You have a K2 and get 12 MPG around town? Is that like New York City city driving or like Los Angeles or Fort Lauderdale city driving? What's your average speed on a tank of gas that delivers 12 mpg?

I have K1500 and it’s like New York City driving and average speed will be around 30-40 mph I believe

What year? Are you asking for specific PPV vehicles?

I have 2016 4x4 PPV and I think 12 mpg City is a bit too much? Should be around 15mpg?

It's supposed to get 16 MPG CITY and 18 Combined. Failing cats will usually first manifest themselves through reduced gas mileage before throwing codes. Start with the simple and less expensive checks and maintenance first though.

There is a guy on here who drives in downtown Miami traffic @Jorge1313 and his MPGs are often in the single digits. Gary @Miami-Dade drives in Miami and NYC with his Tahoe.

I bought it just a month ago and it’s my first Tahoe,
Went to dealer and did some maintenance.
I’m thinking to clean cat using lacquer thinner.
People say this method worked well for them

checked some websites where people report their real MPG's and average was between 15-16, just a few reports with 12-13 MPG's.
Ordered OBD scan tool with live data that able to monitor O2 sensors how they perform... will see

I get around 11 mpg in the city and about 16 mpg on the highway. I do, however, have a heavy foot and a Black Bear performance tune.

If my wife is in the truck with me on longer trips, I can top out at 18 mpg on the highway.

 

[George Owens]

Im averaging about 11.5 mpg, mostly city driving

 

[RST Dana]

Usually 16 city 22 or more highway if I am less than 70. 70 and above I get 19 on cruise. I’m happy. @BlackBearPerf tuned it for 89 while on the highway.

I don't have y'alls model, but those are nice numbers. My 08 6.2 Denali got 20 mpg highway at sustained 85 mph on a cross country trip. She does NOT get your 16mpg city.

The new models are impressive city for sure.

I know I don't belong here but I thought I would chime in...

6, yes that's 6 MPG lol. It did go down from 8-9 (93 oct) when I switched to E85. That's all city with a heavy foot. Highway I used to get 14-15 cruising on 93. E85 took a 20-25% MPG hit but it costs me 30-40% less than premium. It also makes about 10% more power at the wheels. Honestly, who cares...

Not too many 950hp cars or 6k LB trucks that can get over 6-8mpg on E85 that I know of. It’s pretty damn healthy if you ask me, ran a 11.77 qtr mile on really heavy 22” snow tires last month. I’m sure I’d pick up 1-2mpg just by lightening up my tire/wheel combo.

*When I’m not driving it like I stole it, I can get 15-16mpg Highway on premium which is better than it does from the factory. MPG is just a number, you may go through more fuel on E85 but it’s cheaper fuel so it’s cheaper per mile. It’s the per Mile cost that matters and I really don’t care anyways or I’d buy a Prius or Tesla and not build a 1k HP race truck

I get about the same on the highway in mine. City 14mpg.

I have a 2012 Yukon Denali with factory tires and about 55K mileage. It has a 1.9L Magnuson supercharger with a 10psi pully, BlackBear tune, headers with cats and a Borla sport exhaust. I drive pretty sporty and average between 13-14 in the city. That being said, I live in a rural area and rarely get stuck in stop and go traffic. From a weight perspective, I keep the rear seats out most of the time.

Some update

got recently check engine code P0420, so I decided to use lacquer thinner. On a half tank, I put a gallon of thinner and drove 150 miles on the highway.
Code has gone and MPG went from 11 to 16, so far happy with results...Still have emission check issue with "EVAP system not ready" will dig that problem...
