Combined fuel mileage

[TonyBoss]

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.

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 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.
