Depends who is driving.
Me town/highway 15/19
Wife. Summer 12/18. Winter 4/7

So ill vote down the middle since her mpg offsets mine

Just did a round trip from Peoria il to Chicago and on the way idk what my tail wind was but got 21mpg at 85mpg going up but 12.5 was the best i could manage at 65 on the way back with the head wind lol.

I am in the middle group on the MPG poll.
13-15 city/17-19 highway

I just got my 2004 5.3L Tahoe Z71 less than two months ago.
I am really pleased the Tahoe does noticeably better than the 4.0L 05 Jeep TJ Rubicon with 33x12.5 tires I used to have.

Granted, the Tahoe now only has 245/75 R16 pizza cutter tires on...

I swapped (they were free/even Steven exchange) over to some stock Silverado 16 inch alloy rims, so I could have more choices at cheaper prices than 20 inch rims that it came with from the PO.
I am fine with the tiny, skinny 245's for this season. The fat tires I had on the Jeep were not fun in winter driving or hitting deep puddles on the highway; and the mileage was about 12.5 on a good day with a tail wind.

My MPG might drop a little, when I switch over to 265/75 R16 in the spring. But, I don't thing the mileage will suffer too much with that upgrade.
For the size, weight and power of the Tahoe... I am impressed it does as well as it does on a tank of gas. VERY happy coming from the Jeep to Tahoe world!

Bone Stock 2003 245k on the clock. 14-15 city and 19-21 on the highway depending on wind direction and which highway/interstate (speed limits vary). I 99% of the time run 87 octane.

I know it is not a Tahoe, but it has the same drivetrain from the trans back as my Tahoe (L33 instead of L59) but the Silverado has 17.1 total lifetime mpg average. Father in law never reset mileage in 400k lol. Ok hijack over.
