2017 Silverado LS DC 2x4 5.3 4.42. 2600 miles. Been averaging 21-23.5 unloaded and 12-13.5 towing my race car (around 5,000 pounds car and trailer). Couldn't be happier

[Listen2hector]

609 miles on odometer (about 200 hwy, 400 city) & DIC shows 16 MPG average (that's with AT tires, level, & front air dam removed)

I get about 18 with 6.5 lift and on 26s

Just got back from a trip from San Antonio, TX to Clearwater, FL and I averaged 20 mpg with an average speed between 70 and 80. 2wd 5.3 with AFE intake, 20" wheels set at 38psi

[Dnt]

6.2 8spd gets consistently over 20 MPG for around 17,000 miles

 

A lot of remote starts and probably 50% city driving, plus a LEAD FOOTED driver LOL. Could probably get over 30 MPG if I was a hypermilling type of guy......... Here is a video of my standard takeoff!

In the past 785 miles I've gotten 22.0. 5.3 DC 3.42

[gtbigup01]

I drive 55.5 miles daily from my driveway to work, and about 40 of that is interstate cruise control set to 74MPH. DIC readout is a 22.X MPG. Manual calculation at fill up is always 2.X mpg less. Don't get carried away with the DIC readout on any vehicle. The same week I purchased my truck I made a trip to AL from TN, a 4 1/2 hr trip. Got as high as 25.X from DIC readout lol. Looked good, and was close with manual calculations. Mountains in TN kept the numbers going down.

I get 15.5 -16.5 around town without my Range device. Worst with it.

Took a 7 hour trip up to Kansas last week. 20.9 going up without the Range device, 18.6 coming back with the Range device. Wind wasn't a factor.

 

Stock '14 LTZ CC w/5.3L 4X4 and I've removed the rear spacer blocks. No toneau.

Over 70k miles. Solid average is 13.5

Has a lift but stock sized tires currently. Have 11k on stock sized tires and I get about 13.5 -14mpg

I just hit the 20k mile mark and owned the truck for 3 years tomorrow. My lifetime (hand calculated) mpg is 19.2. Last 2 years the air dam has been off but everything else stock. It appears the air dam cost me about 0.2mpg but I don't do a lot of interstate driving so my results may be different than somebody else who does.

90000 miles on the truck. I bought it at 42k and this shows how many miles I have put on the truck since I got it. Pretty happy with those numbers, for a full size truck.

I just completed a 400 mile round trip covering I-99/Rt 15 in NY/PA. My truck averaged 23 MPG during the trip. The road is very hilly. My '13 on the same trip would average 20 MPG.
