 5.3. 10 speed
