Considering 2012-2015 Suburban, have a few questions

[gmcman]

I was after the 8.1 but have moved more to the newer-ish models. This will be more of a family hauler with fewer towing jobs than planned.

I know these aren't meant for stellar MPG's, but the high teens, low 20's is also welcome.

One question is for the owners of the 6.0 2500 burb, what is your highway MPG without a trailer?

The 1500 5.3 is likely where I will be but the tow rating is dismal. Also worried about the AFM which is why I'm looking at the 2015 model.

Just trying to gather my thoughts and seek opinions. The 6.0 seems to be the better drivetrain at a cost of MPG's.

What are you looking to tow? How many people are in your family?

The 2008-2013/14 2500 Suburban/Yukon XL with the 6.0/3.73 with the 6 speed might get you 17mpg not towing on the highway. My Express with the 3.42 would get 18mpg all day long on the highway and over 20mpg at 60 mph.

I budget for 20mpg with the Suburban in my signature for highway driving. At 60mph I will easily get mid 20’s with our truck.

If you are looking at the 1500, I would highly recommend getting a 2015 or newer. My 2017 Suburban with the 3.08 tows as good or better than my 2012 Yukon XL with the 3.42. The bump in HP and Torque between 2014 and 2015 makes a difference. My 2012 also was not as consistent with fuel mileage and I would say it averaged 17mpg at best on the highway.

Anything over that, you're dreaming and less than 15mpg is where it will be for combined, city/highway.

That I believe, but also considering the 1500/5.3/3.42

I guess it depends on how you drive it. When I say 20 MPG, I'm talking filling up and jumping on the highway,prob cruise 65 ish.

Really the only reason I threw that in there was we rented a 2015 to go to the beach and it would get 20 on the highway all day long.

I just don't know how the pre 2015s were with AFM. I'm fine with mid teens for the 6.0 2500.

2002 Tahoe 5.3, about 14-15 mpg strictly highway, 13-14mpg combined.
2016 Silverado CC 4wd 5.3 (basically a 1/2 ton burb with a bed) 16-17 highway bobtail, if I drove slow, 70mph or so.

There isn't a suburban out there that gets 20mpg unless it's downhill!

11 or 12 mpg in town 14 to 15 hwy. 6.0 loves gas

Yes, meant to include this will be a used vehicle search.
