So... what type of gas mileage do each of the engines get?

[mikemc422]

I tried searching for threads with this info, but couldn't find anything. I'm wondering what each of the engines will get as far as mpg... I'm mainly looking at the Tahoe/Yukon with the 4.8/5.3 and Yukon XL with the 6.0, but drove (and really liked) a Suburban 2500 with the 8.1 today, so I'm considering them as well... I think it'd be helpful to other prospective buyers to have all the engines and their gas mileages/power outputs all in one place as well (if possible)...

I've been driving my 2003 tahoe z71 with the 5.3 for two days now and have been getting 18 mpg based on 100 miles driven so far. 70 percent freeway. I know that is not enough track record but I had the same truck years ago and was consistent getting around 17 with mostly freeway and 15 city.

Of course weather makes a difference. In snow and using 4x4 you will get less.

But for everyday driving I'd say between 15 and 17

Seams a little low for an 07. Aren't those suppose to get better with the active fuel management. I figured the 07 and up would get like 18-20

I drove a 2015 model Tahoe that I rented from Michigan to Chicago. About a 400 mile trip. I averaged 19.7 mpg. Mostly freeway though

My mom has a 2016 LTZ it's amazing how much technology advanced in 9 years 60mph on flat roads high 20s in that but mine could just be becuase the engines old or the first model year the technology wasn't 100% there or maybe driving habits

My 2005 LTZ with the 5.3 gets almost 15 in town, 16-17 freeway, depending on speed.

My 01 Tahoe gets around 14-15 in town. My first big trip with her will be this weekend, heading to Jacksonville for the Raiders game

That's the first place I looked lol, they only have the smaller engines though (4.8 and 5.3). I haven't been able to find EPA estimates or much on what you can actually expect with the larger engines.

Probably driving habits lol, my aunts 07 Escalade got 18-19 around town and 22+ on the highway (depending on speed) when she was good but it got down to 8-10 mpg when she wanted to have some fun
